Design of prestressed box gireder bridge
Hofírek, Radovan ; Jurík, Michal (referee) ; Zich, Miloš (advisor)
This thesis deals with bridging of a lowland valley and the creek Dolanský in the section Jánovce – Jablonov on the Slovak motorway D1. Four variants of the bridge have been developed. Subsequently prestressed single box gilder with large overhangs that are supported by precast struts was selected as the most suitable variant. The construction of the bridge will take place in a formwork suspended on overhead launching scaffolding. The static assessment according to the Europan standard has been drawn up for this variant. The load of the bridge is projected according to the ČSN EN 1991-2 - Traffic loads on bridges and the dimensoin of concrete structures according to the ČSN EN 1992-2 - Concrete bridges - Design and detailing rules. The calculation of load is done using computer software SCIA Engineer 10.1 and Midas Civil.

Slab bridge over a local brook
Ondrušek, Martin ; Strnad, Jiří (referee) ; Nečas, Radim (advisor)
The bachelor's thesis deals with a prestressed slab bridge with one field. It is a road bridge that bridges a local river. A static calculation, which was verified by the Scia Engineering 19.1 program, was created. Ultimate and serviseability limit states were assessed.

Strength analysis of cutting tools
Petrlíková, Helena ; Madaj, Martin (referee) ; Zouhar, Jan (advisor)
This work is focused on the stress-strain analysis of a cutting tool. At the beginning, the study of available literature and scientific articles relating the topic is carried out. The solution of stresses and strains in whole real system has been carried out based on the computational simulation using the finite element method (FEM). The work contains a detailed description of the creation of the computational model. Model of geometry of the system has been created in the SolidWorks program. Computational simulation including the solution was implemented in the ANSYS Workbench program as well as in the classical environment of ANSYS 12.0. This work includes the presentation of results and subsequent stress-strain analysis of the cutting tool. Last part of this work deals with the modal analysis and harmonic analysis of cutting tools made in classical environment of ANSYS program.

Load model
Lašo, Matej ; Ptáček, Michal (referee) ; Kopička, Marek (advisor)
This thesis deals with power quality and load modeling. The issues of power quality, principles of load model creation and various types of loads and their principles are described and explained in this thesis. Various software and its main adventages in power systems modeling are described and various load models and simulations in PSCAD program are created and described at last.

Modelling and Analysis of Civil Structures in ANSYS Workbench Environment
Krňávek, Ondřej ; Kršík, Jakub (referee) ; Nevařil, Aleš (advisor)
This thesis deals with the use of the ANSYS Workbench software environment for modelling and analysing of civil structures. The introductory part is focused on finite element method, which is used by the ANSYS environment. The main part is dedicated to practical use of ANSYS Workbench environment for linear static analysis of reinforced concrete parking house. The thesis deals primarily geometric model, load model according to valid standards and at the end are listed calculated values of deformation and stress of selected components.

Study of dynamic effect on a bridge structure with moving loads
Zavřelová, Michaela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The goal of the master thesis is a dynamic parametric study on the dynamic effects of high-speed train using the HSLM-A load model on a railway bridge. The calculation model is processed, in RFEM 5.29.01 with RF-MOVE module and prerelease versions RFEM 6 and RSTAB 9, as a 2D member in the XZ plane. Furthermore, static load cases and load models LM 71 and HSLM-A are created. The HSLM-A load model is processed for universal trains A1-A10, which each cross the railway bridge at a total of 15 speeds ranging from 120 km/h to 400 km/h. A detailed parametric study of the dependence of the maximum deformation and acceleration in the Z direction on the speeds of each train set is performed. Modal and time history analysis is used in the parametric study. Part of the work is to determine the resonance region.
