Solution of timber hall structures
Šigutová, Petra ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
The subject of my thesis is a static analysis of a different trusses of a great span length. The preface is devoted to the trusses their creation of plane models of a girder with the extent of 18 metres. The questions of construction´s joints are mainly solid. The conclusion is dedicated to the creation of the girder and joints´ formation.

Behavior studies of the timber footbridges structures
Vitásková, Petra ; Brdečko, Luděk (referee) ; Zídek, Rostislav (advisor)
Master’s thesis „Behavioral studies of the timber footbridges structures“ deals with static models of timber footbridges. This thesis mainly consists of the behavioral study of historical timber footbridge in the village of Černvír in Vysočina. Based on the actual design of the bridge a three-dimensional beam model was created. This thesis also includes two contemporary alternatives of timber covered bridges. The individual structural elements were assessed according to the applicable standards. To analyze the model FEM program SCIA Engineer 2012 was used.

D - Areas Analysis using Strut and Tie models
Konárek, Lukáš ; Hradil, Petr (referee) ; Zídek, Rostislav (advisor)
The objective of bachelor thesis is the analysis of typical D-areas of reinforced concrete structures. The analysis is performed using methods replacement truss. In the beginning models replacement truss are used for analysis shear bending girder. It is also shown in the individual chapters specific D-areas using spare truss method. These particular truss models are solved by RFEM program operating on the principle of Finite Element Method.

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.

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.

Study of steel frames behaviour depending on stifness of joints
Svoboda, Radek ; Brdečko, Luděk (referee) ; Zídek, Rostislav (advisor)
Bachelor’s thesis „Study of steel frames behaviour depending on stiffness of joints“ deals with real joint stiffness calculation by component method and compares its influence on steel construction behaviour computed by linear computational model in assessment of the first and the second limit state. Results are determined via computational modelling in FEM software, where are included individual joints – rigid, semi-rigid and joint. In the introductory part of the thesis is included analytical joints stiffness calculation according to standard ČSN EN 1993-1-8. In the second part the joints are designed to bear inner forces and moments, which created by load combination effects.

Study of static behaviour of selected agricultural objects
Horský, Vojtěch ; Zídek, Rostislav (referee) ; Brdečko, Luděk (advisor)
This thesis deals with the study of static behavior of agricultural buildings, evaluating their existing state using two-dimensional and three-dimensional construction models. Elements that serve to improve static effects of constructions are implemented into these models or replace the currently used elements. Strains of the modified constructions are calculated are applied to qualify the implemented elements and designed joints.
