Bridge over a local road
Kováč, Daniel ; Mojzík, Petr (referee) ; Nečas, Radim (advisor)
This master thesis is focused for design, respectively for creating counterproposal of existing structure of Motorway Bridge located at D1 motorway between Jánovce and Jablonov in district Levoča in Slovakia. This bridge is over a local road. The main aim of this thesis is design, analysis and assessment of bearing elements of bridge deck. For purposes of this thesis was created three variants of bridge deck. Detailed analysis was performed on bearing construction from post-tensioned precast beam with monolithing concrete slab. Two mathematic models were used for analysis of chosen variant. First model was spatial 3D shell construction. The purpose of this model was determinate cross spreading line of other constant load and live load. Second, flat 2D model, was for determination creep and shrinkage appeared from long-term load. These effects were observed in at advanced defined time nodes. Outcomes from upper mentioned model were used from design and assessment of bearing elements of bridge deck, design prestressed reinforcement cables and concrete reinforcement rods.

Design of a prestressed concrete bridge on the road I/38
Valent, Matej ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The diploma thesis deals with the design of an additionally prestressed and horizontally curved bridge structure on the 1st class road. The bridge is located on the newly emerging southeast bypass near the Czech town of Havlíčkův Brod. Three variants of the main supporting structure were proposed, with the choice being a chambered cross-section with inclined side walls. The total span of the bridge, with a length of 273,0m, was divided into 7 spans. The thesis also includes the design of the construction sequence. An assessment of the ultimate limit state and serviceability was carried out. Visualization and drawing documentation have been prepared for the thesis.

Design of prefabricated concrete hall
Cibičková, Viktória ; Chalivopulos, Paris (referee) ; Zich, Miloš (advisor)
The diploma thesis is focused on the design and assessment of a precast concrete hall. The first part of the work deals with the selection of a suitable layout solution from several proposed variants and a description of the technical solution of the object. After the load calculation, which corresponds to the nature of the building's use and climatic conditions, is followed by an assessment of selected elements of the structure, such as a typical purlin, girder, columns and foundation structures. The static assessment was determined through computational models and was accompanied by a manual simplified calculation check. The next part is devoted to creating a study of the structure's behavior. In the study, the design of several versions of the steel bracing system of the object was evaluated. The task was to choose the most suitable variant. Another goal of the study was the evaluation of the results of the global model from the nonlinear assessment through the software, as well as the evaluation of the results of the deformation caused by entering flexible supports into the computer software. In the last part, the proposed structure is demonstrated through assembly drawings, drawings of the shape and reinforcement of selected elements, drawings of assembly details, bearings and forgings. Visualizations of the object are part of the drawing documentation.
