Static and modal analysis of bridge structure
Turková, Martina ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis is based on structural analysis calculated by Dopravoprojekt Ostrava company that was used for dimensioning of the oblique bridge structure No. 433 27-3, in Popůvky, Přerov district. The beam model which is part of static calculation and is designed by Nexis 32 software, served as ground. The aim of the thesis was to construct an identical beam model, specifying boardwall model and perform static and modal analysis. All calculation were done in Dlubal RFEM 5.01 software.

Static analysis of cable
Folvarčná, Ingrid ; Kytýr, Jiří (referee) ; Vlk, Zbyněk (advisor)
Subject of this thesis is to design the supporting rope of suspension bridge for pedestrians. The aim propose is the initial geometric shape of the rope and the rope load impressed upon the desired shape. The proposal will be carried out by hand calculation, which will be compared with the calculation in computing RFEM. To illustrate the behavior of the rope, the load will be carried out, but the rope will no longer be considered to limit states.

Automation of static solution of some wood structures problems
Hetver, Jan ; Vlk, Zbyněk (referee) ; Zídek, Rostislav (advisor)
The object of this work is to create a program with automatic design and assessment of joints with pin connections. The program uses procedures ČSN 73 1702 and the Johansen relations to calculate capacity. The program is particularly appropriate for saving time during a lengthy draft of these connections. It helps to easily assess connections to the ultimate limit state and serviceability.

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.

Wind load on truss high-rise structures
Komárková, Petra ; Vlk, Zbyněk (referee) ; Nevařil, Aleš (advisor)
This Bachelor´s thesis concerns wind load effects on truss high-rise structure. The aim is to describe response of lattice tower on effects of mean wind load, fluctuations and vortex shedding action. Further problem includes an influence of rime on aerodynamic characteristics of profiles. The structure is performed by means of computing software ANSYS. In the theoretical part there are procedures describing how to determine load on structure and basic theory of calculation. Then the applied part follows the theoretical one and describes operations in ANSYS.

Material nonlinear static response of civil structures
Kinclová, Radka ; Vlk, Zbyněk (referee) ; Nevařil, Aleš (advisor)
The aim of this bachelor’s thesis is the non-linear elastic and plastic response of the simple beam structures. Also the problematics of the plastic hinges development is adressed. This thesis will then describe the origin and magnitude of the residual stresses caused by welding. Ideal elastic-plastic behavior of materials and elastic behavior with strenghtening will be used to determine the limit load capacity of the simple structures and will be compared to solution in the ANSYS software.

Static analysis of clarified tank structure
Kika, Aleš ; Vlk, Zbyněk (referee) ; Hradil, Petr (advisor)
The aim of bachelor thesis was to perform static analysis of the retention tank. It was created a computational model of the construction in program ANSYS, defined all load cases, and their combinations. At the end of thesis, some components of the tank were designed and evaluated for ultimate limit state and service limit state.

Nonlinear Response of Steel Structures on Statical Loading
Nezbedová, Anna ; Vlk, Zbyněk (referee) ; Kala, Zdeněk (advisor)
This paper deals with the nonlinear response of steel structures to static loads. There are formulas derived for nonlinear analysis compressed, bended and tension members. By compressed elements, there is described the issue of buckling, by the bended, it is lateral-torsional buckling and tension elements are cables. As an example there is an calculation of a suspension two spans pedestrian steel bridge under load action of asymetrical loads. As another possible calculation process, the finite elements method is described.
