The influence of the outdoor temperature on the properties of the reinforced layer in the implementation of ETICS
Novotný, Michal ; Gašparik,, Jozef (referee) ; Schmid, Pavel (referee) ; Sedlák,, Petr (referee) ; Lízal, Petr (advisor)
The trend in today's civil engineering are growing demands for quality and comfort constructed buildings and spaces in them. This trend causes a change in the approach to designing buildings and building new buildings. One of the main directions great importance is attached dedicated reconstruction of buildings and their technical adjustments to meet the ever increasing demands being norms and laws. One of the most monitored parameters are thermal-technical characteristics of objects - i.e. better quality means saving on heating costs. In this connection there is a big trend of the modern construction industry and building insulation, mainly ETICS systems. Dissertation focuses on the basic (reinforced) layer of the ETICS and examines the effect of low temperatures, acting on the matter in the implementation of the system, the properties of this layer. This coating is one of the key elements of the system, which more or less determines the quality and durability of the system. The first part deals with the current state of the problem and generally insulation systems, basic types and the advantages and disadvantages of these systems. In the main part of the work is solution focused work, its objectives and methodology for testing materials using laboratory tests and are mentioned outputs of experiments in terms of results. The final section addresses the evaluation of the data and results and output for construction practice. The theme of work was also addressed in the specific research. The works are also numerical and graphical attachments to records of experiments and calculations.

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.

Simulation of Effects of Short-circuit Currents in HV Switching Stations
Tománek, Miloslav ; Buriánek, Jiří (referee) ; Toman, Petr (advisor)
This thesis is engaged in a theoretical calculation of short-circuit currents in electric power system in compliance with the norm ČSN 60909-0 and first of all with calculation of dynamical and thermal effects of short-circuit currents in HV switching stations in accordance with the norm ČSN 60865-1. Next the thesis is engaged in a production of programs for simulation of mechanical effects of short-circuit currents with respect to a dimensioning of constructional elements of switching station and afterwards in a practical simulation of selected parts of the real switching station type „H“ in Slavkov u Brna.

Proposal of a program for solving of problems of simple tension/compression of bars and strut frames
Martínek, Tomáš ; Kubík, Petr (referee) ; Polzer, Stanislav (advisor)
The aim of this work is a program that will solve problems from the simple tension /compression bars and strut frames in the range of bachelor. The work consists of two programs developed in the Borland Delphi development environment. The programs allow the user to define a bar (strut frames) on the basis of the geometrical parameters and constraints, determine the rate of statical indetermination, make the necessary calculations and, if necessary, indicate the condition of deformation (a program for solving bars). The written part of the work serves as a manual.

Piston group of in-line four-cylinder gasoline engine
Král, Stanislav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of the thesis, it is strength control group of ordinary four-cylinder piston gasoline engine. In the first part of the specified thermodynamic, geometric and operational parameters of the motor piston group will calculate the thermodynamic cycle. Furthermore, we see the effects of force acting on the piston group in the most strained moments of the cycle. For the reconstructed load piston group perform voltage control in piston pin and strength control rods of the eye. In conclusion, we compare the calculated values of permissible stress values and find a design safety factor for the part.

Comparison of selected parameters of tensile strength of concrete
Rozsypalová, Iva ; Žítt, Petr (referee) ; Daněk, Petr (advisor)
The thesis deals with a comparison of the selected strength tension properties of the hardened concrete and finding relationships between them. This is essentially a simple tensile strength, tensile flexural strength and tensile splitting strength. The text describe the testing procedures to determine the tensile strength of concrete. Furthermore, there are presented the results of testing on different types of concrete (plain concrete, lightweight concrete, steel-fiber concrete, polymer-fibre concrete and high strength concrete). The conclusion deals with the derivation of dependancy between concrete strengths and comparing the values obtained from the available relations with the results of the tests.
