Study of dynamic effect on a bridge structure with moving loads
 Zavřelová, Michaela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The goal of the master thesis is a dynamic parametric study on the dynamic effects of high-speed train using the HSLM-A load model on a railway bridge. The calculation model is processed, in RFEM 5.29.01 with RF-MOVE module and prerelease versions RFEM 6 and RSTAB 9, as a 2D member in the XZ plane. Furthermore, static load cases and load models LM 71 and HSLM-A are created. The HSLM-A load model is processed for universal trains A1-A10, which each cross the railway bridge at a total of 15 speeds ranging from 120 km/h to 400 km/h. A detailed parametric study of the dependence of the maximum deformation and acceleration in the Z direction on the speeds of each train set is performed. Modal and time history analysis is used in the parametric study. Part of the work is to determine the resonance region.
