KL-träbjälklag i kombination med stålstommar : Teknisk utvärdering och utveckling av lösningar för förband och längre spännvidderSidén, Marja January 2017 (has links)
En i dagsläget vanlig byggteknik i Sverige är användandet av en stålstomme i kombination medprefabricerade betonghåldäck. Detta arbete grundar sig på frågeställningen om KL-träbjälklag skullekunna vara ett reellt alternativ till betongbjälklag i en sådan konstruktion, i kombination medhattbalkar. Som ett första steg skisserades en typkonstruktion för att ha en väl definierad utgångspunkt för enanalys. Utgångspunkten för denna typkonstruktion var främst en studie av två tidigare konstruktioner,konstruerade med stålstomme med hattbalkar och håldäcksbjälklag. Litteraturstudien fokuserade påbakomliggande teorier i relation till bjälklagets funktion i konstruktionen. Ett antal områdendefinierades som utgångspunkt för en teknisk utvärdering. Dessa områden var spännvidder,dimensionering i brottgränstillståndet, dimensionering i bruksgränstillståndet, knutpunkter,dimensionering för olyckslaster, akustik och byggbarhet. Utgående från ovanstående områdenutvärderades så tekniska förutsättningar för användandet av KL-träbjälklag i den aktuellakonstruktionstypen. Det konstaterades att det på många områden finns väl fungerande lösningar ochatt det finns många positiva aspekter med ett lätt och lättmonterat KL-träbjälklag. De problemområdensom hittats kan sammanfattas som: 1. Begränsad spännvidd 2. Ökade horisontella deformationer i bjälklaget 3. Beräkning av svängningar med hänsyn till upplag på stålbalkar 4. Förband mellan bjälklag och hattbalkar 5. Akustisk dimensionering Två av dessa områden valdes för vidare analys; förband mellan bjälklag och hattbalkar samt denbegränsade spännvidden. För förbandet utvecklades en lösning med en klack på hattbalkens fläns ikombination med en slits i KL-träskivan som enkelt ska kunna hakas på vid montage. För att ta krafterlängs balkens längd måste dock lösningen sedan kompletteras med ett skruvförband genombalkflänsen. Förhoppningen är att en enklare lösning för att ta dessa förhållandevis små krafter skakunna utvecklas som komplement till det primära förbandet med klack och slits. Handberäkningarutfördes för det utvecklade förbandet och det konstaterades att det är möjligt att utforma ett sådantförband, med rimliga dimensioner, för alla verkande laster. Som den sista delen av arbetet studerades lösningar för att kunna uppnå längre spännvidder, för ettplattbjälklag är spännvidden begränsad till något mindre än 7,7m. Olika typer av samverkansbjälklagstuderades och det konstaterades att samverkan med ett prefabricerat betongbjälklag med en limmadförbindelse skulle kunna vara en lämplig lösning. Limmade förbindelser studerades så mer ingåendeoch det konstaterades att en limmad förbindelse mellan trä och prefabricerad betong medför storstyrka och styvhet. Upp mot 100% samverkan har observerats för samverkansbjälklag med denna typav förbindelse. En osäkerhetsfaktor är dock långtidseffekter, där fler studier behöver hittas ellerutföras för att få en större kunskap på området. Handberäkningar utfördes enligt teorin i SS-EN 1995-1-1 på två typer av samverkansbjälklag med ett antal olika dimensioner. I beräkningarna medräknades100% samverkansgrad. Det konstaterades att 9m spännvidd skulle kunna uppnås med en kombinationav KL-trä och betong, medan 12m spännvidd kan uppnås med hjälp av mellanliggande träreglar. Andraberäkningsmodeller för svängningar där egenfrekvensen inte är den begränsande faktorn skulle kunna leda till bättre resultat för denna typ av samverkansbjälklag. / A currently common building technology in Sweden is the use of a steel structure in combination withprefabricated HD/F concrete slabs. This work is based on the issue of whether CLT slabs could be asuitable alternative to concrete slabs in such a structure, in combination with the type of weldedplated beams that are often called hat beams. As a first step a type-structure was sketched to have a well-defined starting point for an analyze. Thebasis for this structure was mainly a study of two designs constructed with steel structures composedof hat beams and HD/F slabs. The literature study was focused on underlying theories in relation to theslabs function in the structure. A number of areas were defined as a basis for an evaluation of thebuilding type. These areas where spans, design in the