Lávka přes Labe / Footbridge across the Labe

Krč, Rostislav January 2017 (has links)
The thesis focuses on design of prestressed concrete footbridge which passes pedestrian and bicycle path over the Elbe river near city of Celakovice in the Czech Republic. Three different bridge options were analyzed and for further development a cable-stayed footbridge was chosen. Its bridge deck is formed of a box girder supported by cables in its vertical axis and all cable stays are anchored into two concrete A-shaped pylons. This structure was analyzed in SCIA Engineer and assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Both the global structural behavior and the local structural integrity of box cross-section were assessed as well as construction stages and cross-sections of pylons and cable stays. Assessments were performed in IDEA StatiCa combined with hand calculations. Eventually a dynamic response of structure was analyzed. Natural modes and frequencies were found and forced oscillation response was evaluated. The thesis includes technical drawings, construction process and visualization.

Nosná konstrukce horského hotelu / Load-bearing structure of mountain hotel

Kudličková, Jitka January 2017 (has links)
Master’s thesis is based on analysis and design of a load bearing structure of an mountains hotel. Mountain hotel schould be realized in the village Vernirovice in Šumperk district. The proposed structure is formed 4th floors. In 1.NP is a restaurant, a sports and wellness center. In 2.NP in the right side is situated the swimming pool. In 2 to 4 floor are located rooms. This structure is supported with a strip footing made of reinforced concrete. The main load-bearing elements in the vertical direction are in 1.NP reinforced concrete walls and columns, the upper floors bearing masonry walls of ceramic blocks THERM. The inner support walls are 300 mm thick, outside support walls are 400 mm thick. Floors are constructed of carrying plates with girders above the larger openings. These plates and girders are made of reinforced concrete. In the 2 floor are beams with the span of 8,8 m. These girders are designed of prestressed concrete cause the large loads. Individual levels are connected with monolithic concrete staircases. Around the middle of the building is a monolithic reinforced concrete elevator shaft. The highest elevation above grade level is 16 m. The thesis also deals with relevant drawing documentations for chosen parts of construction.The building is located in the ski area VI and IV wind areas.

Evaluation and Structural Behavior of Deteriorated Precast, Prestressed Concrete Box Beams

Ryan T Whelchel (7874897) 22 November 2019 (has links)
Adjacent precast, prestressed box beam bridges have a history of poor performance and have been observed to exhibit common types of deterioration including longitudinal cracking, concrete spalling, and deterioration of the concrete top flange. The nature of these types of deterioration leads to uncertainty of the extent and effect of deterioration on structural behavior. Due to limitations in previous research and understanding of the strength of deteriorated box beam bridges, conservative assumptions are being made for the assessment and load rating of these bridges. Furthermore, the design of new box beam bridges, which can offer an efficient and economical solution, is often discouraged due to poor past performance. Therefore, the objective of this research is to develop improved recommendations for the inspection, load rating, and design of adjacent box beam bridges. Through a series of bridge inspections, deteriorated box beams were identified and acquired for experimental testing. The extent of corrosion was determined through visual inspection, non-destructive evaluation, and destructive evaluation. Non-destructive tests (NDT) included the use of connectionless electrical pulse response analysis (CEPRA), ground penetrating radar (GPR), and half-cell potentials. The deteriorated capacity was determined through structural testing, and an analysis procedure was developed to estimate deteriorated behavior. A rehabilitation procedure was also developed to restore load transfer of adjacent beams in cases where shear key failures are suspected. Based on the understanding of deterioration developed through study of deteriorated adjacent box beam bridges, improved inspection and load rating procedure are provided along with design recommendations for the next generation of box beam bridges.

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.

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.

Polyfunkční dům / Multifunctional building

Mikudík, Patrik January 2022 (has links)
The subject of the diploma thesis is to elaborate the project documentation of a newbuilt multifunctional building in Považská Bystrica. The multifunkcional building is designed as a three-storey without basemen. In the first ground floor there are dental and gynecological surgeries with facilites, a cafe and director's office. In the second there are office spaces with facilities for rent. On the level of the third floor there are two-rooms flats and one four-room flat, while there are also storage spaces for each of the flats. The building of the multifunctional house is based on reinforced concrete foundations. The vertical construction system consist of reinforced concrete perimeter walls and perimeter reinforced concrete columns in combination with an internal load-bearing walls of the reinforcing core of the building. The partition walls are designed as a plasterboard walls. The horizontal load-bearing structures are made of reinforced concrete prestressed panels. The roofing of the building is designed as a flat one-layer roof. The roof of the terrace consist of an extensive vegetation flat one-layer roof. The roofing of the awning at the main entrance to the building is design as a reinforced concrete monolithic console with one-layer flat roof a skylight. The building is insulated with the external thermal insulation composite system (ETICS). The façade of the communication core of the building is made of brick cladding. The rest of the façade is made of a thin layer white plaster.

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.
