Non-destructive testing of gear-wheels
Krejčí, Martin ; Juliš, Martin (referee) ; Čech, Jaroslav (advisor)
This diploma thesis resolves aplication of particular non-destructive testing methods while producing castings of steel wheels and quality control of this process. There are described fundamentals of flaw detection, determination of flaw-generation cause and suggestions for optimalization of casting process and increasing of its quality.

Mixed construction of an office building
Fiala, Adam ; Zich, Miloš (referee) ; Perla, Jan (advisor)
Diploma thesis deals with analysis of a construction made of concrete and masonry. A model respecting nonlinear material behaviour of masonry was assembled in a finite element based software. Calculated results were used to analyse cracks in masonry. Next, a design of a horizontal construction was carried out - concrete slab with beams to support masonry in an upper floor.

Sugar storage tank
Kotík, Libor ; Musil, Jiří (referee) ; Zich, Miloš (advisor)
The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization of construction process. The aim of this work is to the design of the main components based on the required storage capacity tank, mechanical properties of the stored material and technical amenities.

Design of reinforced tank
Štramberský, Martin ; Sliwka, Pavel (referee) ; Zich, Miloš (advisor)
The matter of this diploma thesis is a static storage tank for petroleum substances, the study of a solution for appropriate shape of shell and its effort to dihedral for roofing, and the study of effect of the storage of inner roofs walls of the tank to the size of the internal forces. The internal walls are carried out by the method of finite elements in the engineering program Scia Engineering 2013 and on the basis of it, designing of the framing sections of the tank. There is a calculation part of the lower horizontal bias wreaths of the shell and internal supporting wall. All the components are assessed on the 1st limit state of the load-bearing capacity and the 2nd limit state of the application (emergence cracks, limiting voltage in the concrete and a prestressing steel). The existing external wall is assessed only on the marginal status load of carrying capacity. The part of diploma thesis is also drawing documentation, accompanying report and technical report. The goal of the diploma thesis was to design the tank without an occurrence of the cracks in the concrete so as the vertical wall was prestressing only in the horizontal direction and the optimal proposal roof tanks as an addition.

Roof beam in the industry hall
Šnobltová, Simona ; Bobek, Lukáš (referee) ; Klusáček, Ladislav (advisor)
The bachelor’s thesis deals with the assessment of the existing roof girder in the industrial hall and subsequent outline of strengthening this construction. The girder is located in an industrial hall in Lanškroun and its original design is dated from 1998. Nowadays, cracks appear on the girder, therefore it is necessary to reassess it according to the current valid standards ČSN EN. The girder is appraised for the ultimate limit state, thus for bending and shear, and also for the serviceability limit state, thus for the pressure limit, width of cracks and transformation. Due to the fact, that not all assessments pass, hence a suitable structure strengthening with a MonoStrand prestressing strands is designed and the construction is reassessed again. For the control of a manual calculations of the internal forces on girder, was created a structural model in a program called Scia Engineer.

Load-bearing reinforced concrete structure of a family house
Borovec, Michael ; Januš, Ondřej (referee) ; Zlámal, Martin (advisor)
The final thesis is focused on designing reinforced concrete load-bearing structures of a detached house on two floors and one basement. In the basement will be located the storages, utility room and wine bar. On the ground floor will be located garage for two cars, living room with kitchen and study. On the second floor will be located bedroon and two child’s rooms. The ceiling slab of the second floor, the ceiling slab of the ground floor, the ceiling slab of the basement, spiral staircase, half-turn staircase and walls of the first underground floor with solution as water-resistant construction. Programs SCIA Engineer 21.1 and Dlubal RFEM are used to calculate the internal forces. To varify the accuracy of the results is used manual calculation. The work includes drawings of formwork and reinforcement of the all designing structires. The bulding is designed according to ČSN EN 1992-1-1.

Monitoring of cracks in the masonry of sacral buildings
Kozubková, Tereza ; Stehlík, Michal (referee) ; Cikrle, Petr (advisor)
This bachelor thesis deals with the monitoring of cracks in masonry of religious buildings and suitable methods of measuring their movements. The first part of the thesis deals with the historical development of the selected building and the description of the structure. It then describes the methods suitable for monitoring movements in cracks and the design of a suitable methodology for monitoring similar objects. The second part of this thesis is devoted to the practical measurements of the selected object, their evaluation and assessment of the state of the structure.

Comparison of tank variants from reinforced concrete and prestressed concrete
Matuška, Vojtěch ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The diploma thesis deals with design and comparison of variants of cast-in-place concrete sewage tank made from reinforced concrete and pre-stressed concrete. The layout of sewage tank is rectangular. The tank is in longitudinal way divided into two chambers. The tank is not roofed and is partialy embedded in the ground. The design for ultimate limit state and for service limit state is made for both variants. There is focus on generation and development of cracks in service limit state. For calcuation of internal forces is used model made in software SCIA Engineer, based on finite element method. The reinforced concrete and pre-stressed concrete versions are compared in last part in term of volumes of materials needed. Also there are proposed possible savings.