ultimate limit state, design in the serviceabilitylimit state, joints, design for accidental actions, acoustics and constructability. Based on the above,technical conditions for the use of CLT slabs in the building type in question were evaluated. It wasfound that in many areas there were working solutions, and that there are many positive aspectsrelated to the use of a light and easily mounted CLT slab. The issues that were found can be concluded as: 1. Limited span lengths 2. An increase of horizontal deformations in the slab 3. Calculations of vibrations with respect to the flexible support 4. Joints between slabs and hat beams 5. Acoustic design Two of these issues were chosen for further analysis: joints between slabs and beams and the limitedspan length. A solution was developed for the joint, composed of a heel on the flange of the steelbeam in combination with a slit in the CLT slab. The joint is supposedly easy to mount during assembly.To be able to handle the forces along the length of the beam the solution must however becomplemented with a secondary screw joint through the flange of the beam. The hope is that a simplersolution to handle these relatively small forces can be developed, as complement to the primary jointmade up of the heel and slit. Calculations were performed by hand for the developed joint and it wasfound that it is possible to design such a joint, with reasonable dimensions, for all the acting loads. As the last part solutions to achieve longer spans were studied, for a flat CLT slab the span length islimited to somewhat less than 7,7m. Different types of composite slabs were studied and it was notedthat a composite with a prefabricated concrete slab and a glued connection could be a suitablesolution. Glued connections were then studied more closely, and I was found that a glued connectionbetween wood and prefabricated concrete entails great strength and rigidity. About 100% unitedaction has been observed for this type of connection. An uncertain factor is however long-term effectswhere further studies need to be found or performed to achieve more knowledge. Hand calculationswere performed using the theory in SS-EN 1995-1-1 on two types of composite slabs for a couple ofdifferent dimensions. In the calculations 100% united action was used. It was found that 9m span couldbe achieved with the combined action of CLT and concrete, while 12m could be achieved using woodenstuds for spacing. Other theories for the calculations where the natural frequency isn’t the limiting factor could lead to better results for this kind of composite slabs.

Byggbara höga modulhus : Dynamisk analys av punkthus med trästomme / Buildable high-rise modular housing : Dynamic analysis of timber buildingsHäggström, Rickard, Olsson, Pär January 2019 (has links)
I denna studie studerades det hur ett 14 våningar högt bostadshus med en kärna av korslaminerat trä (KL-trä) och färdiga lägenhetsmoduler med regelstomme kan byggas på ett industrialiserat och enkelt sätt. Våningsantalet och produktionstypen fastslogs tidigt, i samråd med RISE, för att effektivt kunna granska ett sannolikt sätt att bygga hus i en nära framtid. Dynamiska modalanalyser utfördes för byggnadens olika modeller i FEM-programmet Robot Structural Analysis (kommer fortsättningsvis även beskrivas som Robot) för att ta fram egenfrekvenser. Sedan följdes en beräkningsgång från Eurokod och EKS för att ta fram den toppacceleration som vind orsakar på byggnadens högsta plan. Detta värde jämfördes sedan med det rekommenderade komfortkravet från ISO 10137. Byggnaden som studerades är ett punkthus med en central kärna och 14 moduler, av storlek 4 x 8 meter, per våning. Dessa placeras runt den 8 x 8 meter stora kärnan, vilket gav ett totalt fotavtryck på 24 x 24 meter. Över 20 olika datormodeller studerades där bland annat variationer av placering och mängd av KL-trä i fasad, placering och andel betong i huset och påverkan från gipsskivor i inner- och ytterväggar. Även infästning mellan moduler tillhör några av de ändringar som studerades. Resultatet visar att det är möjligt att bygga den modell som benämns 1400KL i vindlastzon 24 och terrängtyp tre, förutsatt att den mekaniska dämpningen är satt till 2 procent. Det framgår även att modulernas egna lägenhetsavskiljande väggar har signifikant betydelse för stommens totala stabilitet och att en ökning av styvheten i dessa är ett effektivt sätt