T-beam road bridge
Lipovský, Václav ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The aim of this bachelor thesis is the design a bridge structure. The bridge will transfer a road of a S7,5 category over local river. Three variants were designed, from which the most suitable one was selected and it was further designed. The selected load-bearing structure is an monolithic post-prestressed single-girder bridge with one span. The span of the structure is 28.0 m. The structure has been detailed processing and assessment of the structure for the ultimate limit state and service limit state. Detailed drawings and visualization followed.

Structural assessment of the existing reinforced-concrete frame structure of the production building
Pražan, Jiří ; Krůpa, Pavel (referee) ; Girgle, František (advisor)
The diploma thesis deals with the structural assessment of the existing reinforced concrete frame structure of the production building. The structure under consideration is carried out as a reinforced concrete monolithic frame structure with a discrepancy of 6,15 x 6,15 m (axis). The object has a rectangular plan of 13 x 9 fields. The total dimension is 56 x 81m and is divided into three dilation units on all floors by two inserted 3,65 m wide fields. The building has three above-ground floors and one underground floor. The construction height of the basement is 3,675 m, above ground level 4,0 m. On the west side of the building (axis A) are three reinforced concrete elevator shafts with a dimension of approximately 4,5 x 3,8 m. The envelope and inner partitions are made of bricks full of burned. The work shall include a static assessment of the status quo, a determination of the load capacity and a proposal for appropriate adjustments to ensure static reliability.

Precast concrete frame building of shopping centre
Břeňová, Marie ; Šimůnek, Petr (referee) ; Laníková, Ivana (advisor)
The diploma thesis is focused on the design and review of selected load-bearing elements of the precast hall. Girder is dimensioned in two variants: reinforced and prestressed concrete. Design and assessment of prestressed girder was carried out using the simplified method and the IDEA statica. Column and footing was also dimensioned. All calculations are done in accordance with Eurocode 2.

Analysis of the existing bridge structure
Dvořáková, Lucie ; Olšák, Martin (referee) ; Svoboda, Adam (advisor)
The bachelor thesis deals with the analysis of the existing bridge structure and the subsequent determination of its load capacity according to the limit states of serviceability and load capacity. The bridge on the H1 circuit over the V1 branch has a main superstructure consisting of IS-73 prestressed beams and was built in 1993. The calculation was grasped in two ways, namely by manual calculation on a single IS-73 beam or by converting it to an orthotropic slab.

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.

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.
