Wind load on cooling tower
Ehrlich, Tomáš ; Kala, Jiří (referee) ; Nevařil, Aleš (advisor)
Thesis is concerned with modeling fluid dynamics and computing wind load on thin-walled structure of cooling tower. Two models for computational fluid dynamics are presented – one with singleton cooling tower and second with group of four cooling tower. Thesis includes also a structural model of cooling tower and methodology of wind load transfer is presented.

Wind load analysis of building structures
Ptáček, Václav ; Kala, Jiří (referee) ; Hradil, Petr (advisor)
This bachelor’s thesis is focused on wind load analysis with regard to the dynamic effects caused by wind impact on slender structures. These calculations are conducted for a chimney structure with use of various wind velocities. The thesis includes basic principles of fluid flow modeling in CFD programs like ANSYS CFX.

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.

Lookout tower
Jedzoková, Patricie ; Pešek, Ondřej (referee) ; Balázs, Ivan (advisor)
The object of the diploma thesis is design and assessment of a steel lookout tower situated in Beskydy mountains. Two different variants were designed. The first variant is of square shaped plan and the second one is of hexagonal shaped plan. Both variants are spatial truss structures. They are shaped as hourglass. The variants were compared and the first one was chosen to be further developed. The lookout tower is 36 meters high and it is divided by floors. One floor is 3,6 meters high. The widest section is 8 meters, the narrowest section is 5 meters wide. The structure is pin-supported into concrete foundation. The concrete is class C25/30. The roof covering is made of trapezoidal sheet of class S280GD. Each steel element is made of steel of class S355.

Construction Stages Analysis of a Membrane Structure with Respect to Wind Load
Zajac, Zbyněk
This paper deals with an analysis of a membrane structure loaded with wind pressure with respect to the construction stages. Modern tools allow analysis of structural response to the prestressing of membrane surfaces in the predefined sequence. So far, analytical models of the membrane structures have been simplified and the sequence of construction has been designed afterwards. This process may lead to the oversized elements, because it is not possible to estimate the structural response to the unexpected load on the structure under construction. Besides, the aim of this paper is to point out the meaning of the construction stages analysis of the membrane structures with respect to the safety on a building site.

Prestressed bridge on the expressway
Juřenčáková, Jana ; Zlatuška, Karel (referee) ; Koláček, Jan (advisor)
The purpose of the diploma thesis is to design a expressway bridge over the river Vsetínská Bečva. The bridge is located between Valašské Meziříčí and Vsetín. Separate superstructures are designed for each directions of the expressway. The right superstructure, which is wider, is considered for detailed design. Two variants were proposed, A double T beam superstructure and a box girder superstructure. The three span box girder superstructure was chosen for the design. Spans are 48+65+48 m long. Two options of construction process of the superstructure were proposed. This bridge is designed according to the limit states, the influence of construction process is considered. Structural models of construction were made as a finite element model and a plate model. Structural analysis, drawings and visualization were developed.

Roofing of Athletic Hall
Potůčková, Simona ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of this diploma thesis is a design of two versions of bearing roof construction of the athletic stadium in Brno and a smaller side roofing of changing rooms. The building has rectangular plan of dimension 67 x 102 m and the side construction has also rectangular plan of dimension 61x 8 m. The minimum height is given by requirements of various athletic sports. Material used for the main construction is steel strength class S355 and for the side construction it is steel strength class S235. All the calculations are according to valid norms ČSN EN.

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.
