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.

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.

Static verification and alternative design of steel structure of winter sport stadium in Znojmo
Strnadlová, Kateřina ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this thesis is the recalculation and alternative construction design of roofing winter stadium in Znojmo. The building has a rectangular plan with dimensions of 84 x 63 m. The existing roof structure consists of truss purlins and main truss with parabolic chord, which are carried out by a pair of steel arch with a span of 84 m. The new design is processed in two options. The first option is the structure formed by triangular arch truss girder with truss purlins. The second option is a steel lamellar vault formed by vierendeel beams. After evaluating the design options was for a detailed solution chosen the first option.