att förbättra de dynamiska egenskaperna. Betydelsen av mycket massa högt upp i byggnaden är också tydlig utifrån detta arbete. Det framkommer även att stabila betongvåningar nederst i stommen bidrar mycket till att förhindra att översta våningen i huset rör sig obehagligt mycket vid stor vindbelastning på byggnaden. Detta är en beprövad teknik i basen av flertalet hus som byggs idag. Rotation har visat sig vilja förekomma i de tidigare modeller som använts i denna rapport. Detta är något som måste testas specifikt för alla varianter av basmodellen då rotation är ofördelaktigt ur dynamisk aspekt, då det saknas beräkningssätt för dynamiskrotation i teorin från Eurokod. Generellt kan tillägas att ett 14 våningar högt trähus i vindlastzon 26 och terrängtyp 0 har väldigt svårt att klara av de dynamiska förutsättningar som krävs utan att husets stabiliserande element till största del består av betong. Däremot finns flera trä-modeller i denna rapport som klarar vindlastzon 25 och terrängtyp tre, en mycket mer vanlig situation. Enklare statisk analys antyder att limträpelares dimensioner möjliggör montage mellan moduler utan större produktionsanpassning. Även korslaminerat trä inkluderas fördelaktigt i kärna och fasad, innanför och utanför modulerna, utan att det påverkar de traditionella konstruktionsmetoderna för vare sig moduler eller KL-stomme väsentligt. / In this study, it was examined how a 14-story tall residential building with a core of cross laminated timber (CLT) and prefabricated apartment modules can be built in an industrialized manner. The number of floors and production type were determined early, in consultation with RISE, in order to effectively examine a likely way of building houses in the near future. Dynamic modal analyses were performed for the building's various models in the FEM program Robot Structural Analysis to generate eigen frequencies. Then the method provided in Eurocode and EKS were followed to calculate the top acceleration that the wind causes at the buildings highest floor. This value was then compared with the recommended comfort requirement from ISO 10137. The studied building is a high-rise tower block house with a central core and 14 modules of size 4 x 8 meters per floor. These were placed around the 8 x 8-meter-wide core, giving a total footprint of 24 x 24 meters. Over 20 different computer models were studied with variations in placement and amount of CLT in facade, placement and number of concrete floors and walls. The impact of gypsum inner and outer walls is also being tested. Connections between modules also belongs to some of the changes that were being made between models. The result shows that it is possible to build the model named 1400KL in wind zone 24 and terrain type III, with the mechanical dampening set at two percent. It is also apparent that the walls of modules separating apartments have considerable significance for the overall stability of the frame and that increasing their stiffness is an effective way of improving dynamic properties. It can be concluded from this study that placing a substantial mass at the top of the building is of high importance. It also appears that rigid concrete stories at the bottom of the core contribute greatly to prevent the top floor of the house from exceeding the comfort criteria under high wind loads. This is a widely used technique in the base of houses being built today. Rotation has been shown to appear in the models used in this work. This is something that must be tested specifically for all variants of the base model since rotation is disadvantageous from a dynamic aspect. This is due to the fact that the codes do not consider dynamic rotation. In general, a 14-storey high-rise wooden house in wind zone 26 and terrain type 0 does not fulfil the comfort requirements without most of the stabilizing elements of the house being concrete. On the other hand, there were several wooden models in this study that can endure wind zone 25 and terrain type III, a much more common situation. A simplified static analysis suggests that glulam columns can have dimensions that allow them be placed between modules without major adaptation in production. Also, cross-laminated timber is advantageously included in the core and facade, inside and outside the modules, without significantly affecting the traditional design methods for modules or the cross-laminated frame.

