Reverification of the roof structure of St. Catherine church in Kateřinky
Bayer, Petr ; Balázs, Ivan (referee) ; Pešek, Ondřej (advisor)
Church of St. Catarine is located in Opava-Kateřinky, Kostelní 119/1. Due to the extensive damage to the truss structure, a survey was conducted focusing on the geometry of individual elements and their harm (extent of cracks and incidence of woodworm and mold). On the basis of the data obtained, a control calculation of truss elements above the main part of the church was performed (ultimate limit state (ULS) and the serviceability limit state (SLS)). Most elements were found to be satisfactory. However, replacing the most damaged parts of the elements is necessary.

Static analysis of suspension bridge variants
Zavřelová, Michaela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor's thesis deals with the static analysis of individual models of suspension footbridges. A manual calculation of the cable was processed. The actual position of the cable was determined by calculation. The manual calculation was compared with the RFEM calculation program. Furthermore, the models were loaded with manually calculated loads. The bachelor's thesis deals with the influence of pylon deflection on the global deformations of cable and bridge deck during individual load cases and combinations. For one of the models, the optimization of construction was processed.

Dynamic analysis of structure with seismic loads
Šnajdárková, Jana ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
This thesis focuses on creation of two models of high-rise construction - beam and shell. A dynamic analysis is performed on these models. The selected program is RFEM software and the created high-rise construction is Hearst Tower skyscraper, which is interesting for its diagrid system around its perimeter. There is described process of creating both models and associated problems. Dynamic analysis is performed using standard EN 1998-1. There belongs calculations of sufficient number of modal shapes, spectral analysis and time analysis. Then the results are compared on selected point on the both models.

Static analysis of the cylindrical tank
Frimlová, Eva ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis describes structural analysis of cylindrical tank. The goal of this thesis is creating a computational algorithm in a software called MATLAB, using which the structural analysis on idealized models of cylindrical tank is solved. These models are the rod model and the model with plane elements. This bachelor thesis is divided in several parts. Firstly, there is defined the structure, material and load of cylyndrical tank. Second part is about rod model, stiffness method and the calculation using this method. Next part is about model with plane elements, finite element method and its calculation. In the last part, there are results from each part and their comparison.

Study of impact of a transport vehicle into a structure.
Sychrová, Šárka ; Salajka, Vlastislav (referee) ; Němec, Ivan (advisor)
Master's thesis deals with the analysis of the impact of transport vehicle on a building structure. Transport vehicle is represented by an airliner and building structure is represented by a containment of a nuclear power plant. The aim of thesis was to explore the possibility of numerical simulation of an impact of transport vehicle on a building structure utilizing the RFEM program and evaluation of the damage extent.

Dynamic analysis of bridge construction
Kinclová, Radka ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
The objective of this diploma thesis is a dynamic analysis of a cable-stayed walkway. The RFEM structural analysis software is used for the calculation. Design principles of the structure are explained and analysis of the construction phases is then performed. The eigenmodes of the structure are calculated for various material combinations. The thesis examines the effects of moving loads and earthquake effects using several different methods. A comparison of the various loading effects on the structure and also the calculation methods is presented at the conclusion.

The influence of the magnitude of normal forces on nonlinear seismic analysis
Holiš, Ondřej ; Lang, Rostislav (referee) ; Vlk, Zbyněk (advisor)
The thesis is focused on studying the influence of the magnitude of normal forces and loads on the nonlinear dynamic analysis. Pushover method and nonlinear time history analysis were used to solve these problems. A number of numerical models with different nonlinearities and progressively increasing loads have been developed. The results were then compiled into graphs and tables for comparison. RFEM 5, RFEM 6 and a program in Python were used for the calculations.

Static analysis of the roof
Hořínek, Josef ; Vlk, Zbyněk (referee) ; Martinásek, Josef (advisor)
The Bachelor Thesis focuses on a static analysis of a timber roof truss. This roof trust is part of the saddle roof on the family home. The load on the structure is calculated manually according to valid standards. The load is divided into a total of 11 load cases. The calculation model of the structure is created in RFEM. Results of internal forces and deformations are checked by manual calculation using methods for statically indeterminate structures. These values are compared at the end.
