Restaurant dance floor shelter
Horský, Vojtěch ; Šmak, Milan (referee) ; Barnat, Jan (advisor)
In my diploma thesis I designed 2 options for an arch roofing of place for dancing next to the restaurant in Dolní Jablonná. The first solution was designed as a timber structure with internal supporting arch from glue laminated timber. The second solution was designed as a two pin-supported steel beam. These variants were predesigned and as the final solution was chosen the timber structure. I designed a rafter, a glue laminated arch, a purlin, an anchorage and field joints. The thesis is including drawings of the layout design, details and anchorage plans.

Engineering optimization of a bolted joint under cyclic load
Pavlíček, Tomáš ; Kubík, Petr (referee) ; Vosynek, Petr (advisor)
This bachelor’s thesis deals with improving the service life of a cyclically stressed screw connection. In order to correctly determine the tension amplitude in the screw, it is necessary to know exactly the stiffness constant of the connection C. In this work, a comparison of analytical approaches for its calculation was made for a connection with a screw-in head screw. Based on a comparison with the numerical solution, it was evaluated as the most accurate approach according to the VDI 2230 standard. Furthermore, the influence of the size of the preload value on the life of the screw was assessed. It was found that the optimal value of the preload corresponds to the state when the clamping of the connected parts is lost. The last part of this work was focused on structural modifications that will improve the service life of the joint. The following design modifications were assessed: flexible screw, large area and spacer washer. The most significant increase in service life was achieved using a spacer washer.

Steel lookout tower
Šenk, Josef ; Pešek, Ondřej (referee) ; Horáček, Martin (advisor)
The aim of the master thesis is a design and an assessment of a steel construction of a lookout tower. The lookout tower is located on the top of a hill near to village called Senetářov. There were designed two different options. The first one has a plan in the shape of hexagon, which is rotated on each floor. A plan of the second option is in the shape of rotational hyperboloid. Both options were assessed and compared, and the first option was chosen to be developed in greater detail. The total height of the lookout tower is 31,2 metres and the maximum dimension of the plan is 6,9 metres. The whole construction of the lookout tower is designed from steel grade S235 J2.

The design of hinge on bus technical and luggage compartments
Daněk, Lukáš ; Tůma, Jiří (referee) ; Knoflíček, Radek (advisor)
The bachelor's thesis deals with the design of hinge for the doors on bus technical and luggage compartments. The theoretical part is focused on the types of hinges and their capabilities. The practical part deals with the design process, including system analysis using calculations and measurements. A solution universally applicable on different door sizes is proposed, which also meets the requirements for water drainage and door adjustment. The final assembly is optimized by calculations. Benefits and impacts are evaluated.

Steel structure of lookout tower
Pavlas-Jirásek, Václav ; Horáček, Martin (referee) ; Balázs, Ivan (advisor)
The diploma thesis deals with the design of a main load-bearing steel structure of the lookout tower with the height 35,5 m. Two different types of solution were designed. The first design is a spacial truss structure and the second design is a fixed solid cantilever. The first solution was chosen to be further developed. The truss structure has square plan that varies with height. The width is 6,6 m in the level of supports and 3,6 m in the narrowest section. Main bearing members are five pin-supported columns. The base material is steel of class S355.

Rally team base
Mikeš, Daniel ; Horáček, Martin (referee) ; Pešek, Ondřej (advisor)
The object of the diploma thesis is the design and the assessment of the steel structure for rally team base in Napajedla, which contains the space for the administration and the space for the service hall. The overall ground plan proportions of the structure are 30 x 26 metres. The structure for administration is the four-storey building. The ground plan proportions of this structure are 30 x 12 metres and the height is 14.5 metres. The ground floor grid of the main load-bearing structure is 6 x 6 metres. The height of the one floor of the structure is 3.5 metres. The structure of ceilings and roof is designed like composite steel and concrete structure. All joints of the steel structure for administration are designed like bolted joints. The spatial rigidity of the structure is ensured by vertical wall truss bracings and by the rigidity of composite steel and concrete structure of ceillings and roof. To the structure for the administration is connected structure for the service hall. The ground plan proportions of this structure are 30 x 14 metres and the height is 10.5 metres. The main structure of the structure for service hall is frame with the rigid joint in the corner of the frame. The axial distance of the main structures is 6 metres. All joints including the rigid joint in the corner of the frame of the steel structure for service hall are designed like bolted joints. The spatial rigidity of the structure is ensured by vertical wall truss bracings and horizontal roof truss bracings. The whole structure is designed of steel S355.

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.

Steel construction of an exhibition pavilion
Wawreczka, Karel ; Šmak, Milan (referee) ; Štrba, Michal (advisor)
The aim of diploma thesis is to design steel roof structure of minimum dimensions 45 m x 50 m and minimum height 12 m. The plan of the building design has dimensions of 52,14 m x 70, 00 m and height is 18,68 m. The roofing was design as 3D truss girders with two lower chords and one upper chord. The shape of 3D truss girder consists of three circular arcs of radius 69,88m, 12,43 m and 33,45 m. Between main girders is 3D bracing. The structure is pin-supported.

Bolted joint of turbocharger and cylinder head
Kolivošková, Veronika ; Píštěk, Václav (referee) ; Novák, Kamil (advisor)
The subject of this diploma thesis is the theoretical basis of the screw connection theory and the subsequent application to the specific screw connection problem. Mentioned connection is part of the turbo charged combustion engine, specifically directly between the cylinder head and the turbocharger. The diploma thesis is divided into several parts. The first part dealing with selected chapters of the screw connections and the combustion engines theory, whose knowledge is important for further chapters of this diploma thesis. The next part shows method of creating the geometric and computational model, on which were performed the appropriate sensory analyses with respect to determine the cause of the nut and bolt loose in the given connection. On the basis of the gained knowledge and their evaluation has been created a separate calculation methodology in the last part of this thesis, which describing parameters that have an impact on this undesirable phenomenon, and which should be included in analyses for similar issues. The diploma thesis was realized in cooperation with ŠKODA Auto a.s., tř. Václav Klementa 869, Mladá Boleslav, and AUDI AG, Union-Straße 1, Ingolstadt.
