Realization of the top rough construction of a residential building Valtice
Sedláček, Stanislav ; Čech, David (referee) ; Novotný, Michal (advisor)
The subject of this thesis is to address the technological upper stage of construction site of a residential building in Valtice particular proposal technological process for the realization of supporting structures. This involves the vertical and horizontal construction made the building system Velox, which uses štěpkocementové boards for the creation of permanent formwork. In the technological regulations are handled during construction practices and policies for compliance with safety at the construction site. The work also includes a proposal building equipment, machinery, develop a timetable, inspection and test plan and building system Velox compared with the system Porotherm in economic terms, time and heating technology.

Analysis of the influence of pressing force on the weld joint strength of the composite component
Litera, Jan ; Sedláček, Stanislav (referee) ; Vosynek, Petr (advisor)
Nowadays, components made of metallic materials are increasingly being replaced by components made of plastics or composites with a polymer matrix. This is associated with the issue of production processes such as pressing or welding, i.e. the influence of process parameters on the output properties of the product. The presented thesis deals with the issue of the combination of pressing and welding of a composite part, specifically the influence of the pressing overlap on the strength and tightness of the welded joint. The first part is focused on a search of available literature related to the problem. The second part deals with solving the problem using experimental modeling. Part of this chapter is inclusion of computational modeling in the design of experiment, detailed measurement of essential dimensions, microtome analysis and statistical processing and evaluation. The third part focuses on the creation of a method for evaluating the strength of the weld based on the pressing overlap using computational modeling. Essential part is also validation of the computational model based on previous experimental measurements. Finally, two methods for evaluation of the weld strength are presented. The first works on the basis of computational modeling and the second on the basis of experimental modeling. At the same time, the presumptions of usage of the created methods and their drawbacks are pointed out. Furthermore, the possibilities of their implementation in the initial design of the welded joint and the proposal for the next procedure are described.

Commercial building in Brno - the construction technological planning
Sedláček, Stanislav ; Štěpán, Richard (referee) ; Motyčka, Vít (advisor)
The aim of my thesis was to perform construction and technological preparation of the construction of commercial house in Brno in the street Křídlovická. The introduction contains the expected design and construction process of the proposed building as a whole. It is also prepared a preliminary draft of the financial cost of the entire project designed according THU and object schedule. Furthermore, the implementation of the project construction site for a major part of the commercial house. Gradually work focuses mainly on the implementation of the technological stage of construction site with detailed processing procedure for the implementation of monolithic concrete structures of the building.

An aplication of the boundary element method to the problem of the crack in the vicinity of the bi-material interface
Sedláček, Stanislav ; Vrbka, Jan (referee) ; Profant, Tomáš (advisor)
There are many shape and other changes in the engineering constructions. These changes cause the concentration of the stress. There is a higher probability of the crack initiation in the vicinity of these stress concentrators. The problems of the crack can be solved nowadays only with help of sufficient numeric tools. The Boundary Element Method is one of the many numerical tools which offer the solution of some problems of the mechanics. The goal of this diploma thesis is to formulate boundary element method for the plane problem of the linear elasticity for izotropic material with different types of the stress concentrators.
