Roof structure of construction for social purposes
Bašista, Ján ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The work treats the static recalculation of an existing roof structure of a construction for social purposes and proposes two variants of the design of a new roof structure. The construction has a rectangular ground plan of 30 m x 47 m and the roof structure is placed on the load bearing circumference concrete walls. Except for the load constituted by the function of the construction and by the climatic area, an extra load of 2 tons suspended at any place of the structure is considered because of the special requirement of working and technological equipment. The variant no. 1 is designed from the steel S355. The variant no. 2 is designed as a combination of the wood GL24h and the aluminium EN-AW 5083. Both of the variants have 11 transverse load bearing girders. The purlins are perpendicular to the girders and are placed on them. Stiffness is secured by roof stiffeners.

Planetarium
Sokolová, Eva ; Šmak, Milan (referee) ; Barnat, Jan (advisor)
The master’s thesis object is to create a design of a load carrying steel structure planetarium. Its ground plan dimensions are 36,1 x 49,0 m. The planetarium hall’s roof is designed with system of trusses and purlins. The projection hall’s roof consists of ribbed cupola with radially arched ribs. The stiffness of the whole construction is ensured with bracings. The walls of the whole object are composed of columns, rails and bracings.

Bridge over the Živný Brook
Sekanina, Josef ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
This thesis occupies with the design of the road bridge over the stream Živný, a railway lane and a projected road between Běleč village and Husinec village. There are designed three variants of bridges. The variant no. 1 – continuous box girded beam – was chosen for the detailed analysis. The pre-stressed concrete road bridge is designed and evaluated according to European standards – Euro codes. The sequential construction influence and its impact on the construction is also considered in the calculations. The drawing documentation and the visualization of the bridge are made.

Cowhouse in Králíky
Nováček, Tomáš ; Štrba, Michal (referee) ; Barnat, Jan (advisor)
Bachelor thesis describes the structural design of the load bearing steel structure of cowhouse located in the municipality Králíky. The structure is designed according to the normative requirements of ČSN EN for ultimate and serviceability limit state. It´s a structure formed by the main frames at a distance of 5 m apart, which are placed in a rectangular plan of 30 x 60 m. As the main material of load bearing elements was used a steel S355. The specificity of the structure is location in a place with above average snow and wind loads. The couwhouse is intended for housing hundred and fifty cows. The work consists of a static calculation, which assessed individual cross sections and joints.

Reconstruction of the Building for Storage
Heger, Petr ; Buchta, Stanislav (referee) ; Hron, Lukáš (advisor)
The subject of this bachelor’s thesis is to design the extension of the steel structure of the storage hall. The task is to double the platform area from 18 x 18 m up to 36x18 m with the height of 7,5 m. It is required to use as much of existing profiles as possible. The structure is located in Znojmo. The original roof structure is made of truss girders with the segmently curved lower girdle. The span of main frame is 18 m and the axial distance of main frames is 6 m. All girders are pinned. In extended structure is used the plate girder. Spatial rigidity of the structure is made by wall and roof bracing. The static calculation of main load-bearing elements including joints and specific details was made for the structure. The technical report and drawings were specified by the supervisor. For design of the structure were used valid standards ČSN EN.

Railway bridge across the river Svitava
Findura, David ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
This thesis deals with a design of an one-track railway bridge over the river Svitava. Out of three proposed variants was chosen as the most economical and feasible the variant number 2 - two-beam prestressed bridge with one span. According to actual EN standards the construction was designed and assessed to the serviceability limit state and the ultimate limit state.

Design of a one-span beam bridge
Podškubka, Patrik ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The aim of the work is to design a new safe and economical bridge construction, over the existing communication, category S7,5, according to currently valid standards and regulations. Out of the three proposed variants was chosen the variant of a prestressed one-span bridge with two beams and a length of 26,750m. The category of the transferred communication is S7,5.

Static analysis of flexibly supported on structures
Šnajdárková, Jana ; Brdečko, Luděk (referee) ; Vlk, Zbyněk (advisor)
This work focuses on comparing the static analysis on the various types of models. It is calculated as manual calculations and in software RFEM. Without use of the software are created simplified beam model on fixed and flexible supports and to them are calculated support reactions, shear forces and bending moments. One part focuses on the calculation of the reduction of bending moments, to achieve more accurate results. In the program are created models of rod and models of space, which are composed of surfaces. There is also created a model of the split rod to form a reduction of the bending moments over the supports. The last model is a beam with two separate chambers, which are fixed to the plate and defined as ribs which cooperates with the plate. Internal forces on all models is then compared.

Spatial reinforced concrete frame of the industry object
Body, Roman ; Šulák, Pavel (referee) ; Šimůnek, Petr (advisor)
The aim of bachelor thesis is design and appraise the structure of the spatial reinforced concrete frame of the industry object founded on foundation slab. The structure is without the cladding. To the calculation of internal forces is used computing software Scia Engineer 2013.1. Roof slab, rung, beam and column are designed. Designed life of the structure is 50 years.

Space structure of industry building object
Pelikán, Adam ; Švaříčková,, Ivana (referee) ; Šimůnek, Petr (advisor)
The subject of this project is the structure of the storage hall which is made of reinforced concrete. It is designed as precast frame (span of 18m), founded on pocket footings. The roof deck (non-rigid) consists of ribbed slabs. The cladding is made of sandwich panels (reinforced concrete and isolation) layed on foundation beam. The design is focused on the single typical frame. Roof girder, column and pocket footing are designed. Designed life of the structure is 50 years.
