Bridge over a local brook
Růžička, Antonín ; Zdražilová, Magda (referee) ; Panáček, Josef (advisor)
Diploma thesis deals with design pre-stressed road bridge over the local brook and field road. There are designed 3 studies, from which variation trapezial point-supported pre-stressed concrete slabroad bridge with 3 spans is chosen. In the structural analysis of the bridge structure is assessed at the ultimate limit state and serviceability by European standards – Eurocodes. It is developed drawings and visualization of the bridge.

Bridge over the Kyselá voda brook valley
Svoboda, Tomáš ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
The subject of the diploma thesis is the design of the ghrinder bridge over the Kyselá voda brook valley. The main topic is static calculation of supporting construction of six span structure. Two studies were executed and the second option, pre-stressed girder bridge was chosen. The lenght of the spans is 27 + 6 x 35 + 27 m. Static model and effect of loading are solved in software Scia Engineer. Reviews are calculated by hand according to current standards.

Footbridge across the expressway
Páleník, Petr ; Kocourek, Petr (referee) ; Nečas, Radim (advisor)
The aim of this master thesis is a design of the pedestrian bridge across the highway. The bridge is formed by a slab structure of 6 spans with lenghts from 9 to 51 m. The main spans are suspended on a V shape pylon. The deck of the span across the highway is assambled of precast segments and composite deck slab. The deck is in the lenghtways kept in the parabolic arch. The model of the construction is made in software ANSYS, the solution was done non-linear. The design and assessment are according to the europien standard.

Bridge over the Živný Brook
Sekanina, Josef ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
This thesis occupies with the design of the road bridge over the stream Živný, a railway lane and a projected road between Běleč village and Husinec village. There are designed three variants of bridges. The variant no. 1 – continuous box girded beam – was chosen for the detailed analysis. The pre-stressed concrete road bridge is designed and evaluated according to European standards – Euro codes. The sequential construction influence and its impact on the construction is also considered in the calculations. The drawing documentation and the visualization of the bridge are made.

Girder bridge over the Morava river
Pidima, Jan ; Klusáček, Ladislav (referee) ; Panáček, Josef (advisor)
Bachelor's thesis deals with a design of one-span road bridge on road II/446 over river Morava in the village of Hanušovice. Three possible designs were developed and from these the version with two post-tensioned girders was chosen. Structural model and load effects are solved in the the Scia Engineer 2014.0. Assesments are calculated in hand according to Eurocodes. Load effects from temperature, wind and horizontal effects from traffic are not taken into account.

Girder concrete bridge
Kubelka, Jan ; Klusáček, Ladislav (referee) ; Panáček, Josef (advisor)
Bachelor´s thesis is dealing with design of the road brigde on the road III/1219 over the river Lomnice. Three possible variants were developed, the chosen one is girder concrete bridge. A calculation has been done by hand, part of the thesis has been performed using Scia Engineer. Results were compared. The construction has been considered acconding to Eurocode.

Bridge over the Lomnice river
Klein, Vojtěch ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
The aim of this thesis is to design a bridge across the river Lomnice in Mirotice. It was designed in three variants. For detailed solving was chosen post-tensioned girder structure. Calculation of internal forces was made on the computational model in Scia Engineer 2013.1. The checks were counted manually in accordance with European standards.

Girder bridge over the Lužnice River
Vaculíková, Klára ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor thesis is the design of the bridge across the river Lužnice. The main topic is the design and calculation of the supporting single-span bridge construction. Three options were developed, the beam constructions and the variant of prestressed prefabricate beams. There was chosen the first option. The structure is post-tensioned. The static model and analysis of the structure has been performed using Scia Engineer 2012.0. Simplified calculations has been done by hand according to Eurocode. The calculation is made without the influence of creep, shrink and time analysis.

Girder bridge over the Lomnice River
Svoboda, Tomáš ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor´s thesis is the design of the ghrinder bridge over the Lomnice river. The main topic is static calculation of supporting construction of one span bridge. Two studies were executed and the second option, pre-stressed girder bridge was chosen. The supporting construction is 22 meters long. Static model and effects of loadings are solved the in software Scia Engineer. Reviews are calculated by hand according to current standards.

Únavové parametry betonu pro předepjaté vzorky
Seitl, Stanislav ; Juřinová, E. ; Keršner, Z. ; Bílek, V.
The paper presents values of basic fatigue parameters measured on three-point bending specimens of concrete for pre-stressed elements. These specimens are the most frequently used for fracture laboratory testing, especially of quasi-brittle cement-based composites. According to the regression technique, pilot Wöhler curve for predicting the fatigue life of pres-stressed concrete element is suggested. Keywords of the paper are fatigue/fracture parameters and cement-based composite
