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.

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.

Stability problems study of framed structures
Piják, Jiří ; Vlk, Zbyněk (referee) ; Zídek, Rostislav (advisor)
In the first chapter the problem of ideal member, member with initial curvature and meaning of Euler’s critical force is regarded. Parameters of stability, mainly calculation of critical loading and buckling lengths, are studied in the second part. The same part contains comparison of results of computational programs and mechanical approach. Next attention is paid to imperfections, to possibilities of determination and comparison of results on a simple member. Comparison of possible judgements of buckling on a simple beam and on frames according to ČSN EN 1993-1-1 is performed on the final part.

London Eye
Hušek, Martin ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
Performance of static analysis of the London Eye structure is the subject of this diploma thesis. First chapters of the thesis analyses overview of realized structures of the Ferris wheel. The main part of the thesis analyses the London Eye structure itself. Specifically are described response analyses, sensitivity analyses, analyses of ultimate limit state and serviceability, stress analyses, analyses of fatigue stress and lifetime analyses. The thesis describes among static analysis also a design of dynamic vibration absorbers. The results of each analysis are evaluated in the final chapters.

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.

Some aspects of reinforced concrete slabs
Bartosch, Václav ; Vlk, Zbyněk (referee) ; Zídek, Rostislav (advisor)
The topic of this bachelor thesis is a simple reinforced concrete ceiling construction which has a rectangular ground plan and it is locally supported by square columns. Plane models of the same board but with different types of support are made. The board is calculated by the classical method of summary moments to be checked and compared the results. The work focuses mainly on the process of bending moments at the point of support. Waveforms of moments in the adjoining fields are listed here for completion. The results of static models are compared with the results of the summary moments method. The final part of this work is focused on the waveforms of moments after the formation of cracks.

Steel Structure Analysis
Nováková, Ľubica ; Hušek, Martin (referee) ; Zídek, Rostislav (advisor)
This diploma thesis is engaged by analyses of steel structure. Structure was modelled in two variants, in software ANSYS Mechanical. Both models were at first counted by linear analyses, then they were counted by non-linear analyses. At the end models were counted by modal analyses. Aim of the study was evaluated and decide, which one of variant is structurally and economically most competently. Selected model was assessed on ultimate and serviceability limit state.
