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.

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.

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.

Realization of educational problem based on preloaded bolted joint apparatus
Žaba, Tomáš ; Náhlík, Luboš (referee) ; Vaverka, Michal (advisor)
In the master’s thesis an educational task concerning an experimental apparatus for quantity measurement in preloaded bolted joint is realised. In terms of its preparation an innovation of the apparatus leading to an easier and faster pretension realisation was implemented. The educational task for students and also teaching material were produced. The educational task itself consists in experimental confirmation of the relation between the tightening torque and the caused pretension. An FEM model simulating an apparatus flange deformation by given pretension was designed to verify the experiment. The thesis also contains information about the preloaded bolts, pretension elicitation methods and pretension control methods.
