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.

Laser welding of steels in automotiv industry
Paleta, Petr ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
In the automotive industry is beginning to replace the resistance spot welding by laser welding. The bachelor thesis was an analysis of laser welding methods, especially the method of remote welding, which is used for the experiment. Furthermore, the use of laser welding was described. We have also suggested the general technological process of welding. The experimental part was carried by metalografic cut of welded sample, which was evaluated by its macrostructure and microstructure.

Engineering design of conveyor
Chmelík, Jiří ; Čípek, Pavel (referee) ; Foltýnová, Dana (advisor)
The bachelor thesis deals with the design of a conveyor for transporting welded beams with variable dimensions. At the beginning of the work are listed some conveyors, which are commonly used in practice. Following analysis of available design solutions, design designs of equipment, their description and based on comparison was chosen the most suitable design solution. In the course of work is performed safety analysis of selected nodes. At the end of the work is evaluated the whole construction and elaborated the drawing documentation of the device. The proposed solution can also be used to transport parts of similar shapes.

Welding of reinforcing steel bars
Bogar, Radek ; Geryk, Pavel (referee) ; Kubíček, Jaroslav (advisor)
Radek Bogar: Welding of reinforcing steel bars Bachelor's degree Bachelor thesis, 2010/2011, FSI VUT Brno, Institute of Engineering Technology, Department of welding and surface treatment, a course in B-STI Mechanical Engineering degree program B3S-P Engineering, May 2011 str. 49, obr. 42, tab. 12, annex 2. This thesis, developed in an undergraduate degree in mechanical engineering, is focused on the manufacture and welding of reinforcing steel bars, especially for individual types of structural welds, welding methods to be used, production testing and evaluation. The work consists of literary studies of the theoretical foundations of the production of concrete and welding steel bars, their design and use for purposes of concrete structures. Part of this work is the suggestion of additional material and WPS.

The roof structure of a storage area
Kuběna, Kamil ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
My task was to design and consider the carrier of steel structures for roof storage area in Brno, so that the structure meet all the requirements for buildings and fulfill its function. Roofing, with grand-plan dimensions 50 x 20 m clear height of 4,5 m. Cross sections of the main elements were proposed and considered and also selected joints and details of the structure. Assigned drawings are included in attachments of the thesis.

The Pulse discharge welding applications and weld analysis
Kocák, Tibor ; Molliková, Eva (referee) ; Jan, Vít (advisor)
Theoretical part of this bachelor's thesis contains overview information about special welding technology, which uses capacitor discharging. Pracitcal part is about experimental attempts showing the application of the theory of welding using capacitor welder with specific settings, preparation and rating samples. Microstructure of the samples was evaluated by standard metallographic techniques.

Airport Departure Hall
Čech, Ondřej ; Šmak, Milan (referee) ; Barnat, Jan (advisor)
The bachelor thesis deals with the design and assessment of steel load bearing structure of the departures hall of the airport. It is a purlin system consisting of sloping trusses of curved shape with overhangs that make up the awning above the entrance to the building. Truss to span 18 meters is welded from pipes. The steel used in the project is S355. For the design was used Scia Engineer software, in which was created a spatial model of the structure.

Trade House in Brno
Serbousková, Kateřina ; Sýkora, Karel (referee) ; Barnat, Jan (advisor)
The final thesis deals with the design of the steel loadbearing structure of the shopping center situated in Brno. The built-up floor area is 1973 m2 (L-shaped ground plan with dimensions 48 m x 50 m). The construction consists of three parts. Building A has four above-ground floors and reaches a height of 25.5 m. The steel structure of mono-pitched roof is designed in two options. Both options consist of full-length purlins and truss girders. Building B is a single-storey building with a mono-pitched roof top reaching 8.1 m high. Building C is three-storey with a flat roof. The first floor has a construction height of 4.5 m and the remaining two floors reach height of 3.6 m, which coincide with building A. The steel structure is made of steel-concrete composite ceilings and pin-supported columns. In the case of bracings, pressure was eliminated by means of non-linearities.The work includes proposal, assessment of the supporting structure and calculation of the directional details. Internal forces were determined based on a static analysis in the SCIA Engineer calculation program.

Glazier's Hall
Kelar, Petr ; Pilgr, Milan (referee) ; Barnat, Jan (advisor)
The bachelor's thesis deal with structural design of Glazier's hall. Dimension of the hall are 9,24 m x 24,51 m. The basic material is steel S355. The main frame is three-hidged frame. Each frames are connected by the purlins and girts. Spatial rigidity of the structure is provided by the rigid frame corners and sway bracings. Part of the design is crane runway for bridge crane from Demag company with load capacity of 5 t. Structure i designed in compliance with valid standards of ČSN EN and corresponds with ultimate and serviceability limit state. For structural design was used software RFEM 5.07.03 of Dlubal company.
