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.

Reinforced concrete construction of cooling tower
Zralý, Tomáš ; Buřič, Pavel (referee) ; Šulák, Pavel (advisor)
There was solved reinforced concrete cooling tower in the diploma thesis. This is a rotationally symmetrical construction. The cooling tower is concrete shell on columns. The cooling tower was solved using the finite element method, computer program Midas FEA. The work includes: calculation using the program Midas FEA, comparison of load between eurocode and foreign literature, the design of shell and columns, drawings form

Timber structure of a view tower in southeast Moravia
Vrbka, Jan ; Straka, Bohumil (referee) ; Šmak, Milan (advisor)
he master’s thesis consists of a case study of an observation tower design made of glue laminated timber and steel. There are two different tower shapes of anchored or free standing tower and these towers are compared. One of the design is chosen and elaborated into final detailing. A short review of main issues bound with the observation towers is given. The review deals mainly with loading (mainly priniples wind loads are analised) and evaluating of towers (ultimate limit states, service limit states and acceleration comfort). The height of final construction is up to 60m. The design is formed by a space lattice structure made of glue laminated timber and steel members of different class. The members are fastened mainly by means of dowel joints with slotted-in-plates . There is a light steel stairway inserted into the main structure.

Static and dynamic assessment of an outlook tower construction
Valíček, Jan ; Kala, Jiří (referee) ; Salajka, Vlastislav (advisor)
This thesis deals with static and dynamic analysis of an lookout tower construction. For dynamic analysis a computational model in ANSYS software is created. Static analysis is performed by Scia Engineer software. Both of this software use finite element method. It is also focused on wind load determination by Eurocode 1, structural factor calculation, modal analysis and vortex shedding. Verification of selected parts according to Eurocodes is included.

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.

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.

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.
