The subject of diploma thesis is designing multi-span highway bridge over Řepovský potok valley, dirt roads and biocorridor. Three variants of bridge were designed and one of them – box girder 10 span bridge, has been chosen. Bridge deck is made from cast in place post tension prestressed beam. Load-bearing structure is concreting step by step on fixed and moving support. Total length of bridge is 560 m. The analysis of structure was projected on several computational models. They have been made in software Midas Civil and SCIA Engineer 18.1. The assessments of ultimate limit state and serviceability limit state were made in all steps of building in longitudinal and cross direction. In the analysis in longitudinal direction is included the time dependent analysis. Structural design was made in software MS Excel according to valid standards. Finally, drawing documentation and visualization were made.

The diploma thesis is focused on design of a monolithic reinforced concrete structure of an apartment building situated in a gap site. The foundation is designed on a foundation slab supported by piles, which together with the walls in the basement are made as a waterproofness concrete structure. It is a two-way wall construction system, made in a combination of masonry and reinforced concrete. The structure was assessed for the ultimate limit state and the serviceability limit state. Due to the requirement for waterproofness, the reinforcement was designed for non-force effects at an early stage. The work includes drawings of shapes and reinforcement.

The aim of final thesis is design and assessment of footbridge over highway D1 in Bohumín. The design is processed in two options. From these two options there is cable-stayed construction solved in greater detail. Because counstruction is in circular arch with small radius, it is necessary to contain real geometry to computational model. Model is created by beams and construction stages are included too. The construction is assessed for the ultimate and serviceability limit state according to valid standards. In the thesis is performed eigenvalue analysis and harmonic response of the construction. Detailed drawings are included too.

Diploma thesis deals with design and assessment of a ceiling of a library in Ostrava. The solved beamed ceiling is above the third floor. Static analysis of the structure was calculated by Scia Engineer 20 software. Two variants of ceiling was calculated. Thesis then focuses on prestressed ceiling.

The subject of this diploma thesis is structural design of a car showroom building in Olomouc. The layout dimensions are 16 x 37 m, the roof is designed as a 5° slope half span roof with cantilever hanging of 6 m. Roof layout dimensions are therefore 22 x 37 m. The object is designed as a two – storey building with two levels of second floor. Maximum height of the structure is about 9,0 m. The design is based on a study of two materiál variants – timber and steel structure. More suitable variant was chosen and following drawings, structural design report and technical report were processed. Main structural system is designed as a one rigid corner column – girder connection, 6 m axis dimensions. Main structural material is a glued laminated timber, completed with coniferous timber and steel elements. The roofing is supported by rafters which are connected to the main roof truss. Bearing element of floors is a Novatop Element structural systém. The spatial rigidity of structure is ensured by steel stiffeners. Structural analysis was carried out by finite element method in software Scia Engineer 21, where the design of the basic elements for ultimate limit state and serviceability limit state was made. Connection design was processed manuály and with software Idea Statica and Hilti Engineering Suite.

The aim of the Master´s thesis is to design the prestressed floor construction of the shopping centre. The construction is supported by the columns with the maximal span dimensions 16,0*16,6 m. The design is made according to the VSL (VSL International Ltd.)slab system - post-tensioned slab prestressed by the unbonded system of 4 monostrand units. In the thesis there is also made a simplified design of the reinforced concrete floor construction supported with the bigger amount of the columns. It is made a comparison of the both types of the floor slabs and the evaluation of their advantages and disadvantages. The statical analysis and the calculation of the internal forces is assessed by the program Nexis 3.60.15 32.

The topic of this thesis is design and evaluation of the bridge structure. Three variants of bridging were created, among which the variant with prestressed girder deck and seven spans was chosen to detail processing. The bridge construction is built on sliding steel girder in several stages. Construction is evaluated considering the ultimate serviceability state and ultimate limit state. Emphasis is also on evaluation of construction stages. The calculation of load effects and analysis of building in stages was done in Scia Engineer 19.1 software. Design and evaluation were done according to currently valid European standards.

