Load carrying structure of multipurpose hall object
Prokešová, Pavlína ; Karmazínová, Marcela (referee) ; Melcher, Jindřich (advisor)
The aim of diploma thesis is to design and assess a multipurpose hall building in the area of Brno. The shape of the hall is rectagular with dimensions 30,0 x 84,0 m. Roofing stucture is disegned and assessed in three versiions. Variant A is designed as a sadle - type truss from the CSH profile. Variant B is designed as a square - type truss from the CHS prosile. Variant C is designed as a arched truss from the CSH profile. These versions are compared by weight, manufacturing complexity and appearance. Preferable version is processed in detail. The work also includes a static calculation of the supporting elements, joints and drawing documentation..

Static design of the crane runway - comparative calculation
Krompolc, František ; Melcher,, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The purpose of bachelor thesis is recalculation the crane runaway according to current Eurocodes (CSN EN 1991-3 a CSN EN 1993-6) comparing results with the recalculation according to previous standards (CSN 27 0103 and CSN27 0101). In the hall there is one trolley crane. Its capacities is 12,5 tons. The structure is designed for the area of city Koprivnice. The main beam 12,0 m in length is welded biaxial symmetric I profile. Heigth of the beam is 800 mm, width is 300 mm, thickness of the flange 30 mm and web thickness is 30 mm. Horizontal bracing beam is truss girder - one belt is the upper belt of the main crane beam and second one is made from the half of HEB 140 profile. On the horizontal truss girder there is revision footbridge. Diagonals 1803 mm in length are designed from L70x70x7 profile. Vertical beam length is 1000 mm and is made from L50x50x5 profile. Length of truss is 1500 mm. Free belt of horizontal truss is supported by angled bars , which are connected to upper belt of the main crane beam, creating a fulltruss system in oblique level.

Hall for Metal Production with Administrative Building
Kaňok, Vojtěch ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
This diploma thesis deals with the design of a metalworking shed with its adjacent administrative center. Both objects are statically independent. The buildings are located in the town of Bučovice. The dimensions of the shed are 54,78x72,58 m. There is an overhead crane situated in the middle wing. The shed‘s height is +11,62 m. The administrative building has L-shaped plan. Its dimensions are 27,62x8,13 m (the wider part is 15,63 m). The design of the administrative object has two variants. Both variants have composite steel-concrete ceiling structure. The heights of the objects are +11,20 m (A variant) and +18,20 m (B variant). For the A variant, drawings were also drawn up with the design and assessment of structural details and anchoring.

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.

Static verification and variant design of steel structure of administrative building of Gasworks in Brno - Radlas
Štulrajterová, Terézia ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this master´s thesis is a recalculation of the existing structure, design, static analysis and economic comparison of two variants of this bearing structure of the administrative building Jihomoravská plynárenská located in Brno. Ground plan dimensions and height of both these variants are based on existing disposition of the building. The diameter of the circular floor plan is 16,088 m and height of the structure is 29,46 m. With this new proposal of solution A and B, lower weight of structure in comparison to the existing state has been reached. Both variants have a bearing column in the middle of floor plan and new solution of ceiling structure. The most advantageous from the economic and assembly point of view is variant B. Design of this variant was processed in detail.

Terminal of Brno International Airport
Jančar, Ondřej ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of the diploma thesis is make a structural design of load carrying steel structure of terminal international airport Brno. The project is designed in two options. The height of the building in highest point is 15 m. The object has rectangular ground floor plan with proportions of 80 x 40 m. For selected option the check of joints and anchorage is performed as well as the design drawings. The object was designed according to currently valid standarts to the ultimate limit states and serviceability limit states.

Steel-Concrete Columns Composed of High-Strength Materials
Röder, Václav ; Štěpánek, Petr (referee) ; Studnička,, Jiří (referee) ; Vičan,, Josef (referee) ; Karmazínová, Marcela (advisor)
The main objective of this thesis is the verification of the buckling strength of the composite compression members which were made from high-strength materials. This thesis is divided into four main chapters which are interconnected. The first chapter summarizes the current state of the problem of the compression members. The basis of this part is the elementary theories and researches, the task of this text is attempted to understand and obtain normative procedures which are important for practical use. The second part deals with the theoretical analysis of composite column, mainly with the examination of the individual effects on the buckling strength. The result of the first and the second parts is analytical algebraic equations which determine the buckling strength of the member. The third part contains the numerical analysis, which leads to create a numerical model of the compression column. The numerical model is used for the verification of the theoretical analysis and for the investigation of the behaviour of the column loaded by axial force. The last part deals with the experimental verification of the previous analyses. There are tested various types of the composite columns, which were made of steel with a yield strength up to 455 MPa and of the concrete with a cube compression strength up to 102 MPa. Experimental results confirmed the high reliability of centrally loaded column and every tested columns failed by flexural buckling. The final step is evaluation and comparison of the results obtained from previous four parts. It was founded that design criteria for centrally loaded steel-concrete column are too conservative and design relationships doesn´t use the positive properties of high-strength materials for economic design.

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.
