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.

Bridge No. 203 on the highway D1, Považská Bystrica
Mudrík, Marián ; Štrba, Michal (referee) ; Karmazínová, Marcela (advisor)
The diploma thesis deals with alternative design of bridge on highway D1 near Považská Bystrica. Bridge is designed as composite steel-concrete bridge with 6 spans in length 35,7m + 42m + 42m + 42m + 42m + 35,7m. Overall length of superstructure of the bridge is 241m. Construction material used in design is steel S355, concrete C35/45 and reinforcing steel bars are grade B500B. Calculation of superstructure of two variants was performed in preliminary design. First variant is twin-girder structure system and box-girder structure system is second variant. Selected twin-girder bridge was developed in more complex structural design report. Direct erection in place with temporary piers was selected as assembly method of steel structure. Slab concreting will be done by mobile formwork. The design and calculation of the bridge structure was carried out according to valid European design codes. The diploma thesis includes engineering report, structural design report of variants, structural design report of final variant, bill of quantities of assembly parts and drawing documentation.

Steel hall structure for industrial production
Bém, Miroslav ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of the bachelor thesis is design and assessment of the double aisle steel hall structure for industrial production in Moravské Budějovice. The hall has rectangular ground plan and it is 30m (18 m and 12 m) wide and 56 m long. There is trolley crane inside in the buinding with a lifting capacity of 12,5 tones. The main bearing components are trusses, solid poles, bracings and thin-walled purlins.

Railway Bridge on the Track...
Kováčová, Zuzana ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of the diploma thesis is the design and check of the supporting structure of the railway bridge on the line Brno - Česká Třebová. The bridge carries a double-track railway line across Šámalova Street in Brno. The span of the bridge is 16.58 m, the length of the supporting structure is 17.1 m and the width in cross section is 17.81 m. Two variants of the supporting structure have been developed. The first variant is a bridge with a composite supporting structure, the second variant is a bridge with concreted steel girders. A technical report and drawing documentation are prepared for the selected variant.

Static verification and alternative design of steel structure of winter sport stadium in Jindřichův Hradec
Holec, Tomáš ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this thesis is the conversion and alternative proposal to the existing steel structure roofing the winter stadium in Jindrichuv Hradec. The building has a rectangular plan with dimensions of 80 x 52 m. The roof structure consists of lattice trusses and purlins, plotted using lattice steel columns. The other possibilities are parabolic lattice trusses and purlin with fly bracing that were designed and evaluated in accordance with applicable standards. The solution using parabolic trusses is designed on the original footprint of the structure. The distance of each bond is 8 m.

Pedestrian Footbridge across the Dyje River in Břeclav
Pham, Hoang Anh ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
This thesis deals with structural design of a steel frame footbridge with wheelchair access, which will lead pedestrian and cyclists‘ traffic over the river Thaya in Břeclav. The footbridge is a structure of one field, lightness of a bridge opening is 58,92 m and a span length is 60,25 m. A light width of an area between rails is 2,5 m. The footbridge is constructed of a truss beam cable – stayed bridge on an oblique pylon of 20,0 m length and a preloaded steel suspender. The thesis was processed according to valid standards ČSN EN.

Hall for Engineering Production
Slezák, Jaroslav ; Pilgr, Milan (referee) ; Karmazínová, Marcela (advisor)
The aim of the bachelor thesis was to design and assess a steel two-nave hall for engineering production in Rajhrad. The hall has a rectangular plan with a width of 32 m (20 m and 12 m) and a length of 63 m. The total height of the main nave is 13.5 m. One bridge crane with a capacity of 5 t and a span of 19 m runs in the hall. The building is be covered with a gable roof with a pitch of 5 %. The modular spacing of the main trusses is 6 m. The superstructure consists of truss girders, full-wall columns, bracings and full-wall purlins. The RFEM program was used to determine the internal forces on the individual structural elements.
