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.

Prestressed box girder bridge
Štíchová, Kateřina ; Štefan, Petr (referee) ; Koláček, Jan (advisor)
The subject of this diploma thesis is the design of a load–bearing structure, whitch is situated in the extravillain between the town of Chomutov and the village Křimov. Main purpose of this structure is to pass a roadway I/7 across the valley. There are three options of design and one of them – the prestressed box girder bridge with slanted walls is chosen for more detailed elaboration. The major load–bearing structure is five–span with lenghts 46.50 + 58.00 + 58.00 + 58.00 + 46.50 m, made of post–tensioned nad cast–in–place concrete. The total lenght of load–bearing structure is 269.00 m and the width of load–bearing structure is 13.50 m, the bridge is straight in plan. The structure is analyzed by several computational models, which are designed in Scia Engineer 20.0 software. The structure is analysed in longitudinal and cross directions. The assessments of load state limit and usability limit state are made according to valid standards. This thesis also included time dependent analysis (TDA), that takes construction stage analysis into account.

Slab bridge across the local creek
Štíchová, Kateřina ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The subject of this bachelor thesis is the design of a load–bearing structure in the village Velké Karlovice, which passes a roadway II/481 across the watercourse. There are three options of design and one of them – the variant of prestressed slab structure is chosen for more detailed elaboration. The span between bridge supports is 19.50 m and total width of the slab structure is 12.00 m. The slab structure is solved in two ways– – by the manual calculation (for check) and also by creation of the calculation slab model in the program. The manual calculation is based on element of 1.00 m widht and 19.5 m length, which is taken out of the slab. The statical model of this element is a sample beam. The internal forces are obtained from the manual calculation and they are compared with the forces of the slab model. The assessments are solved on the slab model according to valid standards.
