Static analysis of the sports hall roof
Meissnerová, Sabina ; Hokeš, Filip (referee) ; Vlk, Zbyněk (advisor)
The final thesis deals with structural analysis of the roofing of the sports hall. Computational model was created in the computational software Dlubal RFEM 6.04 according to the provided documents. The loads were performed in accordance with valid standards and the structure was assessed for the ultimate and serviceability limit state. Manual assessment calculations were compared with the software. The final thesis deals with the manual calculation of internal forces on a curved beam from the self-weight of the structure and the stability of the structure is demonstrated first on a single-sided fixed beam and then on the created spatial model.

Analytical Design Optimization of a Structure
Šubíková, Magdaléna ; Vlk, Zbyněk (referee) ; Hokeš, Filip (advisor)
The bachelor thesis deals with an analytical optimization of the construction design. Designed structure was inspired by a steel structure of the Bernard lookout tower. The analytical optimization was performed on a partial model of the structure and static analysis was obtained using the direct stiffness method. Two models for optimization were created in Scie Engineer 20.0 – one partial, the other complete. The impact of the optimization on the mass and cost of the structure was assessed.

Static and dynamic analysis of Prestressed bridge structure
Hokeš, Filip ; Nečas, Radim (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to perform static and dynamic analysis of prestressed concrete bridge structures in computational system ANSYS. For the analysis was chosen footbridge over the river Svratka in Brno. In relation to this topic are solved various types of modeling prestress at a finite element level. Before analyzing the footbridge is analyzed in detail the static system and the corresponding final geometry of the structure. Knowledge of the functioning of the static system is used to build the computational model of the structure, on which is subsequently performed static and dynamic analysis.

Static analysis of the prefabricated hall
Holiš, Ondřej ; Hokeš, Filip (referee) ; Vlk, Zbyněk (advisor)
This thesis is aimed at the calculation of inner forces and deformations of three-aisled, one-storey, industrial hall. For the structural analysis the integration of the elastic curve method has been used along with Mohr´s method for calculation of deflections. The problematics of sloped beams and their influence on the structural behaviour of the construction has also been included in this thesis. For the calculations and diagram plots the programmes such as SMath and MathCad have been used.The results have then been compared with multiple planar models of the construction made in the RFEM 6.02 programme.

Design and static analysis of the lookout tower
Řehořová, Alena ; Hokeš, Filip (referee) ; Vlk, Zbyněk (advisor)
The topic of the bachelor's thesis is the design and static analysis of the steel structure of a lookout tower with a total height of 25.32 meters. The floor plan of each floor is a regular hexagon with a decreasing diameter to the center of height. The main viewing platform is located at a height of 24 meters, other viewing platforms are located in quarters of the height. The aim of the work is to design various structural solutions and their comparison, with respect to the effects of loading on the structure and its parts. The static model and calculation of internal forces is performed in the student version of the SCIA Engineer 20.0 program.

Shape optimization of civil engineering structure
Kuzbová, Šárka ; Vlk, Zbyněk (referee) ; Hokeš, Filip (advisor)
The bachelor thesis is focused on shape optimization of a selected load-bearing structure. The calculation is carried out in RFEM 6. The desired goal is to achieve an optimum state where the structure has the lowest mass and at the same time satisfies the ultimate and serviceability limit state. The optimization procedure of the selected structure is focused on optimizing the position of the diagonals. The bachelor thesis also includes a study of the shape optimization of the simplified statically certain and uncertain structure.

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.

Particle swarm algorithm in problems of structural optimization
Šubíková, Magdaléna ; Lang, Rostislav (referee) ; Hokeš, Filip (advisor)
The thesis deals with the application of the nature-inspired stochastic particle swarm algorithm to the structural optimization problem in the Dlubal RFEM computing system. A sensitivity analysis of input parameters and optimization using PSOA was performed on a parametric member model of the steel structure of the Holedná tower. The main contribution of this thesis lies in the analysis of a specific algorithm configuration and its ability to effectively find the global minimum of the chosen objective function.
