Dynamic analysis of an in-line arranged cylindrical chimney
Harazim, Petr ; Kanický, Viktor (referee) ; Salajka, Vlastislav (advisor)
The diploma thesis deals with the response of a steel smokestack structure to wind loads. A detailed computational model implementing the finite element method was created in accordance with the available drawing documentation. The new smokestack was placed next to an existing one, thus it can be assumed that these two structures will affect each other. The thesis also elaborates on the problems of aerodynamic and aeroelastic stability of the earlier smokestack; in particular, the occurrence of vortex shedding in resonance with eigenfrequency of the structure, with the use of the program ANSYS CFX. The evaluation of the structure includes survey of the strength and deflections of the structure. The calculations are in accordance with valid ČSN EN norms.

Reinforced concrete structure of the cooling tower
Vostal, Lukáš ; Švaříčková, Ivana (referee) ; Šulák, Pavel (advisor)
The content of the bachelor thesis is structural analysis of cooling tower fundamental construction. Modeling of the computational model and the calculation of internal forces of cooling tower fundamental construction in Scia Engineer. The reinforced concrete parts of the structure are assessed at the ultimate limit state and the subsoil is assessed at serviceability limit state. Part of the thesis is also the desing of the reinforcement of the foundation structure and processing of the drawings.

Analysis of The Effects of Wind on The Steel Ventilated Facade
Kloss, Tomáš ; Žák,, Antonín (referee) ; Hron, Lukáš (advisor)
This master´s thesis analyzes an effect of wind load on the ventilated facade claddings. The analysis is performed on the various types of facades, from unventilated to ventilated facades with a different geometrical arrangement of facade shell. The theoretical part describes the basic knowledge about the theory of flow, turbulence modeling, determining an optimal domain, verification of the calculation model and user interface in the ANSYS software. The final part compares the value of the wind load reduction depending on the change of the gap widths and the size of ventilated spaces. The resulting values are obtained by CFD simulations. The thesis includes a design and an assessment of the steel hall construction.

Comparison of FEM softwares
Tačner, Jan ; Kratochvíl, Ondřej (referee) ; Kika, Ondřej (advisor)
The aim of bachelor thesis is to compared static programs SCIA Engineer and ANSYS, working on finite elements method. For clarity, in both programs there is modeled the same tower structure with a defined load - depending on the chosen design, character and location of the building. Programs are compared in terms of both the user ie work with its own program), and of quality received numerical and graphical outputs.

Analysis of adhesion of waterproofing systems of self-adhesive asphalt felts
Kerekanič, Robin ; Žák,, Antonín (referee) ; Žižková, Nikol (advisor)
This diploma thesis focuses on the adhesive of asphalt felts on flat roofs. The practical part evaluates on the basis of experiments the adhesion of self-adhesive asphalt felts on conventional system with warm deck. It proposes and experimentally verifies the method for temperature cycling of samples and the system for causing condensation under bitumen sheet. The influence of temperature and humidity on the adhesion of the bitumen sheet during the realization, the subsequent effects of these influences as well as the condensation test are monitored by static loading. The influence of the dynamic load on the adhesion of the waterproofing to expanded foamed polystyrene is also tested. In the discussion and conclusion, the influence of the human factor on the resulting adhesion and the suitability of the methods used are also assessed.

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.

Steel Structure of Footbal Grandstand
Kloss, Tomáš ; Pilgr, Milan (referee) ; Hron, Lukáš (advisor)
The aim of this bachelor´s thesis is to design and check the football grandstand roof construction with ground plan dimensions of 30 x 105 m and a height of 20.5 m. Climatic loading is determinated for the location of the construction site - Ostrava. The resulting structural system was chosen spatially co-composed of trusses, purlins trusses, transverse and longitudinal stiffeners, columns and struts. The shape of the roof, which commemorates the air wing, is creating difficult conditions for wrapping air currents. Parts of the work are: technical report, structural analysis of the main structural elements and selected connections and drawings. The computational model for determination of internal forces is implemented in Scia Engineer. The review is created manually according to valid European standards.

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.

Lookout tower Vršek nad Zlínem
Hanáčík, Jan ; Pilgr, Milan (referee) ; Barnat, Jan (advisor)
This thesis deals with the design and assessment of the load-bearing structure of the lookout tower. The tower is 37.45 m high with the layout in the shape of a regular octagon. The object is located within the city of Zlín. The project is provisionally drawn in two variants. Hand-static calculation, drawings and engineering report is processed only for one variant. The variants differ in the structure of staircase. The thesis is drawn up pursuant to the standards of ČSN EN.
