Jankovičová, Soňa ; Lang, Rostislav (referee) ; Martinásek, Josef (advisor)
The subject of this diploma thesis is static and dynamic analysis of the load-bearing steel structure of footbridge with reinforced concrete bridge deck, standing over the Morava river. Bridge was designed as a solid ribbed arch, so it consists of a pair truss beams, strengthen by two steel arches with suspenders. There were created two different models, one in program SCIA Engineer, where the individual elements were designed as spatial bars. In the second model, they were created as surface elements. For such model, it was more appropriate to use ANSYS Mechanical APDL program. The load and selected combinations are calculated manually according to valid national standardization documents. Furthermore, this thesis contains manual calculations of stress. The results are compared with computing programs to determine the correct functioning of the models. In the next part, the work is devoted to static and dynamic analysis, where it compares the results of the mentioned two model situations.
