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.

Load-carrying structure of assembled family house
Návarová, Michaela ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this thesis is the static design of load bearing structure of a flat-building. The flat-building is designed as a two-floors building with cock-loft. The ground plan of the house is 15,04 x 16,74 m, the height is 9,25 m. The house is considered as II. snow area and II. wind area. The load bearing structure is designed in two variations. In first variation is designed load baering structure of the house by steel thin-walled sections, in second variation is designed by timber sections. In both variations load bearing structures is made of columns, garlands, ceiling beams and roof truss.

Static verification and variant design of roof structure of winter sport stadium in Znojmo city
Kovář, Jindřich ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of the thesis is the conversion and alternative proposals for the existing steel structure roofing winter stadium in Znojmo. The building has a rectangular shape with dimensions of 84 x 63 m Roof truss structure is formed purlins and trusses girlandovými, vynášenými two steel arches with a span of 84 m variant solution is full board and reduced lattice truss plate. After evaluating both solutions was chosen the first option, which was subsequently designed and assessed according to applicable standards. Truss plate is designed on the original footprint supported the original concrete bearing walls. Eye lattice plate is a square with sides of length 3.5 mA at 3 m Joints are designed truss balls and anchoring pin.

Static verification and variant design of roof structure of winter sport stadium in Jihlava city
Bulíček, Radek ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of the thesis is the assessment of steel structure roofing winter stadium in Jihlava city and design of the variant solution of load bearing steel structure of the roof. The ground plan dimensions are 60 x 84 m The current structure is composite of truss main girders with parabolic lower chords, and purlins . Axial distances of main girders are 12 m and are supported on concrete columns. The alternative proposed solution uses arched truss main girders and truss purlins. They are supported on existing concrete columns. All load bearing members of existing and new design structure – main girders, purlins, roof bracing - have been evaluated according to actual normative rules. It is evident that the static assessment of the existing structure is satisfied from viewpoint of ultimate and serviceability limit states. The static assessment of the new structure is satisfied from the viewpoint of both limit states.

Steel structures of boiler and engine rooms
Krompolc, František ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
A steel construction, divided into two parts, was designed for the building object of a production block of a bio power plant. The two parts separate the boiler room and the engine room. Due to the specific load caused by the operation equipment, also several plateaus, consoles, footbridges and technological constructions were designed. A system of principal pillars HEB, transversely frame-connected with plane solid girders IPE, forms the hall construction. Pillars in rows 1 and 4 are rigidly jointed to foundations. A bearing structure of the roof deck is imposed on the girders. It is composed of a system of purlins – rolled profiles type UPE. The rigidity of the roof is secured by horizontal bracing between the purlins. The construction of the boiler room is attached to the construction of the engine room, which is formed of frame-connected principal pillars HEB in rows 4,7 and 8. The roof truss IPE is designed for 12 900 mm span between rows 4 and 7 and for 4 800 mm between rows 7 and 8. The spatial rigidity of the structure is not only secured by the rigid connection of pillars and foundation combined with the frame-connected roof rungs. It is mainly maintained thanks to the system of vertical wall bracings interacting with the horizontal bracing of the roof. Between the pillar rows B, C, D, E, F and G and 8 to 9 a construction of a substation is attached. In the engine room is situated technological structure. The construction is formed by supporting frames consisting of pillars type HEA, rungs type IPE and HEA and vertical bracing of rolled profiles. Pillars type HEA are connected to foundation using articulated connection. The rigidity of the structure is secured both ways by vertical bracing and by the connection of the plateau beams with the hall girders.

The two-track railway bridge
Loučka, Miroslav ; Karmazínová, Marcela (referee) ; Puchner, Josef (advisor)
Master´s thesis describes the design of the railway bridge in Ústí nad Labem. Length of the structure is 200.00 meters, the height of the structure is 32.61 m and width of the structure is 12.10 m. Main structural system is composed of a spatial strut-frame structures. The bridge carries an important railway stations between Usti nad Labem Západ, Usti nad Labem Střekov. Part of the proposal is a footbridge for pedestrians.

Roof structure of sport stadium
Pijáčková, Jana ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this thesis was to develop a conversion and a variant of the existing steel structure roofing ice rink in Třinec. The building has a rectangular plan on pages 90 m x 60 m, minimum headroom inside the building is given with regard to the requirements of operation. The roof structure is stored in steel and concrete columns around the perimeter at a distance of 7.5 m. Variant solution for the design of new steel roof structure was chosen arc grate. The design consists of 13 main arc lattice girders in the transverse direction for a distance of 7.5 m in the longitudinal direction of the structure consisting of planar lattice strips (girders) and purlins. All this is complemented by a reinforced system. Two dimensions are retained.

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.

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.
