Agricultural hall with steel load-carrying structure
Zbořil, David ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
This bachelor’s thesis solve design of agricultural hall with steel load-carryng structure. Load-carryng structure is create frame construction from solid panel IPE beam. The girders are attached to the columns articulated. All columns are transvesely fixed to the foundation pads (in the longitudinal direction acting as articulated bearing). Roofing is made of sandwich panels, mounted on the purlins of thin-walled "Z". The building envelope is made of sandwich panels, attached with girt of the thin-walled "". The whole system is appropriate completed diagonal circular hollow section bracing, both in the transverse and in the longitudinal direction. The result of this work are static report and corresponding drawings agricultural hall with steel load-carryng structure.

The load bearing steel building structure of the gym for ball games
Bui, Trung Thanh ; Karmazínová, Marcela (referee) ; Melcher, Jindřich (advisor)
Work includes design of steel structure of the single- object sports hall , which is designed for sports activities around the city of Brno . Building plan dimensions are 30 x 48 m. The main structure is formed with the help of a planar cross ties . Crosslink forming trusses which are on both sides hinged on fixed columns . The main beam is made of trusses , which have an arch shape with the construction height max. 4 m composed of a single arc. Crosslinks are spaced 6 m . The spatial rigidity provides a system of longitudinal and transverse stiffeners . The structure is designed as a purlin . All the truss rods are tubular profile , the draft of which is made according to standards EN . The columns are made of rolled profiles HEB . As a material of bearing elements is steel class S235 .

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.

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.

Steel structure of the bridge on the road
Vlček, Radek ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The content of the thesis is a proposal of steel load-bearing structure (carrying structure of a steel) bridge of the span of 31+74+31m with the bottom bridge deck taking over the second-class road in the territory of Olomouc city. The bridge deck is created by composite steel-concrete slab with crossbars. The solution was focused on using arched construction in the middle of the bridge with different tilt of arches to the horizontal central axis of the bridge. Under the term of the solution four alternatives have been calculated. The most optimal solution was selected and processed in detail. The calculations were made in compliance with the Czech technical norms ČSN EN.

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.

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.

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.
