Prestressed bridge over the river
Kačer, Karel ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
As the thesis I chose static solving bridging the road. This is a real first-class roads situated near the city Kolín in the Central Region. The bridge will be used to transfer traffic across of local Sendražický stream. At the beginning I determined three main variants of supporting design and then I chose one for more detailed processing. It is a armored concrete slab solidified two prestressed ribs arching spanning 18.3 m The calculation is implemented by software Scia Engeneer in accordance to European standards.

The assessment of existing industry hall structure
Hamrlík, Martin ; Chalabala, Jiří (referee) ; Klusáček, Ladislav (advisor)
The bachelor's thesis is focused on an assessment of existing industry hall structure of a rectangular floor plan. The supporting system design consists of a precast reinforced concrete skeleton. The aim of this work is to determine the structure of the expected loading of a new crane runway. The subjects of assesment are columns, girder of crane runway, short corbel and concrete foot. In other part of the project is designed reinforcement nonconforming elements. The work includes the development od structural analysis, drawing of hall structure and reinforcement drawings of reconstructed elements.

Cable-supported pedestrian bridge
Tichavská, Andrea ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The scope of the thesis is the design of a cable-supported pedestrian bridge. The structure of the pedestrian bridge is formed by concrete bridge deck supported by external cables. The transmission of the prestress is provided by steel elements. The main goal of this project is the design of prestressed concrete bearing structure. Construction phases will not be taken into consideration.

Fibre reinforcement with plasma in cement composites
Žižková, Lucie ; Hela,, Rudofl (referee) ; Bodnárová, Lenka (advisor)
The usage of polymer fibres can be increased by the new progressive method of the plasma treatment. This thesis is focused on verification of the influence of the low-temperature treatment on polymer fibres´ surface used in concrete. The treatment of polypropylene fibres in low-temperature plasma is described in the theoretical part. The impact of the treatment on the volume differences of cement composites is also evaluated. The influence of the addition of commercially available fibres and plasma treated fibres on the volume differences of cement composites is also experimentally verified.

Semi-detached house, Lanskroun
Němec, Ondřej ; Kalábová, Tereza (referee) ; Bečkovský, David (advisor)
The bachelor thesis is based on design of semi-atteched house on the street Slovenské in Lanškroun. Bulding plot is situated in new city quarter determined for family houses outside the city center. Shape of semi-atteched house is almost rectangle and it is made of two parts where each part is designed for family of four to five members. All living rooms are oriented to south that allows residents to enter the garden and the patio in first floor. Each part of house includes garage for one car.

Resistance of the roof structure loaded with photovoltaic panels
Holoubek, Jan ; Bažant,, Zdeněk (referee) ; Strnad, Jiří (advisor)
The aim of the thesis is to verify the resistance of the roof structure loaded with photovoltaic panels. On the roof of industrial building of rectangular plan with dimensions of 26,5 x 24,5 m in Hlinsko, the investor decided to install photovoltaic panels. Preliminary diagnostic survey showed only flexural reinforcement in the field of all considered load-bearing elements. Bending strength was assessed by these structural elements: reinforced concrete slab, reinforced concrete beam, reinforced concrete grinder. Static calculation includes a minimum reinforcement of support and necessary shear reinforcement, which must be demonstrated by a detailed diagnostic survey. The structural analysis includes the assessment of reinforced concrete beam deflection after loading. All assessments were performed according to currently valid Eurocodes. The calculation showed that all supporting elements meet the bending resistance and deflection of the beam is smaller than the limit value laid down in the EC, so the roof of the hall can be loaded with photovoltaic panels.

Reinforced Concrete Frame - Design of Selected Part of the Building
Hardubej, Martin ; Zlámal,, Martin (referee) ; Švaříčková, Ivana (advisor)
The thesis is focused on an assessment of existing structures at the four-storey apartment building. The supporting system design consists of a monolithic reinforced concrete skeleton. The subjects of assessment are girders, columns, beams and continuous slab. Another part of the project focuses on the design for reconstruction of nonconforming elements, which are the girders and beams. The work includes the development of structural analysis and reinforcement drawings of reconstructed elements.
