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.

Development of algorithm and pertinent program mogule for statical and dynamical analysis of cables on pulleys
Štekbauer, Hynek ; Hradil, Petr (referee) ; Němec, Ivan (advisor)
The goal of this master thesis is to develop an algorithm for solving cables on pulleys, which would be more efficient and accurate than existing algorithm used in software RFEM. This algorithm was integrated to the program for static and dynamic analysis of structures, in the form of particular program module. This work also contains examples of using this algorithm. The comparison of expected results with outcomes from the program is presented. The suitability for common practise is examined based on this comparison. The examples showed that the new algorithm for solving of cables on pulleys is more powerful and more accurate than existing solutions and most likely does not has equivalent competition.

Static analysis of flexibly supported on structures
Šnajdárková, Jana ; Brdečko, Luděk (referee) ; Vlk, Zbyněk (advisor)
This work focuses on comparing the static analysis on the various types of models. It is calculated as manual calculations and in software RFEM. Without use of the software are created simplified beam model on fixed and flexible supports and to them are calculated support reactions, shear forces and bending moments. One part focuses on the calculation of the reduction of bending moments, to achieve more accurate results. In the program are created models of rod and models of space, which are composed of surfaces. There is also created a model of the split rod to form a reduction of the bending moments over the supports. The last model is a beam with two separate chambers, which are fixed to the plate and defined as ribs which cooperates with the plate. Internal forces on all models is then compared.

Ceiling construction with prestressed girder
Skuhravý, František ; Klusáček, Ladislav (referee) ; Perla, Jan (advisor)
The bachelor’s thesis process design of floor structure, which consists continuous cast-in-place reinforced concrete slab with three spans. The slab is supported by post-tensioned flat beams. These are pin-supported by pillars on outer edges, inner supports are ensured by columns. Comparison of the options of prestressing reinforcement with and without bond precedes designing of the beam itself. Based on its results a suitable option is chosen and then applied on a whole structure.

Design of steel-concrete arch structure of footbridge over the river Svratka
Vraňanová, Veronika ; Marván, David (referee) ; Nečesal, Petr (advisor)
The main goal of this diploma thesis was to project a design of arch bridge‘s framework over the Svratka river. This single-span bridge has the span of 52,5m. The framework is constructed from a pair of beams, suspended from the pair of beams bent towards each other. The bridge deck is coupled with steel crosspieces. The construction design was executed in computing programme Dlubal RFEM 5.07. The individual components of the framework were assessed in Microsoft Excel. The calculation considered the load of wind and pedestrians’ movement and their effect on the dynamics of the construction. The phases of development were also considered. Assessments of coupled cross-section, main beams of steel construction, tension systems and selected construction joints were executed in a static calculation. Moreover, a design of a bearing and a bridge plug joint. Finally, a drawing documentation and a final report were prepared in regards with the requirements. The construction design and its assessment were executed according to valid standards.
