The reconstruction of the prestressed railway bridge
Macková, Lucie ; Šedivý, Jan (referee) ; Klusáček, Ladislav (advisor)
Diploma thesis describes the design of main structure reinforcement of the railway bridge ,,Gagarin’’ in the 5,872 km of route Český Těšín – Ostrava Kunčice. Reinforcement is achieved by combination of composite slab-shaped channel with the continuous gravel ballast and free additional prestressing cables. There are 3 variants for which the design and assessment of main structure is performed. Evaluation of the options is performed on basis of calculations. There are made additional calculations and drawings for best variant.

Steel structure of a business centre
Kočí, Petr ; Pilgr, Milan (referee) ; Štrba, Michal (advisor)
The diploma thesis elaborates on the proposal of a loadbearing steel structure of a shopping centre. Four-storey building has total lenght of 88 m, width 48 m and its base structural grid is 8 x 8 m. The total height of building is 25,4 m. First three floors above ground are designed with structural height of 5,6 m whilst the 4TH floor uses height of 4,0 m. Frame structure is formed by primary beams and castellated secondary beams. Above 4TH floor, the roof structure is designed in two alternative versions, both using solid purlins and truss girder. The 3D computer animation of the building is also part of thesis. The shopping centre that is subject of the final thesis is located in Brno area.

Shear bearing capacity of composite slabs
Holomek, Josef ; prof. Ing. Alois Materna, CSc., MBA (referee) ; Keršner, Zbyněk (referee) ; Bajer, Miroslav (advisor)
The subject of the submitted work is the experimental and theoretical investigation of composite slabs. The work also deals with creation of numerical models of composite slabs. The design of a new type of steel sheeting for composite slab according to nowadays standards requires full scale laboratory bending tests. An alternative to the bending tests are the small scale shear tests. The small scale shear tests as well as corresponding design methods have already been investigated by many researchers. Therefore several test arrangements and corresponding design methods can be found in literature but none of them is included in standards yet. The submitted thesis describes three of the alternative design methods: Slip- Block Test, Simplified Method and Built-up Bars. The test arrangement is proposed to be usable in all these methods. The small scale shear test have been performed in laboratory in several modifications. The results were used to calculate the bending resistance of the slab by the alternative design methods. The calculated bending resistances were mutually compared, compared with the performed bending tests resistances and the resistances by the methods described in Eurocode: m-k method and partial connection method. A sensitivity studies of the input parameters in alternative design methods are presented as well. The optimal design method for use in practice was searched and recommended based on the performed studies, accuracy and laboriousness of the methods. The shear tests were used also to measure longitudinal shear resistance of the additional shear anchors. The alternative design methods were used to predict bending resistance of the slab using these anchors and the results were compared. The numerical simulation of the composite action of the slab by the finite element methods is modelled in Atena software. The models serves to perform parametrical studies and to better understand of the behaviour of the slab in partial composite action.

Administrative Centre
Rádlová, Markéta ; Sýkora, Karel (referee) ; Bajer, Miroslav (advisor)
This diploma thesis deals with the design and assessment of the steel structure of the administrative building. The building is situated in Svitavy. The construction has several floors, the ground plan is L-shaped. Other floors have a rectangular ground plan. The external ground plan dimensions of the building are 55.2 m × 72 m. The building has terraces and three height levels occupied. At the first height level the building reaches 5 floors, the other 7 floors and the top 9 floors. the main material will be S235 steel on the construction.

The office building structure in Brno
Svršek, Josef ; Štrba, Michal (referee) ; Šmak, Milan (advisor)
The topic of this bachelor´s thesis is a design of construction of an office building. The building´s floor plan has a rectangle shape with a dimension 32x21 metres. The roofing above the third floor is made of timber structure where the main load-bearing element is a glue laminated timber beam. The terrace, which is placed in the third floor, is designed as a green roof. The load-bearing structure of the building is designed of steel and the ceiling consists of steel concrete slab. The statics solution was implemented using the Scia Engineer 17.1 software.

Storage hall with administrative part
Žáček, Libor ; Barnat, Jan (referee) ; Štrba, Michal (advisor)
The subject of the bachelor's thesis is the design and assessment of the steel load-bearing structure of a storage hall with an administrative part. The proposed building is located in Uherské Hradiště. The floor plan of the building is 24 x 40 m and the height is 9.0 m. The main load-bearing structure is designed as a two-hinged frame made of rolled IPE profiles. The girders and axillars are designed from thin-walled profiles. The ceiling structure in the administrative part is designed as a composite concrete slab in trapezoidal sheet.

Bridge over the Senice river
Urbánek, Filip ; Velešík, Marek (referee) ; Panáček, Josef (advisor)
This bachelor's thesis deals with the design of a road bridge over the Senice river. In the beginning of the thesis there are designed three variations of the bridge. The variation with prestressed prefabricated girders with composite slab is chosen for more detailed assessment. Time-dependent analysis is taken into account in the structural design. Detailed structural design is made and selected parts of the construction are checked for ultimate and serviceability limit state by Eurocode. Detailed drawings and visualization are made as well.

Business Centre
Dežerická, Lucia ; Pešek, Ondřej (referee) ; Pilgr, Milan (advisor)
This diploma thesis deals with the design and assessment of the two different variants of the steel structure of the business centre. The building is situated in Uherské Hradiště. The construction has several floors and the ground floor in the 1st floor is 32 x 32 m, it gradually extends evenly up in 2nd floor and 5th floor, to the total ground plan dimensions of 48 x 48 m. The building has 8 floors and its maximum construction height is 40 m. The supporting system of the structure is designed from S 355 steel, it consists of steel-concrete beams, dies and columns.

Shopping mall in Brno
Brozmanová, Dagmar ; Horáček, Martin (referee) ; Pešek, Ondřej (advisor)
The aim of the diploma thesis is to design and assessment of the steel structure of shopping mall, which is situated in Brno. Three variants were processed, from which one was selected for more detailed processing. Variants have hexagonal floor plan with maximum dimension 60,0 m, four floors and same structural solution. They differ in plan of secondary beams and columns, in floor plan of glass atrium and used cross-sections. Building´s load-bearing structure consists of pin-supported columns, primary beams, secondary beams and purlins. Rigidity of the structure is enshured by system of vertical bracings and in horizontal direction by composite slab. The structure elements are made of steel S355, except secondary beams, which are made of steel S235.
