Multi-storey building
Zaikin, Danil ; Bajer, Miroslav (referee) ; Bukovská, Pavla (advisor)
The subject of the thesis was the design of a multi-storey office building. In the transverse direction the building was designed as a three-tract 6.0 + 4.0 + 6.0 = 16 m. In the longitudinal direction 9x6.6 m = 59.4 m. The design was designed in several variants: articulated and frame in transverse directions. The joint variant was selected for detailed analysis.

Deriving and Application of Analytical Design of Hammerspring in Firearms
Vobejda, Radek ; Polzer, Stanislav (referee) ; Slažanský, Martin (advisor)
The thesis deals with inference of analytic relations for calculation of pressure helical coil spring and considerates usage possibilities of simplified relations. In the thesis there is introduced analytic computation of slightly curvatured rod theory completed by finite element method calculations. The thesis describes two springs of firearm, which weren’t able to achieve required functionality. After this there was created a plan of concept particular spring on the base of derivated relations, which should be able to meet operative conditions.

Superstructure of the backpart of the family house
Jetmar, Ondřej ; Šulák,, Pavel (referee) ; Strnad, Jiří (advisor)
The thesis accommodates a design of a slab made out of reinforced concrete. On one side, the slab overhangs the load-bearing mansonry. The thesis comprises two solutions. In the first solution, the overhung part of the slab is not supported while in the second solution is this part locally supported by pillars. The thesis contains two variants of the slab design and also evaluation of the results.

Design of concrete structures with FRP reinforcement
Januš, Ondřej ; Girgle, František (referee) ; Štěpánek, Petr (advisor)
The diploma thesis presents design of construction with FRP reinforcement. Including design process of cross-section with FRP reinforcement exposed to bending moment and shear force at ultimate limite state according to given standards and guidelines. Long term physical and mechanical properties of FRPs are taking into account. There are also compared load capacities of cross-section exposed to combination of bending moment and axial force, which were designed according to mentioned standards. In another part of diploma thesis there is a design of construction (precast gatehouse) with FRP reinforcement and steel reinforcement with ordinary and lightweight concerete.

The Steel Structure of Car Showroom
Buchta, Vojtěch ; Buchta, Stanislav (referee) ; Hron, Lukáš (advisor)
The task of the thesis was to design a draft and a review of car’s showroom supporting structure. The object is located in the city of Hradec Králové. Floor plan has a size of 30 x 15 m, the height of the object is 7 m at the highest point. The mono-pitched roof is formed by two parts on the same slope 3.81 °. Material of all components is steel S235. All calculations were performed in accordance with valid standards. The structure consists of a load-bearing columns fixed to the ground, the truss girders are designed of hollow cross-sections, pin-suported by the columns. The purlins are pin supported by upper chords of a truss girder, with the lower and upper edges flushing. Purlins support the roof made of roof-panels by Kingspan, thickness 160 mm. Wall casing the technical parts of the object is formed also by system panels by Kingspan. The cladding of the sales area is made of glass panels by Reynaers.

Steel structure of industrial hall
Pavlas-Jirásek, Václav ; Horáček, Martin (referee) ; Balázs, Ivan (advisor)
The bachelor thesis deals with the design of a main load-bearing steel structure of industrial hall with two overhead cranes. The floor plan dimensions are 24 × 60 m, height of building is 16 m. The main structure consists of pin-supported symetrical truss girders on columns with centre to centre spacing 12 m. The truss purlins are pin-supported on the girders. The columns are fixed in the lateral direction. Spatial rigidity of the structure is secured by system of bracing. The base material is steel of class S355.

Change of voltage at LV terminals of a MV/LV power distribution transformer caused by changes in its load
Jandora, Jiří ; Bátora, Branislav (referee) ; Blažek, Vladimír (advisor)
The thesis deals with the use of distribution transformers, their integration into the electrical network, their properties, and principles and means of regulation according to changes in load. The introductory chapter is devoted mainly to the theoretical background concerning the functioning of the transformers. Even though it is not the focus of this thesis, a brief summary of their structure will be provided because it is presumed that not all the readers are familiar with this particular electrical network block and thus they should be explained how the transformer works. Then the ways of transformer regulation will be outlined. In the theoretical part, the important point for the reader is the substitution of the transformer by two-port network i.e. the equivalent circuit. The two-port network is a substitution of the connection properties by simple electric elements, which are not so problematic for further use. When dealing with the two-port networks in the chosen equivalent circuit, Blondel’s constants will be used. Blondel’s constants facilitate working with the basic network invariables of the circuit such as amperage, voltage and power. The second part of the thesis is devoted to solving a problem that involves the use of distribution transformers. The problem is as follows: there is a manufacturing plant with three transformers, each of them having rated power and nominal transformation ratio. The manufacturing plant is supplied by HV three-phase line with rated voltage and parameters given by the distribution point, where constant voltage is maintained. The task is to determine in what ways the voltage of the low voltage terminals of the transformers will change when changing the power from idling circuit to the rated load. The power factor should be constant. The method for solving this task has already been outlined in the theoretical part. The results are summed up in a simple chart completed with diagrams, which concisely describe the result of the research.