Balkonger i trähus : Systematisering av konstruktionsarbeteErsson, Tina January 2019 (has links)
House construction today is largely project-based, where the buildings are tailored tounique conditions and locations that are rarely the same as another build on anotherbuilding site. In addition to the building itself and the building site, involved actorsusually also change from project to project. As a result of today's project-basedconstruction, there is a lack of a standardized and systematic work process forconstruction work. A systematic work process could contribute to all the players' pursuitof profit. To explore the possibilities of creating an improved work process, this study focusedon balconies of wooden houses. The purpose and objectives of the work were therefore designed to evaluate today'sconstruction work for the design of balconies in wooden houses, where possible areasof improvement were evaluated to create a systematic work process for constructorsin designing and dimensioning balconies in wooden houses.In order to achieve the purpose and objectives of the work, four questions have beendeveloped that focus on the production of systematic work processes, the current workprocess of the construction work, design methods and balconies in wooden houses.Existing research and published material were found through a literature and contextstudy to further develop the study’s work. Theory regarding systematisation and process development, balconies,dimensioning of supporting structures, etc. was the basis for how the work would becarried out. The systematized work process for balcony design was, however, createdusing information from the qualitative interview study with a total of eight (8)respondents in different roles I house building. The work process was then partiallytested in a quantitative verification. The work resulted in a systematic work process in the form of a checklist that includesgeneral tips as well as a chronological workflow that describes how, when, with whomand what should and can be done at the balcony design to get the best possible results.A description of the existing balcony types has also been developed to simplify workand to clarify important points and tasks in the design of a particular type of balcony. The workflow is divided into the activities of the design and dimensioning, such asstart-up, design and dimensioning of the balcony's main components, detail designand dimensioning of fastening components, drawing up drawings and assemblydescriptions, and follow-up and development of the work process. Based on the results of the study, the questions were answered with a description ofthe four (4) types of balcony, which were based on theory and were strengthened bymeans of empirical data from the respondents. Two (2) of the balcony types are viiiconsidered more common, balconies with pillars to land and rods above the balconyplate, where the latter is considered the most common in wooden houses at present.Today's construction work for designing and dimensioning balconies in woodenhouses is similar in large part, but due to the use of prefabrication and standardizationdegree the work differs from each other. The verification of a part of the work process resulted in a balcony solution with crosslaminated timber as a balcony slab and in a comparison between results from aproposed software and hand calculations. The comparison showed that the softwarecan be used for dimensioning balconies with cross laminated timber, with the exceptionthat the dimensioning for fire must be done by hand because of deficiencies in thesoftware's settings. The study has shown that systematisation is often based on LEAN Production, whichwas created by the Japanese automotive industry, which focuses on creating efficientwork processes by circularly examining, testing, evaluating and developing workprocesses. The conclusion of the work is that it is possible to systematise construction work, butunlike the manufacturing industry, the work process must have adjustment possibilitiesduring the work to meet the commonly occurring changes in house construction.However, in order for the systematisation work to be carried out, increasedunderstanding and involvement from and by other actors than constructors arerequired. A systematic work process together with type solutions and standardized calculationmethods can shorten the design time, improve and secure the solutions, and allowmore time for creative thinking to further improve the balcony solutions and the workprocess.

KL-träbyggnad utan heltäckande väderskydd - Ett mer fuktsäkert förfarande / CLT-building without comprehensive weather protection - A more moisture proof procedureAhlberg, Oskar, Hultgren, Patrik January 2019 (has links)
Syfte: Syftet med denna studie var att framställa en mall för hur man projekterar KL-träbyggnader fuktsäkrare samt ta fram rekommendationer för ett mer fuktsäkert arbetssätt. KL-trä är ett nytt byggnadsmaterial där behov av standardisering finns för att uppfylla de krav och rekommendationer som finns. Större hänsyn behöver tas till fukt då människors hygien och hälsa ej skall påverkas. Metod: Genom insamling av data med hjälp av fallstudie av ett flerbostadshus i KL-trä framgår såväl materialhantering som utformning av stomme och väderskydd. Utformning av stomme framgår fortsatt genom dokumentanalys av konstruktionshandlingar för tre KL-trähusprojekt. Vidare framgår branschens förhållningssätt och erfarenheter genom intervjuer av personer med olika ämnesrelevanta kunskaper. Resultat: Genom att i tidigt projekteringsskede prioritera fuktsäkerhet för såväl uppförande- som bruksskede reduceras risken för fuktrelaterade problem. Vidare bör det