Steel lookout tower
Kábrt, Michal ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of the diploma thesis was to make a structural design of steel-load-carrying structure of steel lookout tower, in the grounds of domestic brewery in Humpolec. Lookout tower will be part of newly built centre for customers of the brewery. The layout and shape of the load-carrying structure of steel lookout tower follow the brewery chimney with height of 32.7 m with circular ground plan and outside diameter of 3.5 m in the heel and 2.3 m at the top. The chimney is independent of the construction of the lookout tower. The ground plan and dimensions of the lookout tower were considered taking into account the required spacing of the structure from adjacent buildings and ensuring sufficient dimensions for the required passage between the future lookout tower and the existing building of the boiler room. RFEM was used for calculation internal forces and assessment on individual structural elements, according to the valid Eurocodes.

Administrative building of South Moravian Gasworks
Žwaková, Vendula ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this Master’s thesis was recalculation and design two variants of existing supporting steel structure storey administrative building which is located in the complex of Jihomoravská plynárenská a.s. in the city center of Brno. Dimensions and disposition based on the specifications of the Master‘s thesis. The total height of the structure is 29.46 m and circular platform has a diameter of 16.088 m. The supporting structure of an existing building consists of circumferential lattice structure. The main supporting elements of both variants are columns. Option A has 8 columns. Option B has 16 columns. These two variants were preliminarily designed and statically evaluated. After that was made a comparison of variants, and one was selected for more detailed processing (Option A). This included the calculation of anchorage, draft of mounting joints, technical report and drawing documentation.

Railway bridge with steel load-carrying structure
Šarmanová, Iveta ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of master’s thesis is a structural analysis of a bearing structure of an existing historical single-track railway bridge over the Vltava river in a direction from Prague Modřany to Vrané nad Vltavou. The riveted steel bridge carries rail traffic across five fields. A part of the master’s thesis is focused on a disposal of a variant of the longest field by using a modern arch construction.

Load carrying steel structure of the sport stadium roofing
Hubáček, Ondřej ; Karmazínová, Marcela (referee) ; Melcher, Jindřich (advisor)
This diploma thesis deals with design load bearing steel structure of the sport stadium roofing with 67,2 m length and 28,8 m width. Roofing structure is designed and examined in two versions. Variant A is designed like tubular truss girder with axis distance 4,8 m. Variant B is designed like welded solid-web girder with same axis distance. These versions are compared by weight, manufacturing complexity and appearance, preferable version is processed in detail. Drawings contain layout of both versions and manufacturing drawings of truss.

Family house load-bearing structure composed of thin-walled steel members
Bulíček, Radek ; Melcher,, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of the bachelor thesis is to design and verify load bearing members of single-storey family house composed of thin-walled cold-formed elements. Parking space for cars of timber members is the part of the house, too. The family house is in rectangular plan with dimensions of 9.5 x 10.5 m. The roof of the house is hipped, on the side of the house with the parking place rafters are associated with garage rafters. The following elements were statically assessed: structural members of the house roof (rafters, collar tie, roof bracing), structural members of the ceiling (ceiling beams), reinforcing timber frame, external and internal load bearing walls (columns), load bearing elements of the parking space (rafters, purlins, columns). All assessments were performed according to currently valid standards. The calculation showed that the resistance and serviceability of all components are satisfied.

Static verification and variant design of steel structure of railway bridge
Boček, Michal ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this diploma thesis is static verification steel structure of exist railway bridge in accordance with the valid standards. The bridge have three simple spans with a span of 25; 98 and 25 meters, outer fields are simple beams, the middle field is the beam reinforced with an arch with vertical rods. Steel orthotropic deck with longitudinal stiffeners and crossbeams. Further were designed and analyse other possible options super structure of the middle field, and the resulting variant as a circle span with radial rods was detail solved and made documentation.

Possibility of using of fibre-concrete at composite steel-concrete structures
Pozdíšek, Jan ; Karmazínová, Marcela (advisor)
The aim of the offered thesis is an analysis of usage of uncommon concrete matrix and its contribution to steel-concrete composites structures. It especially refers to the area of internal supports, where usually acts negative bending moments. These statical systems are very often used for bridge structures, or even for building constructions. Nowdays, the static infuence of concrete at the area of negative moment is neglected. Only the steel part of cross section and steel reinforcement are included to the static action. This work is focused on the usage of tensile strength of uncommon concrete. The improvement of tensile strength of cement matrix is due to glass fiber reinforcement acting as scattered reinforcing. The introduction is focused on common approach of design of the structures mentioned above. Next, there is a part which describes possibilites of using fibre reinforcing until nowdays.

Steel structure of training tennis hall
Vlček, Radek ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The content of the bachelor thesis is a proposal and evaluation of a steel load-bearing structure of a rectangular tennis hall with a floor space of 40x63 m. The building is situated outside the urban area near the Moravičany municipality. The hall consists of 11 cross-links spaced by 6.3 m. The main load-bearing system consists of spatial arched trusses, purlins and lateral bracing that support the spatial rigidity of the construction. The calculations were made in compliance with the Czech technical norms ČSN EN.

Roofing of railway station "Brno - Main Station"
Jež, Matěj ; Pešek, Ondřej (referee) ; Karmazínová, Marcela (advisor)
The objective of the master thesis is to design and verify sufficient resistance of load-bearing construction system of main station roofing in Brno. The plan shape is irregular, maximal plan shape dimensions are around 260 x 260 m. The roof structure consists of standardised grid. The structure has variable height, roof top edge is 25,060 m above terrain. In this paper, two variants of the structure are compared.
