Michel, Kenan 06 October 2020 (has links)
Das seitliche Kraftwiderstandssystem, in diesem Fall Stahlbetonkernwände eines 10-stöckigen Gebäudes, das aus Schwerkraftstützen und Scherwänden besteht, wurde linear (unter der Annahme eines linearen elastischen Materialverhaltens von Beton) und nichtlinear gerissen (unter Berücksichtigung des Materialverhaltens von Beton) unter seismische Belastung analysiert. Erst wurde die grundlegenden Methode der äquivalenten Seitenkraft zur Schätzung der seismischen Belastungen benutzt, später wurde die aktuelle Methode The Performance Based Seismic Design verwendet, bei der reale seismische Aufzeichnungen verwendet werden und die Beschleunigungen mithilfe der Software ETABS auf das Gebäude angewendet werden. Nach dem Anwenden der Beschleunigungen wurden die maximal resultierenden Kräfte und Verformungen bewertet. Das Gebäude wurde dann für die maximal resultierenden Kräfte ausgelegt.Der Inhalt des Hauptberichts ist: - Allgemeine Beschreibung des Gebäudes, seismische Standortinformationen, Standortantwortspektren, Belastung und seismische Kräfte einschließlich Analyse des modalen Antwortspektrums. - Lineares Design des Modells für Schwerkraft und seismische Belastungen, P-M-Wechselwirkungsdiagramme für den U-Querschnitt aus Stahlbeton, Entwurf einer Längs- und Schubbewehrung der Scherwände und des Koppelbalkens. - Zwei Varianten des nichtlinearen Modells, bei denen die Kernwand (Scherwände) gemäß jeder Variante entworfen wird, wobei der Einfluss des Dämpfungsmodells auf das nichtlineare dynamische Verhalten sowie der Einfluss des Kopplungsstrahlmodells auf das nichtlineare dynamische Verhalten untersucht werden. - Entwurfsüberprüfung, erst mit der Definition der Leistungsobjekte und Modell für die Zeitverlaufsanalyse.

Klinga, Niloofar, Selvad, Tomas January 2015 (has links)
Examensarbetet kom som en förfrågan från företaget Northpower stålhallar AB som var i behov av en beräkningsmall för vind- och snölast. Beräkningsmallen utformas i Microsoft Excel och den ska möta de önskemål och krav som tillkommer vid projektering av en hallbyggnad. Beräkningsmallen grundas på en litteraturstudie av vind- och snölast kapitlen i Eurokoderna som inleder den teoretiska delen av rapporten. För att se skillnader mellan stomstabiliseringssystem som vanligen används i hallbyggnader, utfördes en litteraturstudie på vanligt förekommande systemen. En kraftanalys vid olika placeringar av företagets nuvarande stomstabiliseringssystem gjordes med hjälp av den tillverkade beräkningsmallen. Litteraturstudien och analysen sammanställdes till jämförelse av de olika stomstabiliseringssystemen. / The subject of this bachelor thesis was a query from Northpower stålhallar AB that was in need of a calculation model for wind- and snow loads. The Calculation model was created in Microsoft Excel and shall satisfy the requirements for the design of an industrial building. The calculation model is founded on a literature study of Eurocodes wind- and snow load chapters, which initializes the theoretical part of the report. To gain a better understanding of the differences between the different types of bracing systems that is normally used in industrial buildings, we performed a literature study on a selection of the usual systems.  Using the calculation model, a force analysis on different placing’s of the current lateral stability system the company use was carried out. The thesis ends with a comparison of the study and analysis of the different lateral stability systems that’s been studied.

An Investigation of External Support Choices and Behaviours During One-Handed Exertions with Constrained Reaches

Liebregts, Julian H. January 2014 (has links)
Introduction: External support behaviours, which include leaning (supporting with the non-task hand) or bracing (supporting with the body), are frequently employed by workers in manufacturing settings. However, current ergonomic assessment tools are limited by our limited understanding of these behaviours. Recent studies have investigated these behaviours, however, the designs of these studies are limited in their applicability to real-world scenarios. The purpose of this study was to assess how different task parameters affect the prediction of external support behaviours, as well as the effect of support on task hand, and body, kinematics and kinetics, in a minimally constrained experimental design. Methods: Female participants (n = 18) performed a series of one-handed maximal exertions (in the six orthogonal directions), and one precision task, in four hand Locations. Trials either featured support (as chosen by the participant), or no support. Results & Discussion: Three logistic regression models were developed, with inputs from individual and task characteristics, and they correctly predicted the occurrence of leaning, bracing, or simultaneous leaning and bracing, 74-86% of the time. Leaning and/or bracing were found to provide: 1) oppositional forces to increase task hand force generation, 2) balance, by countering destabilizing moments about the feet, and 3) a reduction in moment arm of the task hand force, with respect to the upper body joints, by bringing the shoulder closer to the task hand. Participants were able to exert 64.8% more force at the task hand as a result of support. Leaning hand placement depended on the task force direction and location. However, the positioning of the leaning hand varied very little. Finally, the precision condition showed that fine motor demands may also affect external support choice. / Thesis / Master of Science in Kinesiology

