One span frame bridge
Buk, Petr ; Zich, Miloš (referee) ; Nečas, Radim (advisor)
The subject of this bachelor thesis is design of road bridge across the river. From the developed variants, one was selected. Selected variant deals with one span frame bridge. Construction is made of panel with run-ups from prestressed reinforced concrete. Bridge is designed perpendicular, with span range of 25,0 m. For the calculation of internal forces two computing models (rod and panel model) were made in SCIA Engineer 2018 program. Thesis deals with comparisons of internal forces in rod and panel model and comparison of short-term losses with SCIA Engineer 2018 program. Design and assesment of ultimate limit state and ultimate serviceability state was conducted in accordance with applicable standarts and regulations.

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.

Prestressed bridge slab
Stoklasová, Andrea ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The aim of the thesis is to design the one pole slab bridge. As a material of the supporting structure has been chosen prestressed concrete. Three preliminary studies have been designed, one of them is selected as the most appropriate solution, and then further elaborated. The span of the bridge is 20 meters. The load effects is calculated using Scia Engineer 17.1 and then compared by manual calculation. An assessment has been made of the ultimate and the serviceability limit state.

Bridge across the river Svitava
Mičánek, Ondřej ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The subject of this bachelor thesis is the design of superstructure of footbridge over the Svitava river. The design is processed by three options. The chosen option is designed as an arch bridge with a lower prestressed bridge deck, suspended on a steel arch. Bridge is designed as perpendicular, simply placed on the outer supports. The lenght of of the superstructure is 46,8 m. and the lenght of the bridging is 44 m. The steel arch is designed as a second stage parabola with a 6 m stiffness. The calculation of load effects was done by SCIA Engineer 2017 software. Design and structural assessment reports are designed according to the valid standards and regulations.

Design of the bridge in the industry area
Lipus, Rostislav ; Svoboda, Adam (referee) ; Klusáček, Ladislav (advisor)
The aim of this bachelor‘s thesis is the design and analysis of the concrete bridge in industrial area across river Balinka. Thesis contains static analysis of single span bridge which was chosen from three variants. Final variant is sloping prestressed concrete deck supported by two supports. Calculations were made by Scia Engineering software and compared with manual calculation. The supporting structure is assessed for the ultimate limit state and serviceability limit state The design is created in accordance with ČSN EN 1992-2. This thesis does not contain the time dependent analysis.

Design of a railway frame bridge
Findura, David ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
This thesis deals with a design of a two-track railway frame bridge over a valley. Out of three proposed variants was chosen the variant number 1 - prestressed frame construction with variable beam section. According to actual EN standards the construction was designed and assessed to the serviceability limit state and the ultimate limit state.

Slab bridge
Barák, Radek ; Koláček, Jan (referee) ; Panáček, Josef (advisor)
The subject of this bachelor thesis is the design of a load-bearing structure of a perpendicular bridge over the Krupa River behind the town of Hanušovice. The bridge turns the II. class road 446, which is a category of S 7,5. For the design, studies of three variants of one-span bridge are processed. The selected variant is solved by means of an additional prestressed plate of rectangular cross-section of height of 900 mm and length of 21,765 m. It is statically designed as the support storage bridge with length of 19,670 m. The design was done according to ČSN EN 1992 - 2. The calculations of the load effects were performed by SCIA ENGINEER 2015 software. The design and assessmetns are solved according to valid standards and regulations.
