Girder road bridge
Tang, Minh Phú ; Požár, Michal (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor thesis is to design a road bridge with a single span. The bridge carries a road of a class III., category S7,5, over the international roads E442. Three studies have been designed. Study C has been chosen for detailed elaboration. It is a monolithic double-girder post-prestressed construction. The calculation of load effects is performed in Scia Engineer 19.1. Only the effect of vertical load effects was considered, while the horizontal effects of the load were not taken into account.

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.

Bridge over a siding
Slovják, Petr ; Olšák, Martin (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor thesis is to design a road bridge. The bridge, part of road II/353, is crossing over a siding. Designed bridge should replace the current one. Three preliminary studies were developed. The chosen variant is designed as single span double-girder prestressed concrete bridge. The span length of the bridge is 23,0 m and pot bearings are used. The load effects are calculated by Scia Engineer.

Reconstruction of the road bridge near the village Holýšov
Svoboda, Adam ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The thesis deals with design of strengthening of existing bridge structure near the village Holýšov using modern method of additional presstresing. The bridge over the river of Radbuza is h-shaped beam bridge, which was built in 1924. In the present state its load capacity is under the limits for bridges situated on first-class roads. Original documentation of the bridge does not exist, the main source of information about construction details is the diagnostics research. The method of reinforcement by post-tensioning by cables in substituted cable ducts is highly efective in terms of the incerease the load capacity of existing bridge structure. The design of strengthening and the final load capacity was verified by static calculation.

Diagnostic and Reconstruction Design of Brick Building in Medlice
Košárek, Jan ; Cikrle, Petr (referee) ; Kocáb, Dalibor (advisor)
Master’s thesis deals with diagnostics and reconstruction of neo-gothic chapel in Medlice. Summary of appropriate testing methods for this chapel is compiled. Visual examination of whole structure have been performed by diagnostics. Masonry element strength was found out at specimens which had were taken out from structure (drill cores and whole bricks). Masonry elements also was tested by Schmidt hammer LB. Mortar was tested by Kucera’s drill. Masonry strength required for static calculation was computed from achieved values. After examination of all structure defects have been designed reconstruction by post-tensioning.

Prestressed road bridge in Staré Město
Krč, Rostislav ; Trenz, Jan (referee) ; Koláček, Jan (advisor)
The thesis focuses on design of superstructure of concrete bridge, which passes a roadway across the river Krupa in the town of Stare Mesto. It is a simple span structure with length of 19 meters. For further elaboration, post-tensioned concrete slab with trapezoidal-shaped cross section was chosen. Assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Furthermore, a design of post-tension according to former Czech technical standards (CSN) was studied. The thesis includes technical drawings and visualization.