Evaluation of Non-invasive Treatment Options for Children and Adolescents with Pectus Carinatum : An Evaluation of Patient Satisfaction, Adherence and an Exploration of the Social and Psychological Impact of Non-invasive Treatment Options - A Systematic Review / Evaluation of Non-invasive Treatment Options for Children and Adolescents with Pectus Carinatum : An Evaluation of Patient Satisfaction, Adherence and an Exploration of the Social and Psychological Impact of Non-invasive Treatment Options - A Systematic Review

Pettersson, Karin January 2023 (has links)
This review aimed to evaluate orthotic treatments for children and adolescents with pectus carinatum, primarily focusing on patient satisfaction with the treatment. Secondary outcomes of interest were adherence and psychological and social factors following the treatment period. A literature search was performed in the databases CINHAL, Medline, Web of Science and Scopus. Following predetermined eligibility criteria, articles were included and excluded. Next, criticala ppraisal was performed for the included articles. Following this, relevant data were extracted, analysed, and presented to aid in answering the research questions. Six articles with 402 patients were included in the final review. Patient satisfaction was good or improved following the treatment period, and the combined non-adherence rate for the included orthosis was 37.7 %. Patients adhering to the treatment protocol showed increased self-esteem and decreased interference with social activity following orthotic correction. Moreover, they displayed significantly higher patient satisfaction than patient's non-adherent to the treatment protocol. The findings were displayed and discussed in the Bio-Psycho-Social model. Due to their connection, patient satisfaction and adherence were placed together in the middle and surrounded bypsychological and social factors. The model displayed that a combination of many aspects determines patient satisfaction and adherence, demonstrating that treatment is complex and challenging. In conclusion, adherence was deemed one of the most important aspects to achieve high patient satisfaction. Moreover, due to psychological and social factors, a patient-centred approach with professional collaboration is necessary to achieve successful outcomes. To make reliable conclusions, research of higher quality with long follow-up periods including standardised patient satisfaction and adherence measures is needed.

Seismic analysis and retrofitting of an existing multi-storey building in Stockholm

