Design of a railway bridge with an extremely compressed construction height according to MVL 115
Svoboda, Petr ; Šoukalová, Gabriela (referee) ; Kožik, Libor (advisor)
The aim of the thesis was a static and economic comparison of three variants of railway steel bridges with extremely compressed construction height according to the Bridge Model List (MVL) 115. A 3D model was created in RFEM for all variants. The bridge alternatives were evaluated for permanent loads, loads from rail traffic, and other significant loads. The option that came out best in terms of cost was then reassessed in more detail as part of a separate structural calculation.
Shape optimization of the typical frame of the load-bearing structure of the steel hall
Kuzbová, Šárka ; Vlk, Zbyněk (referee) ; Hokeš, Filip (advisor)
The thesis deals with the shape optimization of a typical frame of a steel hall structure. The calculation is performed for two types of parametric models created with both 1D and 2D finite element models in RFEM 6. The aim of the optimization process is to achieve a state where the structure has the lowest mass while satisfying the stress limit. The first model, which is created using 1D finite elements, focuses on optimizing the initial and final section heights of the members with the raises. The following model, which is developed using 2D finite elements, is aimed at optimizing the openings of the pierced beam. The thesis also includes analytical verification of the model using the deformation method.
