Dálniční vícepolový most / Multi-span highway bridge

Doležal, Lukáš January 2022 (has links)
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.

Bytový dům v proluce / Apartment building in the gap site

Doupovec, Vojtěch January 2022 (has links)
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.

Lávka přes dálnici D1 v Bohumíně / Pedestrian bridge across the highway D1 in Bohumín

Muroň, Vlastimil January 2022 (has links)
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.

Autosalon v Olomouci / Car show room in Olomouc

Mudrák, Štěpán January 2022 (has links)
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.

Předpjatá stropní konstrukce nákupního centra / The prestressed floor construction of the shopping centre

Miechová, Zuzana January 2012 (has links)
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.

Dálniční most přes Trať SŽDC / Highway bridge across a railway

Mičánek, Ondřej Unknown Date (has links)
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.

Undersökning av grundläggningsmetod, kantbalkar utförda med glas, polystyren och korslimmat-trä.

Eliasson, Daniel, Carlsson, Olle January 2023 (has links)
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%.