Muca, Matilda, Haikal, Celine January 2018 (has links)
Throughout the years earthquakes are a huge concern for structures; causing losses of peoples’ lives, damages and collapse of homes. Usually, most of the buildings that collapse or have serious damages are mostly old buildings that do not fulfil any longer the updated regulations and building codes concerning seismic design. The purpose of this Master’s thesis is to analyse and strengthen an existing building given by the company Sweco, by using proper and innovative retrofitting techniques; considering Eurocode 8 and collected data from previous studies. The selected building is a seven-storey structure in Stockholm; consists of prefabricated concrete and steel elements and is tested under seismic loading to investigate the global behaviour of the structure using the software MIDAS GEN. Two analyses are performed; assessment analysis which includes modelling of the given structure where the structural capacities are studied. The second analysis is the seismic analysis which includes two secondary analyses; before seismic retrofitting and after seismic retrofitting respectively. In the seismic analysis before the seismic retrofitting is applied, the main scope is to identify the most critical positions of the building where it behaves abnormally and the displacements are high enough in order to modify the structure to decrease displacements. Moreover, the frequencies were obtained and examined. The second seismic analysis includes the modified structure; where it was tested with different alternative methods of seismic retrofitting in order to identify which technique is the most proper one to optimise the strength and the structural performance of the given building. Finally, it appeared that a combination of seismic retrofitting methodologies was the most suitable selection. The selected combination consists of steel bracings and prefabricated reinforced concrete walls (shear walls). After performing the seismic retrofitting analysis, results of the frequencies and displacements of the structure were acquired and compared with the un-retrofitted analysis. The obtained results displayed that using this structural modification improved by increasing the frequency in the transverse direction (y) by 57.2%, in the longitudinal direction (x) by 27.6% and rotational along the z-axis by 12.9%; lastly, by decreasing the displacements in the x- and y-direction remarkably. Consequently, a combination of innovative seismic retrofitting methods appeared to be more effective, achieving a more resistant building under seismic hazards, by improving the stability and ductility of the structure. This gives rise to further researches and investigations for future solutions regarding seismic retrofitting applications and methodologies. / Jordbävningar är skakningar i marken som orsakar förluster av människors liv och leder till skador och kollaps av byggnader. Vanligtvis är de flesta byggnader som har allvarligt skadats eller kollapsat, äldre byggnader som inte längre uppfyller de uppdaterade byggreglerna för seismisk design. Syftet med detta examensarbete är att analysera och stärka en befintlig byggnad som har distribuerats av konsult företaget Sweco; lämpliga och innovativa seismisk eftermonteringsmetoder har använts för att förbättra byggnadens tillstånd med hjälp av insamlat vetenskapliga artiklar, tidskrifter och tidigare examensarbete samt svensk standard (Eurokod 8 - för dimensionering av bärverk med avseende på jordbävning). Den utdelade byggnaden är sju våningar hög och ligger i Stockholm. Den består av prefabricerade betong- och stålelement. Byggnaden kommer att testas under seismisk belastning med hjälp av programvaran MIDAS GEN, för att sedan examinera byggnadens globala beteende. Två analyser har utförts; en bedömningsanalys som innefattar granskning av den givna byggnadens kapacitet. Den andra analysen är den seismiska analysen som omfattar två sekundära analyser; en ’före applikation av seismisk eftermonteringsmetod’ och en ’efter applikation av seismisk eftermonteringsmetod’. I den första seismiska analysen, identifieras de mest kritiska positionerna där byggnadens beteende är avvikande med höga förskjutningar och låga frekvenser; således, är behovet av att modifiera och förbättra byggnadens prestanda betydande. Den andra seismiska analysen innefattar den modifierade byggnaden, som har testats med olika alternativa seismiska eftermonteringsmetoder för att identifiera vilken teknik som är mest passande för att optimera byggnadens hållfasthet, elasticitet och prestanda. Efter många experimentella försök, framgick det att en kombination av varierande seismiska eftermonteringsmetoder var det mest lämpliga urvalet. Den valda kombinationen består av stålfackverk och skjuvväggar. Efter genomförandet av den seismiska eftermonteringsanalysen erhölls resultat av frekvensen och förskjutningarna av byggnaden som sedan jämfördes med den första seismiska analysen, innan en eftermonteringsmetod var tillämpad. De erhållna resultaten visade att valet av denna modifikation har förbättrat byggnadens prestanda genom att öka frekvensen i tvärriktningen (y) med 57,2%, i längdriktningen (x) med 27.6% och rotationsfrekvensen längs z-axeln med 12.9%; slutligen, genom att minska förskjutningarna i x- och y-riktningen anmärkningsvärt. Följaktligen, verkade en kombination av varierande seismiska eftermonteringsmetoder vara effektiv, vilket resulterade i en seismisk resistent byggnad med avsevärt god hållfasthet, elasticitet och stabilitet. Denna forskning ger upphov till ytterligare efterforskningar och undersökningar för framtida lösningar avseende seismiska eftermonteringsapplikationer och metoder.

Seismic Retrofit of Reinforced Concrete Frame Buildings with Tension Only Braces

Khosravi, Sadegh 13 October 2021 (has links)
Reinforced concrete buildings built prior to the enactment of modern seismic codes are often seismically deficient. These buildings may have inadequate strength and ductility to withstand strong earthquakes. Conventional retrofit techniques for such frame buildings involve adding reinforced concrete shear walls or structural bracing systems to the existing bays. These techniques can be intrusive and result in lengthy down times and expensive structural interventions. An alternative to conventional techniques is the use of high-strength prestressing strands or cables, diagonally placed as tension elements. This technique was researched and used in a limited manner after the 1985 Mexico City Earthquake. It has since been further investigated at the University of Ottawa through experimental and analytical research (Shalouf and Saatcioglu (2006), Carrière (2008), Molaei (2014)). While the use of steel strands as tension bracing elements proves to be an effective technique, the resulting stiffening effects on the frames lead to increased seismic force demands and higher based shear, as well as increased axial forces on the attached columns, potentially generating net tension, foundation uplift and excessive compression. Relatively low elongation characteristics of high-strength cables and slack caused by yielding strands and associated pinching of hysteresis curves reduce potential energy dissipation capacity. The current research aims to improve the previously observed deficiencies of the system. One of the improvements involve the use of shape memory alloys (SMA) in the middle of the cables, which reduce/eliminate residual deformations upon yielding and associated pinching of the hysteresis curves. SMA allows energy dissipation in the system while forcing the structure to recover from its inelastic deformations because of the flag-shape hysteretic characteristics of the material. The feasibility of the cable-SMA assembly as tension brace elements is illustrated through dynamic analyses of selected prototype buildings. The other improvement is the development of progressively engaging, initially loose multiple strands as tension cables. These cables are placed loosely to engage in seismic resistance at pre-determined drift levels, thereby eliminating premature increase in seismic force demands until their participation is required as the frame capacity is reached. Tests of a large-scale reinforced concrete frame, designed following the requirements of the 1965 National Building Code of Canada NRC (1965) as representative of existing older frame buildings in Canada, are conducted under simulated seismic loading to assess the effectiveness of the proposed system. The verification of the concept is extended analytically to prototype buildings and the effectiveness of the system is demonstrated for mid-rise and low-rise frame buildings.
