Study of joints of frame steel structures
Cikánek, Ondřej ; Hušek, Martin (referee) ; Zídek, Rostislav (advisor)
Master's thesis „Study of joints of frame steel structures“ examine certain analysis types of frame steal joints, which are analysed both by component method and by specialized software IDEA RS. Obtained results are compared by both methods, in terms of load-bearing capacity and in terms of stiffness. Theoretical joints stiffness calculation according to standard ČSN EN 1993-1-8 is included in the introductory part of the thesis. In the second part, joints are designed to bear inner forces and moments, which were created by load combination effects and then analysed.

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.

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.

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.

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.

A Guesthouse with a Restaurant
Vít, Lukáš ; Zídek, Rostislav (referee) ; Skála, Jiří (advisor)
The project deals with new building of guesthouse and restaurant in Křídla. This work aims to develop design documents for building construction. Guesthouse is for 41 guests. The part of the guesthouse is restaurant. The building has 2 above-ground floors and basement. The building is based on brick system Porotherm. The guesthouse and restaurant has a flat roof. The building is situated on slightly sloping terrain.

Design and Assessment of Timber Structure
Končák, Jiří ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
Subject of my masters's thesis is bearing construction from wood of pedestrian bridge via river Bečva in Karolinka. Span of the pedestrian bridge is 37 meters. Three 3D models of global model of whole construction and support models are created. The resulting draft is worked up in details. This work aim on models of joints of wooden parts, boundary conditions and global function of static model.

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.

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.
