Highway arch bridge
Vavřička, Lukáš ; Šopík,, Leonard (referee) ; Koláček, Jan (advisor)
The aim of the master thesis was a design of arch highway bridge made of prestressed reinforced concrete. In the beginning two versions of construction were designed, with box-girder and double-girder cross section of bridge deck, from which the variant of double-girder cross section in combination with box-girder arch were chosen for further detail postprocessing. The basics of the solution laid in right choice of dimensions of elements creating load-bearing system and construction geometry. Subsequently global beam model was created, which was used to prestress design and structural assessment of ultimate and serviceability limit states of pillars, arches and bridge deck during the building phases, service lifetime and in the end of lifetime of construction. For detail assessment, linear and nonlinear analysis was created using Midas Civil. To check the cross-sectional direction of bridge deck, slab model was made using Scia Engineer software

Behavior studies of the timber footbridges structures
Vitásková, Petra ; Brdečko, Luděk (referee) ; Zídek, Rostislav (advisor)
Master’s thesis „Behavioral studies of the timber footbridges structures“ deals with static models of timber footbridges. This thesis mainly consists of the behavioral study of historical timber footbridge in the village of Černvír in Vysočina. Based on the actual design of the bridge a three-dimensional beam model was created. This thesis also includes two contemporary alternatives of timber covered bridges. The individual structural elements were assessed according to the applicable standards. To analyze the model FEM program SCIA Engineer 2012 was used.

Static and modal analysis of bridge structure
Turková, Martina ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis is based on structural analysis calculated by Dopravoprojekt Ostrava company that was used for dimensioning of the oblique bridge structure No. 433 27-3, in Popůvky, Přerov district. The beam model which is part of static calculation and is designed by Nexis 32 software, served as ground. The aim of the thesis was to construct an identical beam model, specifying boardwall model and perform static and modal analysis. All calculation were done in Dlubal RFEM 5.01 software.

Static analysis of railway bridge
Bureš, Vojtěch ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis deals with the static analysis of a railway bridge. Using AxisVM X6 software, I created 4 different models and compared them not only with each other, but also with simple manual calculations. Two models are beam models, the third is shell model, the fourth is also shell but with an end ledge that reinforces the entire structure. The structures are loaded by a manually calculated load according to the standard.

Bridge ower railway line
Prekop, Michal ; Russnák, Adam (referee) ; Panáček, Josef (advisor)
Diploma thesis is focused on a design of the road bridge of the category S7,5 in cadastral territory of a municipality Polanka nad Odrou. Three preliminary studies have been proposed. Box girder beam with a slant walls were selected for more detailed processing. Construction of the bridge is going to be build by time-dependent analysis on a solid formwork. The calculation of load is done by using computer software Midas Civil 19 v 2.1. and Scia Engineer 19.1. Selected preliminary was assessed according to the recent Europan standards.

Reinforced concrete road bridge
Koumar, Jan ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The subject of this bachelor's thesis is the design of a reinforced concrete road bridge with one span over the river Oskava in the village Unicov. The bridge will convert road II/449 category S 7.5 / 50. Two shape variants of the cross-section were designed, from which a slab with a trapezoidal cross-section and a considered span of the bridge of 14.00 m was selected for the design and assessment of the load-bearing structure. The internal forces from the applied load were calculated on a slab model in SCIA Engineer 18.1 and compared with a manual calculation on a bar model using the method of resistive widths. The load-bearing structure is dimensioned for the ultimate limit state and the serviceability limit state.

Ultimita
Jindra, Daniel ; Kala, Jiří (referee) ; Hradil, Petr (advisor)
Structural beam and shell models were assembled in ANSYS program package. Design loads are defined according to Euro codes. Nonlinear analysis of structure has been established. Ultimate limit state of beams and cross sections were determined. Obtained results of ultimate limit state analysis were compared with Euro codes for design thin-walled steel structures.