kontinuerligt arbetas med fuktsäkerhet gemensamt, mellan discipliner i projektet. Byggnadsdelar att ta särskild hänsyn till samt åtgärder för att utföra detta presenteras såväl som rekommendationer för ett mer fuktsäkert arbetssätt. Konsekvenser: Studiens resultat skall verka som ett komplement till ByggaF, detta då resultatet behandlar KL-trä specifikt. Genom implementering är förhoppningen att resultatet skall reducera risken för fuktrelaterade problem i KL-träbyggnader. Vidare bör högre krav ställas på fuktsäkerhet vid KL-träbyggnationer, detta då resultatet av dagens arbetssätt är okänt och försiktighetsprincipen bör tillämpas. Begränsningar: Studiens resultat, i form av den projekteringsmall som genererats, är i huvudsak tillämpbar för arkitekter och konstruktörer då endast stommen utreds. Resultatet är generellt tillämpbart för nybyggnation av flerbostadshus i KL-trä som uppförs i Sverige. Vidare utreds åtgärder för att reducera risken för fuktrelaterade problem och avser ej människors påverkan av mikrobiell påväxt. / Purpose: The purpose of this study was to produce a template for how to design CLT buildings moisture-safer and to make recommendations for a moisture-safe working method. CLT is a new building material where there is a need for standardization to meet the requirements and recommendations that exist. Greater consideration needs to be given to moisture in order for people's hygiene and health not to be affected. Method: By collecting data using a case study of a multi-story house in CLT, material handling as well as design of framework and weather protection are shown. Design of framework appears through document analysis of design documents for three CLT house projects. Furthermore, the industry's approach and experience are disclosed through interviews of people with different subject-relevant knowledge. Findings: By, in the early design stage, prioritizing moisture safety for both construction- and use stages the risk of moisture-related problems is reduced. Furthermore, it should be continuously and jointly worked with moisture safety between disciplines in the project. Building components to take special account of and measures to do this are presented as well as recommendations for a more moisture-proof working method. Implications: The results of the study should be a complement to ByggaF, this is because the result specifically addresses CLT. Through implementation, the hope is that the result will reduce the risk of moisture-related problems in CLT buildings. Furthermore, higher requirements should be set on moisture safety in CLT construction, as the result of the current working method is unknown and the precautionary principle should be applied. Limitations: The study's result, in form of the design template that is generated, are mainly applicable to architects and designers as only the framework is investigated. The result is generally applicable for new-construction of multi-story buildings in CLT which are constructed in Sweden. Furthermore, measures to reduce the risk of moisture-related problems are being investigated and does not refer to people's influence by microbial growth.

Foreign Language Learning in Santo Domingo: Qualitative Case Studies in Two Private SchoolsNoble, Priscilla Garrido 03 July 2007 (has links)
Improving the teaching of English as a foreign language in public schools is a high priority for the Dominican administration elected in 2004. Consequently, the government’s plan of action includes a pilot project that integrates language teaching strategies and methods already found in the country’s private, K-12, foreign language programs. The purpose of this naturalistic inquiry was to investigate English teaching through case studies at two private schools in hopes of guiding the country’s educational policy. The schools were selected based on their contrasting methods of foreign language instruction. One school, Imersão, follows a structured immersion program where most academic subjects are taught in English. The second school, Cervantina, teaches all subjects in Spanish, the students’ first language, and provides one hour a day of English instruction. The research process included repeated observations of classroom activities, interviews with administrators, staff and students, and reviewing teachers’ lesson plans and student products in English. The study found that effective English language teaching can be accomplished through varying methods, as elements that promote language learning were seen in each of the schools. The programs were observed to be similar in the importance placed on meeting the academic needs of students with differing abilities, as well as cultural and linguistic backgrounds, by having language classes emphasize the importance of grammar and vocabulary alongside culturally relevant authentic communication opportunities. Even though students at both schools are able to communicate orally and in writing in English, Imersão students appear better equipped to contend with complex academic situations in the second language. However, in order to concentrate almost entirely on the teaching of English, Imersão falls short of the immersion objective of concomitantly developing the primary language at age-appropriate levels. The results also suggest that encouraging students to analyze, deduce, and think in the foreign language while learning subject content in English is advantageous. Future research into this topic should explore where the threshold of optimum exposure to the foreign language inside and outside of the classroom might be in order to achieve language proficiency, therefore allowing the administration to maximize the use of limited education resources.

