Stability solution of framed structures
Baxant, Radek ; Brdečko, Luděk (referee) ; Zídek, Rostislav (advisor)
This diploma thesis deals with the subject of slenderness bars’ stability assessment, especially in the steel structures. Before the assessment of bars in the frame constructions, we search for the influence of the computational model’s settings on the final result. The initial geometrical imperfections are examined on the model of Euler’s bar. The influence of the rigidity of girders on the poles’ buckling length is examined on the basic frame construction. The buckling lengths are assessed in the comparison with the figures we got from the statistical tables and the computational software. The influence of construction’s initial tilt and its replacement by the system of outer forces is examined on the frame structure. Three-hinged frame structure with variable cross-section member is designed then and the influence of non-linear calculations on the inner forces is studied. In the complex frame assessment, the influence of the number of parts of variable cross-section member on the bars’ buckling length is examined.

Behavior of traditional carpentry structures
Šafránková, Lucie ; Brdečko, Luděk (referee) ; Zídek, Rostislav (advisor)
Bachelor’s thesis “Behave of traditional carpenter structures“ analyzes the behavior of traditional timber roof trusses. Based on the actual design of roof trusses tree-dimensional computational models are created, individual structural elements are assessed on the first and second limit state and one connection are considered. For the analysis of planar and tree-dimensional model programme SCIA Engineer 2011.1. is used.

Analysis of traditional timber structures
Šigutová, Petra ; Vlk,, Zbyněk (referee) ; Zídek, Rostislav (advisor)
The subject of my bachelor´s thesis is the research of the statistical effect of a barn´s rafter. The preface is devoted to the creating two - dimensional models of the basic types of the rafters and their behavior during the loading. The main part of my thesis deals with the composing three-dimensional models of the roof. I try to depict the behavior of the structure after the deformation of the joints. I compare the results to the real behavior of the structure.

Static Analysis of certain types of timber structures
Čáslavová, Sandra ; Brdečko, Luděk (referee) ; Zídek, Rostislav (advisor)
This bachelor thesis is focused on analyzing a timber roof trusses, identifying and evaluating differences in their behavior. The thesis is aimed to review conventional trusses, create plane models which are then compared with each other. From selected truss was used to create a 3D model, on which are key joints are reviewed. Scia Engineer 15.2.140 program is used to create an expert opinion. This program is based on FEM principle.

Design and Analysis of Structure of Spherical House
Kolodzej, Ján ; Zídek, Rostislav (referee) ; Frantík, Petr (advisor)
This bachelor thesis is dedicated to designing of two different versions of the construction for a spherical house. The design was developed upon an interest of the investor, with whom were both versions also consulted and is supposed to lead to an actual project and realization. The two versions will differ in usage of building materials and the construction geometry.

Design and static analysis of the sports hall roof
Chudějová, Ludmila ; Zídek, Rostislav (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis deals with design and static analysis of sports hall roof. The program Dlubal RFEM 5.11 were created models of plane frames and calculated using the finite element method. These models were compared with each other. The values of internal forces were taken from RFEM program. Subsequently, one of the load cases was verified by manual calculation.

Static analysis of the roof structure
Uherek, Jan ; Zídek, Rostislav (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis deals with the static analysis of the wooden roof structure – truss. In SCIA Engineer 17.1, which works on the finite element method, were created spatial and planar design models, and were compared them with each other. From the program were used informations about the internal forces in the struts, their deformations and after that their assessments were carried out.

Design of Automation of Some Steel Structures Elements
Kopeček, Josef ; Brdečko, Luděk (referee) ; Zídek, Rostislav (advisor)
The aim of the presented thesis is to create a program for automatic assessment of bolted and welded connections. The program uses procedures mentioned in the ČSN EN 1993-1-8. The comparison of the program is verified by the comparison of suitable chosen examples of analytical solution. The purpose of the program is to make the draft of bolted and welded connections more efficient.

Static analysis of the roof structure
Dolníčková, Andrea ; Zídek, Rostislav (referee) ; Vlk, Zbyněk (advisor)
The thesis is focused on a static analysis of a roof truss with a steel purlin. It is a pitched roof of an L shaped groundplan. Computational model of the structure is carried out in the RFEM 5.07 software tool, which performes calculations using the Finite Element Method. There are 14 load cases applied on the model of the structure. The variable loads were determined according to ČSN EN 1991-1. The individual load-bearing elements are assessed for an ultimate as well as for a serviceability limit state. The assessments are processed by a hand calculation and verified by an assessment of the structure performed in the additional software modules RF-TIMBER Pro and RF-STEEL EC3. In the last part of the thesis there are some specific joints of the elements defined.

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.
