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.

Static analysis of flexibly supported on structures
Šnajdárková, Jana ; Brdečko, Luděk (referee) ; Vlk, Zbyněk (advisor)
This work focuses on comparing the static analysis on the various types of models. It is calculated as manual calculations and in software RFEM. Without use of the software are created simplified beam model on fixed and flexible supports and to them are calculated support reactions, shear forces and bending moments. One part focuses on the calculation of the reduction of bending moments, to achieve more accurate results. In the program are created models of rod and models of space, which are composed of surfaces. There is also created a model of the split rod to form a reduction of the bending moments over the supports. The last model is a beam with two separate chambers, which are fixed to the plate and defined as ribs which cooperates with the plate. Internal forces on all models is then compared.

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.

Static solution of timber structure
Burza, Martin ; Zídek, Rostislav (referee) ; Brdečko, Luděk (advisor)
The Bachelor thesis is focused on an analysis of a wooden house truss. The first part deals with the load acting on spatially complex roof structure which is modeled in the Scia Engineer 2012 analysis software. Furthermore, the work considers the most stressed cross sections of wood elements and selected joints. In conclusion, the Bachelor´s thesis evaluates the original construction design.

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.

Design and assessment of reconstruction of historical timber structure
Nováková, Ľubica ; Zídek, Rostislav (referee) ; Brdečko, Luděk (advisor)
Bachelor’s thesis “Design and evaluation of rehabilitation of historic timber structures” is engaged in design and evaluation new replacement elements – proteases. It solved also design and evaluation connections between new and original elements. Proteases are designed, because of damage historic timber structure in complex Castle Žehušice. On the basis of project documentation is created computational model of characteristic structure section. Connections and new elements are assessed on the first limit state – Ultimate limit state. For the analysis computational model is used program SCIA Engineer 2012.

Design and assessment of the timber dome
Hušek, Martin ; Zídek, Rostislav (referee) ; Brdečko, Luděk (advisor)
The subject of the bachelor thesis is design and assessment of the timber dome. The opening chapters are devoted to design geometry of dome itself with focus on its modification for the purpose of the shape and structure optimizing. The following chapters describe the structural design details and overall attitude to the issue. The final chapters value custom design structures, compare alternatives and provide answers to questions formed in the thesis.