A case study of Turkish teachers’ perceptions and practices regarding Communicative Language Teaching in EnglishBrodin, Martina January 2014 (has links)
The aim of this study was to gain an insight into how teachers work practically with the Communicative Oriented Curriculum in English and what factors that could influence the teachers’ methodology. The investigation partially replicated a study by Kırkgöz (2008). The study was conducted at three state elementary schools in Turkey by using multidimensional qualitative research procedures, including classroom observations and interviews. Results demonstrated that all participants showed attributes identified to an Eclectic-Oriented teaching approach placing them in the middle of a continuum from Transmission to Interpretation-Oriented teachers. The results were later compared with the original study displaying both a satisfying and unsatisfying outcome depending on a qualitative or quantitative comparison. Findings also indicated that a holistic perspective must be considered in order to interpret and understand the results.

Felsvarsanalys vid bedömning av flerspråkiga barns ordförråd : En kvantitativ och kvalitativ studie kring ordförrådsutvecklingen hos svensk-turkiska 4- och 7-åringar via ordförrådstestet Cross-linguistic Lexical Task (CLT)Sender, Camilla, Svensson, Malin January 2018 (has links)
The knowledge about typical vocabulary development in bilingual children is limited, which is why bilingual children incorrectly might be diagnosed with language impairment. The aim of this study is to investigate the Swedish vocabulary of 4- and 7-year-old bilingual Swedish-Turkish children via the vocabulary test Cross-linguistic Lexical Task (CLT). The assessment has been carried out earlier within the project BiLI-TAS and included 52 children, equally distributed over the two age groups, who both understood and spoke Swedish and Turkish. The test included both production and comprehension of nouns and verbs. The authors of this thesis have analysed the incorrect answers given by the children in the production part of the vocabulary test. The responses were categorised through an elaborated category system to map out the word knowledge of the children in detail. The emphasis of the study was on the qualitative analysis, although a quantitative analysis was also made of all parts of the test. The results of the quantitative analyses showed that the 7-year-old children had a higher result (96,6 points) than the 4-year-old children (67,5 points) on all parts of the test (120 points in total). The difference between the age groups was significant. Both age groups achieved higher results when nouns were tested than when verbs were. This difference was small but significant. One third of the participants got equal or higher results in the verb part than in the noun part of the test. The results of the qualitative analysis showed that the younger children more often than the older children used alternative ways to express themselves than through the Swedish language (they used Turkish or gestures). The older children more often chose to not give any response or to make a circumlocution or invent a new word. Both age groups made more taxonomic errors (e.g. bird instead of the target word owl) than thematic associations (e.g. paint instead of the target word paintbrush), which suggests that the syntagmatic-paradigmatic shift begins earlier than other studies have shown (Holmström, Salameh, Nettelbladt, & Dahlgren Sandberg, 2016; Namei, 2004). However, the 7-year-old children made more taxonomic errors than the 4-year-old children. The conclusion of this study was that a qualitative analysis of the incorrect answers in a vocabulary test may complement a quantitative analysis by giving information about the children’s word knowledge. This may hopefully give important clues when diagnosing language impairment in the future. Kunskapen kring flerspråkiga barns typiska ordförrådsutveckling är begränsad. Detta gör att flerspråkiga barn riskerar att felaktigt diagnosticeras med språkstörning. Syftet med denna studie är att via ordförrådstestet Cross-linguistic Lexical Task (CLT) undersöka det svenska ordförrådet hos flerspråkiga svensk-turkiska 4- och 7-åringar. Testningen har genomförts tidigare inom projektet BiLI-TAS och omfattade 52 barn, jämnt fördelade över de två åldersgrupperna, som både talade och förstod svenska och turkiska. Testet omfattade såväl förståelse som produktion av både substantiv och verb. Författarna till denna uppsats har analyserat de inkorrekta svar som barnen gett i produktionsdelen av ordförrådstestet genom att kategorisera dessa efter ett utarbetat kategorisystem för att mer ingående kartlägga barnens ordkunskap. Fokus i studien låg på denna kvalitativa undersökning av barnens felsvar, men även en