Overpass bridge across the highway
Černý, Pavel ; Šopík,, Leonard (referee) ; Nečas, Radim (advisor)
The topic of this thesis is detailed design of the supporting structure of a bridge. Three variants are designed. The structure is designed as a single beam bridge of 6 spans. The calculation of load efects make in software MidasCivil 2019 and Scia Engineer 18.1. The subject of the expertise of the structure is service limit state and ultimate limit state. For evaluation of cross sections is used MS Excel. Both design and relevant drawing documentation of the bridge deck and substructure. The design and assessment are according to the europien standards.

Design of the speed-way bridge structure
Nádvorník, Ondřej ; Rybák, Vít (referee) ; Klusáček, Ladislav (advisor)
This Master's thesis deals with the detailed design of the supporting structure of the bridge with two sections, with the rise in the direction of the intermediate support, and cross-cut single-beam construction. The supporting structure is designed from the prestressed concrete, prestressing losses are accurately quantified. It also deals with the assessment of pillar base threshold and pilot groups. The assessment was carried out according to the limit states.

Bridge over the I/44 road
Topinková, Petra ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
My master's thesis aims to design a bridge construction spanning road III/443 over road I/44. Three versions were created one of which has been developed further. It is a three span bridge with a total spread of 77.5 meters. Proposal and evaluation of bridge construction is done unassisted. Static analysis is done using Scia Engineer program. Construcion evaluation is done by valid EU norms ČSN EN 1992-1-1. Mechanical drawing, building procedure and visualisation is also included.

Industrial Building - Review of Selected Reinforced Concrete Parts
Weber, Jozef ; Zlámal, Martin (referee) ; Švaříčková, Ivana (advisor)
Bachelor’s thesis deals with reinforced concrete floor structure. It is a 3D frame, which is composed of bar elements oriented in the longitudinal and transverse direction. The work is done calculating mean longitudinal beam and also the middle of the cross beam. Furthermore, the calculated floor structure, which operates in both directions. For the calculation of inner strength used computer program SCIA ENGINEER 2013.0, which operates on the Finite Element Method - FEM. All elements have been designed for ultimate and serviceability limit state. Work contains textual part, inner strength, static calculations, drawings and used documents.

Comparison of fatigue fracture criteria for torsion
Roh, Marek ; Slámečka, Karel (referee) ; Horníková, Jana (advisor)
The main goal of this bachelor thesis is to determine which criteria better suits the life prediction of the test sample loaded in the pulsating torsion. In the first part of this thesis fatigue failure will be examined, then fluctuating stresses will be characterized along with shear stress. Characteristics of the materials used will be specified in the second part. Lastly, the most appropriate criteria will be determined.

Qualitative study of beam finite elements
Martinásková, Magdalena ; Němec,, Ivan (referee) ; Nevařil, Aleš (advisor)
The issues were selected that have been expected to induce complications in modelling or calculations. These were solved in commercial softare RFEM, Scia, Axis and ANSYS using the FEM. The problems include geometric nonlinearities or address buckling or torsion. The basic theory and the software solutions are presented. For each task there are stated the parameters of calculation for individual programs, in more complex cases the way of assembling the model and solution steps are also described. The results obtained are compared to theoretical analytically obtained solution.

Analysis of chosen methods for solution of torsion of non-circular bars
Mach, Ondřej ; Rozehnalová, Petra (referee) ; Novák, Kamil (advisor)
This Bachelor thesis deals with analysis of chosen methods for solution of torsion of non-circular bars. The thesis is divided into two sections – theoretical section and research section. There have been introduced all needed terms and formulas used in analysed methods in the first part. In the second part, solutions of analytical methods have been compared with solutions obtained by numerical method FEM (Finite Element Method) modeled in ANSYS software.
