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 Precision of the Stability Analysis
Sotulář, Jiří ; Pilgr, Milan (referee) ; Hron, Lukáš (advisor)
The thesis deals with the precision of the stability analysis of the pressed member. The loss of stability of the bukling is determinate by using several metods, which are compared each other. The thesis is partitioned into three parts that works together. The first part deals with the theory of analysis of the buckling stability. Here is described the gradual solution of analytical analysis for real beam and here is described the final compared for ideal, imperfekt and real beam too. It is also short solved buckling by using software. In the second part is compared by using computing systems and anylitical analysis for several basic buckling systems. The results of the compared are summarised in the final graphs and tables for each solved element and systems. In the third part are designed and static checked load-bearing element of steel storage hall. The buckling beams are checked by using findings from the previous analysis.

Stability analysis of slender high-rise strucutres
Nevřalová, Jana ; Vlk,, Zbyněk (referee) ; Nevařil, Aleš (advisor)
The work focuses on static analysis of simplified models and their mutual comparison of selected high-rise building. Attention is paid to the differences in the geometry of each model and the influence of model dimension (bar or planar or spatial) of individual building parts. For selected high-rise construction are finally assembled four finite element models. It is examined the issue of stability of slender high-rise building and compared the differences between the results of simplified models.
