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.

Concrete structure of railway platform
Šimon, Jan ; Šulák,, Pavel (referee) ; Bažant, Zdeněk (advisor)
The bachelor´s work is has engeaged of the concept of a roof load-bearing construction of the railway covered platform. It is concernerd of a momolithic ferroconcrete scelet construction with a console panel. The weighting is put over to separate footing. The summary of the bachelor’s work is based upon dimenzation and designing elements of load-bearing construction accordance with ultimate limit state. Result of the each static calculation is design of armature .

Cross_section and reinforcement optimization of roof truss
Odvárka, Miroslav ; Šimůnek, Petr (referee) ; Laníková, Ivana (advisor)
The thesis is focused on optimization of cross-section shape of reinforced concrete truss. An optimization algorithm was created in Microsoft Office Excel which optimizes the shape and reinforcement of the reinforced concrete truss. The truss is as cheap as possible while complying with the ultimate limit state and serviceability limit state - deflection. The algorithm uses the Solver tool which is a supplement program Microsoft Office Excel. Two truss variants were created. One has a cross-sectional shape of a truss designed according to empirical relationships and the second comprises an optimized cross-sectional shape using the algorithm formed. The internal truss forces were detected using Scia Engineer. Both options were statically assessed. When comparing the variants, that a considerable part of the material cost can be saved when optimizing the cross-sectional shape.

Prefabricated reinforced concrete structures industrial hall with administration
Sitta, Martin ; Šulák, Pavel (referee) ; Zlámal, Martin (advisor)
As the main topic this thesis describes the design and evaluation of selected reinforced concrete members of the prefabricated reinforced concrete industrial building with administration at ultimate limit state in accordance with applicable standards. Movable overhead crane with carrying capacity of 50 tons is the main distinction of the industrial hall. Lateral frame whit main structural parts which are roof prestressed girder, load-bearing column supporting the overhead crane and drilled pile transferring loads from the upper construction to the load bearing subsoil, is designed in particular. Furthermore, design of the Gerber beam which forms the slab construction in the administrational part of the building is elaborated. Structural design and evaluation of other structures of the building is not part of this thesis.

RC load-bearing structure design of car park
Kudrna, Jan ; Perla, Jan (referee) ; Šimůnek, Petr (advisor)
The diploma thesis deals with the design and assessment of reinforced concrete structure supporting two-storey building of the underground garage for cars. In the space above the garage is designed open area with public space. The project was designed especially outer water-impermeable construction method white bath and a base plate and a perimeter wall. The structure was designed as a comprehensive model. Computing analyzed by finite element method. All selected elements were assessed at the ultimate limit state and limit state, namely to limit state of cracking load and forced stress.

Prefabricated concrete structure
Šimon, Jan ; Šulák, Pavel (referee) ; Bažant, Zdeněk (advisor)
The master thesis is about a design of supporting structure of prefabricated skeleton hall. The major part of a design are an internal trasverse and longitudinal frames, which contents roof reinforce concrete truss, columns, beam and ceiling joists. All the load acting to the bearing structure is transferred to the prefabricate footing made of reinforce concrete. Other parts of the bulding are not solved in this thesis. The content of the thesis consists of an assembly drawing of parts of the skeleton and the static calculation according to the actual international standards. The output of each static calculation is drawing of a shape of part and its reinforcement.

Design of Building on the Wenceslas Square
Moc, Ondřej ; Hladík, Pavel (referee) ; Zich, Miloš (advisor)
The Diploma’s thesis deals with the design of selected parts of reinforced and prestressed concrete structure. Internal forces were solved by software SCIA ENGINEER. Prestress concrete element was solved by module TDA. Phases of construction were considered. Detailed solution is focused on the design of reinforced concrete floor slab with joists within the basement, reinforced concrete beam with five spans within the basement, reinforced girder within the basement, reinforced column within the basement, reinforced footing and prestressed concrete joist within the basement. Drawings of shape and drawings of reinforcement are included in this thesis. Other elements of construction were not solved in this thesis.
