Prestressed road bridge
Pokorná, Šárka ; Jaromír,, Rušar (referee) ; Panáček, Josef (advisor)
The subject of this thesis is the design and assessment of a prestressed bridge structure. Two studies of the bridging were created. The selected variant is a continuous post-tensioned single-frame structure with three spans. The total theoretical span of the bridge is 100,0 m. The bridge is to be constructed in its entirety using a falsework. The structure has been assessed for serviceability limit state and ultimate limit state according to the relevant standards.

Variant solution of concrete flat slab supported by columns
Fárková, Karolína ; Pulec, Vladimír (referee) ; Perla, Jan (advisor)
The thesis focuses on the design and assessment of a locally supported ceiling slab. The slab was designed in two variants: a reinforced concrete slab and a prestressed slab, both of which were subsequently approximately economically evaluated. To calculate internal forces, a 3D model was created using the FREM 5 program. The structural analysis was conducted using the finite element method and the method of equivalent frames. Both slabs were assessed for ultimate limit state and serviceability limit state.

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.

Design of a one-span bridge over a local brook
Haluška, Ľuboš ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analsysis of a one-span bridge over a local brook. Two variants were designed. The variant of one-span prestressed beam bridge with lower bridge desk was chosen for analysis. The calculation of load effect was made in software Scia Engineer. The supporting structure is assessed for the ultimate limit state and the serviceability limit state according to the europien standards. The time dependent analysis is not trated in this thesis.

Prestressed bridge over the Budišovka river
Hroudná, Denisa ; Zich, Miloš (referee) ; Koláček, Jan (advisor)
The subject of this bachelor's thesis is the design of a prestressed bridge over the river Budišovka. Three preliminary studies have been proposed and one of them was selected for more detailed processing. Span length of construction is 18,0 m. Selected variant was assessed for ultimate and serviceability limit state according to CSN EN 1992-2.

Road bridge in Budišov nad Budišovkou
Šedová, Linda ; Strnad, Jiří (referee) ; Koláček, Jan (advisor)
The subject of this bachelor’s thesis is to design a one field road bridge in Budišov nad Budišovkou. The supporting structure is from prestressed concrete with the lenge 21,0 m and span lenght of construction is 18,0 m. The load effects is calculated by Scia and compare with manual calculation. Selected construction was assesed for the serviceability limit state and the ultimate limit state according to ČSN EN 1992-2.

Load bearing RC structure of office building
Ferencz, Balázs ; Zlámal, Martin (referee) ; Šimůnek, Petr (advisor)
The Master’s thesis is focused on the analysis and design of selected members of load-bearing structure of an administration building according to the ultimate limit states (ULS) and seviceability limit states (SLS). The calculation and the analysis was supported by design software SCIA ENGINEER 2012. Structural analysis deals with the design of the reinforced concrete (RC) flat slab above the 4rd strorey which is particularly supported by RC columns and particularly lies on RC walls. Furthermore, the Master’s thesis contains analysis of some selected columns of last three storeys, column of lowest storey, construction of stairway between 4rd and 5th storeys. The work beside this deals with the calculation and design of foundation of the object. The rest parts of the load-bearing structure are not solved in the Master’s thesis.

Road bridge over the Budišovka river
Zývala, Pavel ; Požár, Michal (referee) ; Koláček, Jan (advisor)
The aim of this bachelor thesis is to design of bridge construction over the river of Budišovka located near the village of Budišov nad Budišovkou. The load bearing system is composed from one reinforced concretespan. The structural design was made in two variants, which were compared between them. For calculations of first way was used the software of Scia Engineering 16.1 and second way was calculated by simplified manual method of effective width. All calculations were performed according to actual standard EN.
