Design of the road bridge in Brno
Kutálek, Jiří ; Čihák, Petr (referee) ; Klusáček, Ladislav (advisor)
The subject of the diploma thesis is a design of a highway bridge across the Svratka river in Brno. Among three options, the arch bridge with a trapezoidal bridge deck from prestressed concrete was chosen. The load effect is calculated with the assistance of Scia Engineer software. The design and the assessment of the structure are made for the ultimate limit state and serviceability limit state. Static assessment is done by hand calculation according to CSN EN 1992-2. The thesis includes drawings and visualizations of the bridge structure.

Railway arch concrete bridge
Škrabal, Jan ; Zlatuška, Karel (referee) ; Koláček, Jan (advisor)
The subject of this diploma thesis is the structural design of a railway bridge over river Dyje based on materials given by my supervisor. The tied arch bridge with prestressed concrete girder is chosen for the structural check. The structural assesment is focused on prestressed concrete girder and basic calculations are made to check steel arch and hangers as well. Eigenvalue analysis provides dynamic properties of this structure. Appendices contain Structural design report, drawings including Construction stages scheme and visualization. For structural analysis Midas Civil software was used. Other used softwares for visualization, and outputs etc are: Lumion12, IdeaStatica, Microsoft excel and Autocad

Multi-span single T-section girder bridge
Koumar, Jan ; Rušar, Jaromír (referee) ; Koláček, Jan (advisor)
The subject of this master thesis is the design and assessment of the load-bearing structure of a bridge that carries a Class I road. Two design options for the bridge were developed, from which a mutli-span prestressed single T-section girder with five spans was selected for detailed assessment for serviceability limit state and ultimate limit state. The superstructure is built on falsework. Particular emphasis is placed on a phased construction solution. The Midas Civil program is used to calculate the global load effects, where the model of the superstructure is a beam. Local assessments are carried out in SCIA Engineer. The calculation is made according to the valid European standards.

Footbridge across the river Opava
Kolář, David ; Romportl, Tomáš (referee) ; Nečas, Radim (advisor)
The master´s thesis topic is design of a footbridge across Opava river. Out of two different designs, a self – anchored suspension footbridge was chosen and necessary documentations wer produced. The primary focus of the thesis is on static design solution with an output of several drawings. The model created in ANSYS includes different load cases together with construction stages. To support the results, checks and hand calculations via MS Excel were completed, as well as static analysis of transverse behaviour of the deck using SCIA Engineer software. Analysis and calculations are compliant to up-to-date coades and respect the funfamentals of analysis due to limit states.

Design of concrete structure of the Letná hotel in Prague
Koníček, Jakub ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The presented master thesis contains the design of selected elements of the supporting structure of the Letná congress hotel. The thesis deals with the design of a six-storey hotel cantilever over 20 m long, which rises over the entrance portals of the Blanka tunnel complex. Moreover, the specificity of the whole project is the necessity to carry out the entire construction of the mentioned part without touching the ground. The described problem was solved primarily using two double to 3 m high prestressed concrete beams. One pair of beams is designed above the roof plane and the other below the plane of the first floor in the cantilever. The tensile forces induced in the vertical supports are transferred by the prestressed columns and with the help of the walls. Construction without ground contact is carried out using suspension on temporary hangers. In the present thesis work, the main beam of the cantilever H1, D1, reinforced concrete slabs of given levels forming the T-section flange of the main beams, the spread walls, the transverse walls under the transversal frames with the main beams and the respective columns have been designed. SCIA Engeneer 22.0, Idea StatiCa Beam 22.0, Idea StatiCa Detail 22.0, PTC MathCad Prime 8, and MS Office 360 Excel 2022 were used to solve this complex construction stage-dependent problem.

Bridge ower the Opavice river
Tang, Minh Phú ; Russnák, Adam (referee) ; Panáček, Josef (advisor)
The diploma thesis deals with the design of a road bridge on the I/57 expressway over the relocation of the cycle path, the Opavice river and the local road, which involves the relocation of the access to the waterworks. The bridge structure is located in the territory of the town of Krnov. A study of the area's bridges is part of the project and three studies have been prepared. Study A was chosen for detailed processing. It is a continuous box girder bridge with three spans. The superstructure is designed as a monolithic, post-tensioned structure. A sliding girder is being investigated for the structure's construction. Scia Engineer 18.1 is used to do the load effects computation. Only the consequences of vertical load effects have been addressed, with no consideration of horizontal load effects. The structure was evaluated using limit states, taking into account the impact of construction on its design.

Pedestrian bridge across the highway D1 in Bohumín
Muroň, Vlastimil ; Puda, Vladimír (referee) ; Nečas, Radim (advisor)
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.

Construction Stages Analysis of a Membrane Structure with Respect to Wind Load
Zajac, Zbyněk
This paper deals with an analysis of a membrane structure loaded with wind pressure with respect to the construction stages. Modern tools allow analysis of structural response to the prestressing of membrane surfaces in the predefined sequence. So far, analytical models of the membrane structures have been simplified and the sequence of construction has been designed afterwards. This process may lead to the oversized elements, because it is not possible to estimate the structural response to the unexpected load on the structure under construction. Besides, the aim of this paper is to point out the meaning of the construction stages analysis of the membrane structures with respect to the safety on a building site.

Bridge over the Senice river
Urbánek, Filip ; Velešík, Marek (referee) ; Panáček, Josef (advisor)
This bachelor's thesis deals with the design of a road bridge over the Senice river. In the beginning of the thesis there are designed three variations of the bridge. The variation with prestressed prefabricated girders with composite slab is chosen for more detailed assessment. Time-dependent analysis is taken into account in the structural design. Detailed structural design is made and selected parts of the construction are checked for ultimate and serviceability limit state by Eurocode. Detailed drawings and visualization are made as well.