The purpose of the work is to study the effect of fiber on the physical and mechanical characteristics of concrete and to develop recommendations for the production of dispersed reinforced structures. As a result of the research work, the principles of optimizing the structure of fiber concrete due to the influence of fiber length on the mechanical strength properties are proposed. Using graphical methods derived statistical dependence of the qualitative characteristics (prism strength, modulus of elasticity, Poisson's ratio) of fiber-reinforced concrete from prescription-technological parameters of the dispersed reinforcement, which improves the bearing capacity of concrete structures or to reduce the amount of steel reinforcement. / Цель работы - изучение влияния фибры на физико-механические характеристики бетона и разработка рекомендаций по изготовлению дисперсно-армированных конструкций. В результате проведенной исследовательской работы предложены принципы оптимизации структуры фибробетона за счет влияния длины волокон на механико-прочностные свойства. С помощью графических методов выведены статистические зависимости качественных характеристик (призменная прочность, модуль упругости, коэффициент Пуассона) фибробетонов от рецептурно-технологических параметров дисперсного армирования, что позволяет повышать несущую способность бетонных конструкций или уменьшать расход стальной арматуры.

Byggbranschens utsläpp av växthusgaser utgör en stor andel av Sveriges totala utsläpp. För att minska de byggrelaterade utsläppen är det på många fronter som byggbranschen behöver förändras och effektiviseras. De senaste åren har en succesiv ökning av byggandet i trä skett vilket är gynnsamt då trä alternativet är mer klimatvänligt än stål och betong. De tuffa klimatmålen vi nu står framför innebär dock att mer behöver göras än att endast öka andelen träbyggnader. Pappersmassaindustrin är lätt att bortse ifrån, då den hittills inte varit relevant för byggbranschen och för att återanvändning är relativt framträdande inom den branschen. Ifrån sågverken som sönderdelar trästockar till virke fraktas flis som blir över till pappersbruk. Av flisen görs sedan bland annat diverse pappförpackningar som går att återvinna. Problemet är att dessa förpackningar endast går att återvinna ett visst antal gånger innan fibrerna blir obrukbara och istället används som biobränsle. Om byggmaterial skulle gå att producera baserat på dessa fibrer, skulle detta innebära en mer långlivad användning av dem. Ett byggmaterial som uppfunnits, gjort på fibrer från pappersmassabruk är core-materialet ”Greenwood”. Eftersom materialet är nytt och egenskaperna till stor del är okända krävs det att diverse studier görs som undersöker materialets olika egenskaper som är relevanta för en eventuell tillämpning inom byggbranschen. Denna studie avser att undersöka skjuvstyvhet, böjstyvhet och bärförmåga hos sandwichelement uppbyggda av core-materialet Greenwood och ytskikt av papp. Detta genom att först  dynamiskt och statiskt testa de ingående materialens egenskaper, följt av böjprovning av nio sandwichbalkar med varierande tjocklek på ytskikten. Samtliga balkar testades även dynamiskt. Core-materialet Greenwood som ingick i sandwichelementen var endast den begränsande faktorn en gång av tio böjprov. När core-materialets skjuvstyvhet togs fram både dynamiskt och statiskt och när den omvandlades till en skjuvmodul visade det sig att Greenwood har en mer än dubbelt så stor styvhet som EPS-cellplast vid liknande densitet. Detta är intressant då denna cellplast ofta agerar som ett core-material i sandwichelement ute i byggbranschen. Testerna visar även på att balkarna har en relativt liten spridning vilket innebär att resultaten har god tillförlitlighet. Slutligen, kan det konstateras att dessa sandwichelement uppvisar sega egenskaper med en viss kvarvarande lastkapacitet även efter brott. Samtliga nämnda egenskaper ovan talar för en viss potential för tillämpning av dessa sandwichelement inom byggbranschen. Fortsatta studier av fukt- och krypegenskaper vid långtidsbelastning rekommenderas, vilket är viktigt för användning inom byggandet. De omfattande resultaten från föreliggande studie utgör dock ett bra underlag för fortsatta undersökningar och värdering av möjliga tillämpningar. / The construction industry`s greenhouse emissions, makes up for a large portion of Sweden’s total emissions. In order to reduce construction related emissions, a fair amount of fronts within the construction industry needs to be changed and streamlined. In the last couple of years, there has been a successive increase in the number of structures that are built from wood amongst other things, which is beneficial because the wood alternative is more climate friendly than steel and concrete. The current tough climate goals entails that more has to be done than just increasing the amount of wood constructions. The pulp industry is easy to write off because so far, it has not been relevant to the construction industry and because recycling is relatively prominent within that industry. From the sawmills that dismember wooden logs to lumber, leftover wood chips are transported to paper mills. Among other things, different cardboard packages that can be recycled are then made from those wood chips. The problem with these packages is that they can only be recycled a certain number of times before the fibers become unusable and instead, are used as biofuel. If building materials were to be able to be produced with these fibers, that would be a more long-lived use of them. A building material, recently invented, made of fiber from paper mills is the core-material “Greenwood”. Because the material is new and its properties for the most part are unknown, this requires that various studies are conducted that examines the different properties the material possesses that are relevant for a contingent enforcement within the construction industry. This study intends to examine the shear rigidity, flexural rigidity and maximum capacity for sandwich panels made from the core-material Greenwood and faces of paperboard. This was achieved by first dynamically and statically test the properties of the two different materials, followed by flexure testing nine sandwich beams with varying face thicknesses. Every beam was also tested dynamically. The core-material Greenwood which was a part of the sandwich panels, was only the limiting factor 1 time out of 10 flexure tests. When the shear rigidity of the core-material was calculated both statically and dynamically and when it was converted to a shear modulus it was shown that Greenwood has a rigidity of more than double that of EPS cellular plastic at similar density. This is interesting because this type of cellular plastic often acts as a core-material in sandwich structures found in the construction industry. The tests also show that the beams have a relatively small spread which means that the results have good reliability. Finally, it can be concluded that these  sandwich panels exhibit ductile properties with a certain lasting load capacity even after ultimate load has been reached. Every property mentioned above indicates that there is a certain potential for applicability of these sandwich panels within the construction industry. Continued studies of moisture properties and creep properties during long-term loading is recommended, which is important for a possible use within construction. The extensive results from this study constitutes a good basis for continued research and assessment of possible applications.

