Static design of roof structure
Duda, Tomáš ; Bažant, Zdeněk (referee) ; Zich, Miloš (advisor)
The subject of the diploma thesis is the design and static analysis of roof structure. It is prestressed roof shell (membrane) supported by a cable. The whole thesis is divided into several separated units according to task's specification. The text section describes the introduction to the issue of presstressed suspension cable constructions and displays their possible shapes, types and realizations. There is also technical report of solved shell, which was written on the base of the documents, drawn drawings and structural (static) analysis.

Research in the field of construction elements and design of concrete pavements
Grošek, Jiří ; Birnbaumová, Marie (referee) ; Vébr,, Ludvík (referee) ; Varaus, Michal (advisor)
The presented dissertation is focused on research in the field of dowels and design of concrete pavements using the finite element method. The theory part describes the history and the currently used techniques in the world and in the Czech Republic. The practice part of the dissertation contains a description of design methods, diagnostics of concrete pavements by using FWD and a description of laboratory tests on beams with inserted dowels. The results of measurements and modelling are verified on real operating conditions on testing fields. Based on the dissertation results, the amendment of the Czech standard ČSN 73 6123-1 regarding the position of dowels were proposed and approved. In addition, methodological guidelines of the Ministry of Transport regarding the measurements of the dowels and tie bars position and diagnostic by FWD was approved. The conclusion of the work summarizes and emphasizes the results of the dissertation.

Significance of tensile stresses in a bended beam with constrained axial deformation
Wolf, Jonatan ; Profant, Tomáš (referee) ; Burša, Jiří (advisor)
Bachelor’s thesis deals with the significance of tension stresses produced by the bending of a beam with avoided longitudinal deformation. This problem is mainly solved by exact calculations of tensile stresses for different kinds of geometry, materials and the size lateral loads of the beam. The solution is done numerically using the MATLAB program. The result of this work is the assessment of tensile stress significance and comparison with other stresses, namely temperature stress. One of the partial results of the work is also the determination of the limit value of the slenderness of the beam for the given bending stress for which this tensile stress becomes significant.
