Methods of Static Buckling Analysis
Svoboda, Filip ; Eliáš, Jan (referee) ; Frantík, Petr (advisor)
The aim of this theses is to create application, which is able to calculate buckling load of structure made from 1D bar elements, using finite element method. introduction is devoted to basic principles of buckling and derivation of necessary formulas. Then are described all operations and numerical methods needed for the application. At the and is in detail analyzed few structures and results are compared with known solutions or with other applications.

Flyover bridge over the Bečva river
Pidima, Jan ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The thesis deals with a design of a highway bridge with multiple spans. The bridge is constructed for highway D1 and goes across the river Bečva close to the city Přerov. Two different solutions were carried out from which a solution with subsequently prestressed box girder was chosen. Static model and load actions were modelled in program Scia Engineer 2016.0. Design checks were done manually according to corresponding Eurocodes. Load actions from wind, uneven support settling and horizontal actions from transit were neglecte.

Highway multispan bridge over wide wally
Bobek, Lukáš ; Daněk, Ing Stanislav (referee) ; Klusáček, Ladislav (advisor)
The aim of this diploma thesis is to design and assess highway bridge. The structure is located on the D1 motorway section bridging a wide valley between the Slovak villages Doľany a Klčov. Three variants have been created – box girder bridge with transverse overhangs, a pair of girder bridge and a pair of box girder bridges. The various proposals were compared with each other. For the most valuable option is selected prestressed box girder bridge with transverse overhangs, which are supported by prefabricated concrete struts. The selected proposal was subsequently elaborated in detail, the load-bearing structure is analyzed using Scia Engineer 16. In calculating the internal forces is adjusted for the effects of construction methods, even as time-dependent analysis TDA. When designing the load-bearing structure it is considered the action of permanent load, also loading from transport and temperature. The structure is assessed for serviceability and ultimate limit states according to current standards. The bridge deck is built by incremental launching method. The principle of this method consists of building the segments in a casting yard located behind the bridge abutment. Each segment is matchcast against the previous one and prestressed to the section of structure already built. The whole superstructure is then jacked forward a distance equal to the length of this segment. This process is repeated until the bridge deck is in its final position. Chosen method of construction is very fast and efficient, to the country in the valley isn´t damage during construction.

Steel structure of a heliport
Klimeš, Pavel ; Barnat, Jan (referee) ; Štrba, Michal (advisor)
The diploma thesis concerns with the design and static analysis of the heliport steel construction, which has the height of 20 m. The heliport is situated in Prague, Na Františku as a part of the hospital. The technical report and drawings are included in the thesis as well. The thesis consists of the determination of the heliport total load (including permanent, live and climate loads) and, its implementation in the SCIA Engineer 2015.3 computer software. The stress analysis of selected rods and, joints was consequently carried out by means of the manual calculation.

Kart arena
Šik, Jan ; Bajer, Miroslav (referee) ; Barnat, Jan (advisor)
The scope of the Master's thesis is the design, evaluation and the comparison of two variations of the solution for steel load-bearing structure which is a part of a gokart areal with adjacent refreshments. The construction is composed of three structurally dependent objects. For the first construction object, there were solved the variants with a truss and a frame structure. The construction has an irregular plan. The object plan dimensions are 75 x 45 m. The built up area covers 2450 m2. The construction reaches the height of 13,2 m. The thesis contains the design of dimensions, structural analysis and the evaluation of structural members. The calculation of internal forces was made by SCIA Engineer 16.1.62 software. Attached to the thesis is the drawing documentation.

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.

Effect of selected factors on the yield and health status of cabbage, carrot and onion
Koudela, M. ; Novotný, Čeněk ; Nedorost, L. ; Kocourek, F. ; Svozilová, L. ; Brožová, L. ; Doležalová, J. ; Kubíček, M.
The presented methodology summarizes the results of field experiments documenting that the selected factors influenced the development of important diseases, namely: 1. Alternaria blight cruciferous of head cabbage (in the years 2012-2013) (caused by Alternaria brassicicola) 2. Alternaria leaf spot of carrot (in the years 2012-2013) (caused by Alternaria dauci), and 3. Blight of onion and onion neck rot (in the years 2013-2014) (caused by Peronospora destructor and Botrytis aclada, respectively). The evaluated factors were: variety, crop density (carrot and onion, only), year and location. It is necessary to take into account the earliness of evaluated cultivars that also represents an important aspect of variety resistance to pathogens. In the annex, there are diagrams showing the course of air temperature and air humidity as well as the length of moistening period of leaves at both experimental locations in Troja and Svijansky Újezd in the individual years. Changes of these variables significantly influenced, in interaction with the other factors, the development of phytopathogenic fungi on the infected plants in the individual years.