Byggbranschen bidrar till stora utsläpp av växthusgaser, och det är därför viktigt att utforska hållbara material för att minska påverkan. Studien fokuserar på grundfundament för mindre trähus i Sverige, där betong i platta på mark ersätts med korslimmat trä (KLT) för att reducera klimatpåverkan. Eftersom betong har hög tryckhållfasthet gjordes analys av kantbalkens kapacitet. Fyra alternativ på kantbalkar undersöks: KLT/EPS400, KLT/Foamglas, KLT/EPS s100 och EPS400. Studien bedömer även den nuvarande dimensioneringen i hållfasthetsberäkningarna. Testdata för tryckhållfasthet används för att jämföra med förväntade resultat och avgöra om beräkningsmodellen ”2:1 metoden” är tillräcklig.Syftet är att bedöma möjligheterna för användning i två hustyper hos en ledande hustillverkare i Sverige. Miljöpåverkan av alternativen beräknas med IVL Svenska Miljöinstitutets verktyg, BM, där även en betonggrund jämförs. Det utförs även en enklare insikt i skillnader av produktion mellan en klassisk betonggrund och Klaragrunden. Studien visade att 1-plansvillan Lycke kan utföras med KLT och EPS s100, och att 1,5-plansvillan Tyresund kan se möjligheter med KLT och FoamglasT4+. Studien visade också att den bästa genomsnittliga grunden är KLT och EPS s400. Genom att byta ut betongen i en platta på mark med KLT, gör det möjligt att sänka grundens CO2 utsläpp med 65-68%. / The construction industry contributes significantly to greenhouse gas emissions, making it crucial to explore sustainable materials to reduce its impact. This study focuses on foundation systems for small wooden houses in Sweden, where concrete slabs are replaced with cross-laminated timber (CLT) to decrease climate impact. Due to concrete's high compressive strength, an analysis of the edge beam's capacity was done. Four edge beam alternatives are examined: CLT/EPS400, CLT/Foamglas, CLT/EPS s100, and EPS400. The study also evaluates the current dimensioning in strength calculations. Compression strength test data is used to compare with expected results and determine if the calculation model "2:1 method" is sufficient. The aim is to assess the possibilities for use in two house types from a leading house manufacturer in Sweden. The environmental impact of the alternatives is calculated using IVL Swedish Environmental Institute's tool, BM, where a concrete foundation is also compared. There is also a brief insight into the differences in production between a traditional concrete foundation and Klaragrunden. The findings indicated that the single-story villa Lycke can be constructed using CLT and EPS s100, while the 1.5-story villa Tyresund can explore possibilities with CLT and Foamglas T4+. Moreover, the study revealed that the CLT and EPS s400 combination yielded the best average foundation. By replacing the concrete in a ground slab with CLT, it is possible to reduce the CO2 emissions from the foundation by 65-68%.