kvantitativ analys av testets samtliga delar har genomförts. Resultaten av den kvantitativa analysen visade att 7-åringarna fick högre resultat (96,6 poäng) än 4-åringarna (67,5 poäng) på samtliga deltester (totalt 120 poäng). Skillnaden mellan grupperna var signifikant. Båda ålders-grupperna fick också ett litet men signifikant högre resultat på substantivdelarna än på verbdelarna av testet. En tredjedel av alla deltagare fick dock lika höga eller högre resultat på verbdelen av testet. Resultaten av den kvalitativa analysen visade att de yngre barnen oftare än de äldre använde andra sätt att uttrycka sig på än med svenska ord (de använde turkiska eller gester). De äldre barnen valde oftare att inte ge någon respons eller att göra en omskrivning eller nyordbildning. Båda åldersgrupperna gjorde fler taxonomiskt relaterade fel (t.ex. fågel istället för målordet uggla) än tematiska associationer (t.ex. måla istället för målordet pensel), vilket tyder på att det syntagmatisk-paradigmatiska skiftet inleds tidigare än vad andra studier visat (Holmström, Salameh, Nettelbladt, & Dahlgren Sandberg, 2016; Namei, 2004). Det förekom dock fler taxonomiskt relaterade felsvar hos 7-åringarna jämfört med hos 4-åringarna. Slutsatsen i denna studie var att en kvalitativ analys av felsvaren i ett ordförrådstest kan komplettera en kvantitativ analys genom att ge information kring barnens ordkunskap. Detta kan förhoppningsvis ge ledtrådar vid diagnosticering av språkstörning i framtiden.

In what ways does the ELT coursebook ECHO 6 fulfill the communicative aspects of the Swedish curriculum for English 6?Degerman, Ylva, Sävhage, Sara January 2017 (has links)
In this essay, the published ELT coursebook ECHO 6 is critically examined. The focus of the examination is the communicative opportunities within ECHO 6. These opportunities are analyzed and concretized with help from the Swedish Curriculum for English 6. In the results section, the communicative opportunities within five selected chapters are explored in depth. Later, these chapters are discussed and contrasted with relevant literature about English teaching in general as well as communicative language teaching. Our conclusion is that ECHO 6 does provide students with several opportunities to communicate and develop communicative skills in English. However, there are essential parts missing in order for the textbook to be completely communicative. Key words: Language teaching, ECHO 6, communication, communicative language teaching (CLT), students, teacher, language skills and language systems.

Non-uniformly distributed compression perpendicular to the grain in steel-CLT connections : Experimental and Numerical Analysis of bearing capacity and displacement behaviour / Non-uniformly distributed compressive loading perpendicular to the grain in steel-CLT connections : Experimental and Numerical Analysis of bearing capacity and displacement behaviourNcube, Noah, Sabaa, Stephen January 2019 (has links)
Previous studies have mainly focused on the behaviour of timber under uniformly distributed compression perpendicular to the grain (CPG) loads. However, there are many practical applications in which timber is loaded by non-uniformly distributed CPG loads. Different design and test codes like the Eurocode 5 (EC5), DIN 1052:2004, ASTM D143- 94 and EN-408:2010 only account for load configurations where timber is subjected to uniformly distributed loads. For specific uniformly distributed load (UDL) configurations the bearing capacity of timber (solid softwood timber or Glulam) in compression is adapted by using a load configuration factor (kc,90) according to EC5, the European code for design of timber structures. EC5 has no guidelines for cross-laminated timber (CLT) under UDL with the exception of the Austrian National Regulations for EC5. In this work, an experimental and numerical study on the bearing capacity and displacement behaviour of CLT subjected to non-uniformly distributed loading (NuDL) is conducted on eight different load configurations. A steel-CLT connection in which the CLT is partially loaded is used in this study. Finite element modelling, performed using the commercial software Abaqus CAE is used as the numerical simulation of the experimental study and is validated by experimental results. Load configuration factors (kc,90) from experimental results are compared with values from the Swedish CLT handbook (KL-Trähandbok). The outcome of the study shows that load configuration factor for NuDL cases is higher than for UDL cases. Hence, for same load configurations a lower CPG strength is required in NuDL than in UDL. Moreover, numerical results feature overall good congruence with the elastic phase of the experiments and have the potential to augment experiments in further understanding other complex steel-CLT connections
