Static analysis of moving skyscraper
Jedlička, Michal ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The thesis is about static analysis of moving skyscraper (inspired by The Dynamic Tower). There is a rotation of each particular floor around its axis independently on each other. In this thesis, moving skyscraper is solved as a whole piece with specialization in the moving floors and their mounting on the core of the building.

Static analysis of wooden truss
Cicálková, Eliška ; Zídek, Rostislav (referee) ; Vlk, Zbyněk (advisor)
Bachelor work is processed as static calculation of traditional wooden roof. For analysis of structural model is used program using finite element method (FEM) - Dlubal RFEM 4. According to the actual implementation is modeled brace calculating model. Here separate construction elements are assessed the first and the second limit states - ultimate limit state and serviceability limit state. Nail connection is maked at the close of work. It´s connections of roof tie and rafter.

Dynamic analysis of railway bridge
Mojrová, Martina ; Vlk, Zbyněk (referee) ; Nevařil, Aleš (advisor)
The content of work is to determine modal characteristics of bridge construction over the Dyje river near Břeclav. That is done in ANSYS software and AxisVM software. These characteristics are compared with results from dynamic loading test and they are compared between themselves. In thesis is also an assessment of response to static traffic loads because of decision about dynamic analysis necessity. Then there is a simulation of dynamic traffic loads and results of this simulation are compared with results of dynamic analysis which was done by the project. The aim is to do a few static and dynamic tasks and compare results with the real dynamic test and with calculated results and to determinate the effect on certain variables.

Dynamic analysis of structure loaded seismic loads
Janošková, Lenka ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
In this diploma thesis the seismic load on two different models is solved – the first model is a beam hall and the second model is a multistory building. The calculation of seismic load was performed according to standard ČSN EN 1998-1 (Eurocode 8) using the response spectrum analysis and the method of equivalent static forces (substi-tute load). For the combination of seismic responses in different directions are used SRSS and CQC rules. Models and calculations were solved in a student’s version of program RFEM 4.10 (Ing. Software Dlubal, s.r.o.). The comparison of mentioned methods in each models, also the comparison of combinative rules in calculation and the final evaluation of seismic responses on both of models are the subject of this thesis.

Analysis of structure using stages calculation
Čejková, Eva ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
Bachelor thesis deals with the roof structure, its static assessment and analysis phases of construction. It is a roofing tennis hall parabolic trusses, which are formed from steel. In the hall there are three tennis courts and space for an auditorium for spectators. The entire structure and calculations are processed in a static software RFEM by the Dlubal. Only the load cases are calculated manually.

Optimization of parameters of dynamic relaxation in solving plastic limit states of structures
Poláček, Milan ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
The aim of the thesis is to create an analytical model of frame construction. Determining load at which individual plastic hinges are formed until the collapse of the structure. The analysis is going to be performed by RFEM with an additional module RFDYNAM. Subsequently, the parameters of dynamic relaxation is going to be optimized to specify and speed up the calculations. Finally, the optimized parameters is going to be used to analyze the storeyed frame construction formed Ing. Jan Vales including a comparison of findings.

Dynamic analysis of structure loaded seismic loads
Šulerová, Zdeňka ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
This thesis deals with the calculation of response of reinforced concrete construction on the effect of seismic tension. Time and spectral analysis were made. They are mentioned as possible ways of calculation in EN 1998 - 1:2004 norm. Final figures of global deformations and stress on selected beam from the time and spectral analysis were firstly compared for the horizontal components of seismic stress affecting only in one direction. Subsequently comparison of time progress to combination of these effects mentioned in relevant norm was made. In the conclusion the results of used analysis are appraised.

Design of Steel Structure
Svoboda, Radek ; Vlk, Zbyněk (referee) ; Zídek, Rostislav (advisor)
Topic of the master’s thesis is design and assessment of steel construction of the industrial building used to glass sand treatment. The building has the top view dimensions 12,0 x 12,0 m and roof ridge height 15,6 m. Disposition if the individual elements was designed according to conditions of the technology and production process. The thesis focus on creating of computational model and assessment to ultimate and serviceability limit states of individual elements. Further thesis contains of design and optimisation of some joints.

Static analysis of joints in timber structures
Řehová, Jana ; Vlk, Zbyněk (referee) ; Zídek, Rostislav (advisor)
This bachelor thesis concentrates on the analysis of behaviour of carpentery joints in wooden constructions. Mainly it focues on sloped anchorage and hinges. The seams were analyzed classicaly by their statical influence and normative recommendations. The SCIA Engineer software was used for the analysis of the sloped anchorage.
