Modeling of accidental torsion and its effect on spectral analysis
Šulerová, Zdeňka ; Nevařil,, Aleš (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis deals with the appraisal of concrete frame structures in seismic loadeffects. To calculate the simplified method will be used to support lateral forcesspecified in EN 1998-1:2004 - Design of structures for earthquake resistence. The calculation will be done by manual calculation and the calculation program RFEM. These alternative methods will be calculated loads and torques acting on the structure and subsequently compared. The main part of the bachelor's thesis is to evaluate the effects of the random distribution of mass,prescribed by the standard, and our chosen mass distribution, where we expect the maximum deformation.

Analysis of the structure for the effects of earthquakes
Švejcar, Martin ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
This master thesis deals with analysis of a selected construction subjected to a seismic load. In the Dlubal RFEM programme, a basic model was created and analyzed with the spectral analysis using response spectra and with the time analysis using accelerograms from the database of the programme. The outcomes from these analyses were compared. Subsequently, the same calculations were performed on modified models and the results of the internal forces and deformations of the structure were compared with the outputs obtained on the original basic model.

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.
