Sheeting of Foundation Pit
Vodáček, Ondřej ; Chalmovský, Juraj (referee) ; Glisníková, Věra (advisor)
First part of the thesis talks about pit sheeting in general, including shafts and trenches as well as pits, however pits are the very main topic and therefore described in details. This part also discusses earth pressure and groundwater issues as applied loads, yet only marginally. Second part demonstrates a particular sheeting structure and its calculation. All presumptions are established here, including double-anchored sheet pile wall geometry, spoken earth pressure loads and groundwater loads plus heavy equipment load during a construction. The calculating process is shown using computer softwares (Plaxis 2D, GEO5) and also in a non-software way using just pen and paper. At the very end of thesis an ultimate limit state (ULS) of sheet piles is assessed, software and non-software results are compared to each other and discussed.

Design of underground garage in Brno
Hájek, Jan ; Hladík, Pavel (referee) ; Zich, Miloš (advisor)
The goal of the project is behaviour and dimensioning of selected monolithic concrete structure elements. Design and assessment of the building foundation was made. Slabs of the floors are dimensioned in detail. All computations are made in accordance with Eurocode 2. Drawing documentation is part of this project.

The design of multi-storey building
Hardubej, Martin ; Girgle, František (referee) ; Švaříčková, Ivana (advisor)
The aim of the thesis is the design and assessment of selected elements of a new build multi-storey office building. The supporting structure of monolithic reinforced concrete skeleton is modeled SCIA Engineer and burdened set load cases and combinations. The outputs of the internal forces of the calculation program are dimensioned selected elements. Selected elements include locally supported slab, columns, column shoes, basement wall and footing still. The thesis is selected reinforced concrete elements assessed on the ultimate limit state. The output of this work is static calculation of individual elements. Another part of the output consists of drawings solved elements.

Design of residential house
Moravcová, Eva ; Loudil, Lukáš (referee) ; Zich, Miloš (advisor)
This is a residential house in Brno. The supporting structure is reinforced concrete. The building has one basement and six floors. Vertical load-bearing structures are made up of reinforced concrete columns and walls. Horizontal load-bearing structures are formed by slabs (bearing in both directions). The staircase is concrete slab. Foundation is on piles. Infill vertical structures are brick. In the fifth floor pool is located.

BUT Technology Transfer Center
Muroň, Jakub ; Štikar, Jaroslav (referee) ; Nový, Alois (advisor) ; Skála, Jiří (advisor)
The Bachelor’s Thesis is based on the architectural study done in the summer semester of the third year of bachelor’s studies of the topic Technology tranfer cetre BUT in Brno. Area of Technology transfer centre of BUT (Brno university of technology) is composed of three separated units - two production complexes and main buidling, which is used for administration in first floor and laboratories in second floor. Design is conditioned by two criteria - an adaptation of objects structure to configuration of terrain and a flexibility of function and logistic. Solution to these issues was to create main communication connected with existing communication. It provides easy and fast logistic service for the production complexes. Shape of the buildings follows contour lines. Due to dynamic shapes I designed simple industrial monochromatic facade, which allows an experimentation with the mass of the building. Line of the flat roof was broken by simple skylights. Strip windows potentiate horizontality in contrast with the main building, which has vertically based character. Industrial character of the complex was accentuated by using metallic facade and prefabricated concrete construction.

Foundation design of River Garden III in Prague
Malinský, Martin ; Boštík, Jiří (referee) ; Svoboda, Petr (advisor)
The topic of this master's thesis are the design of ensuring foundation pit and foundation of administrative building in Prague. In the vicinity of foundation pit is situated the river Vltava, which directly influences the ground water level at the job site. During construction, it is necessary to envisage the possibility of occurrence of the old building structures of docks.

Modelling of diaphragm walls using time-dependent elasto-plastic material model
Šindelářová, Daniela ; Kotačková, Alena (referee) ; Chalmovský, Juraj (advisor)
The goal of this thesis was the verification of the advanced time-dependent elasto-plastic material model for modeling diaphragm walls. Currently, this type of construction is solved usually with a combination of linear-elastic volume and plate elements. To express time-dependent behaviour, there are both, volume and plate, elements active in short-term conditions, then only volume elements in long-term conditions, while plate elements are deactivated. In this thesis, the Shotcrete material model, which can capture the time-dependent behaviour without combining two types of construction elements, is used. First, a theory of time-dependent behaviour is presented and a design of concrete structures by Eurocode 2 is discussed. Next, the Shotcrete material model is described, then used for modeling a biaxial test and calibration of compression and bending test. Following the gained knowledge, a real boundary value problem of deep excavation supported by diaphragm walls with the strut was solved. To calculate values of the internal forces and horizontal deformation in diaphragm walls, three types of material models are used.

Návrh podzemní stěny ovlivněné výkopem z obou stran
Kočičková, Veronika ; Polák, Barnabás (referee) ; Uhrin, Michal (advisor)
The aim of this thesis was simplified design of diaphragm wall affected by excavation from both sides. This wall is a part of temporary shaft that serves for exchange of tunnel boring machines and at the same time it is a permanent structure of an adjacent metro station. Part of the thesis deals with description of construction sequence of diaphragm walls, excavation of the shaft, excavation of the adjacent metro station and following construction of metro tubes and backfilling of the shaft. Inseparable part of the thesis is assessment of geological conditions and geotechnical parameters. Furthermore, a study on temperature loads on struts was carried out and the results of the study were used for design of the struts. To fulfil the requirements of the assignment several models of the shaft structure and adjacent metro station were built in program Plaxis and one model of the diaphragm wall of the shaft was created in program Geo5. The model outputs were subsequently compared to each other. Furthermore a model of lateral support frame was created in program Scia Engineer. Outputs from programs Plaxis and Scia Engineer were used as a basis for design checks of the structure. The design checks were done according to Eurocodes. The diaphragm wall and the lateral support frame were designed to support the loads considered in this thesis. In order to simplify the calculation variable loads from construction machines were not considered and the only variable load considered was the temperature load on struts. Lateral support frame was also designed to accidental load – loss of a strut.
