Highway box girder bridge
Ondrůšková, Kamila ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The subject of the diploma thesis is the bridging design of the valley and Doľanský potok on the D1 motorway in the section Jánovce - Jablonov in Slovakia. Three variants of bridging have been designed and then compared. A post-tensioned construction of the box girder cross section was chosen as the most suitable variant, which was further checked. The static calculation was drawn up according to European standards.

Dynamic analysis of track
Mojžíšek, Dominik ; Salajka, Vlastislav (referee) ; Plášek, Otto (advisor)
The diploma thesis deals with descriptions of vehicle - track dynamic interface. There are described basic analytical models of railway track. The numerical models are created by using finite element methods with moving load simulated axle of rail vehicle. The aim of thesis is to create the model which most accurately describes the dynamic phenomena in the track. The results from models are compared with data obtained by measuring in the track. Next aim of thesis is to determine dependency of rail cross-sectional characteristics on equivalent rail head wear and then on rail deflection.

Determination of geometric characteristics of curved beam
Foukal, Jakub ; Houfek, Martin (referee) ; Benešovský, Marek (advisor)
This bachelor thesis focuses on creating a algorithm for determining geometric characteristics of curved beam. In the first part, formulas are taken from technical literature. These formulas are then modified and used for implementation of algorithms. In the following section, there are two algorithms for determining the curvature of a curved beam and comparison between their calculated values. The concluding part focuses on an algorithm for calculating the cross-section characteristics from random image format. The algorithm of cross-section characteristics is analytically verified.
