Active Compensation of Tool Deflection
Zarboch, Jaromír ; Marek, Jiří (referee) ; Březina, Tomáš (advisor)
This paper deals with design of tool deflection compensation system for milling spindle C1, provided by company TOSHULIN, a.s. A simplified simulation model of the spindle supplemented by compensatory elements was built by using programs ANSYS, MD ADAMS, Matlab/Simulink. As action elements there were use three piezoactuators each controled by PID controler. Efficiency of this compensation system was verified based on performed simulations.

Concrete flat slab supported by columns
Turek, Jan ; Požár, Michal (referee) ; Perla, Jan (advisor)
This bachelor thesis deals with design of concrete flat slab of hospital building. The slab above the ground floor was designed. Internal forces were analysed with RFEM software based on finite entity method. Results were proved by the Direct Design Method and Equivalent Frame Method. The structural assessment was performed according to ultimate and serviceability limit states.

Design of reinforced concrete structure with respect to fire resistance requirements
Pivodová, Alena ; Klodner, Jan (referee) ; Perla, Jan (advisor)
The diploma thesis deals with an analysis of internal forces of B4 reinforced construction of an office building. Analysis takes into account interaction with subsoil and when designing structural parts of the building, different requirements for fire resistance of a structure are taken into account. A Dlubal RFEM 5.17 program was used for finite element analysis, and model functionality verification was performer by using a summation of moments method. The thesis deals with the design and assessment of a point-supported slab, column, inner and external walls.

Quantification and improvement in bridge precision measurement deflection
Hvozdenský, Petr ; Suza, Patrik (referee) ; Pernikář, Jiří (advisor)
This thesis deal with improvement in bridge precision measurment deflection for Mostní a silniční Ltd. Its goal is through analysis of process of measurment and factor location, which have fundamental influence on measurment precision. First, theoretic part, represents the company, formulates problems and goals of thesis, history of bridges, world disasters, sort of bridges measurments, bridges evaluation and questions of giant transportation. In second, practical part, problems with measurment and its evaluation are described. Results are evaluated and corrective measures and recommendation are proposed in the final part.

Design of structures with FRP reinforcement
Matušíková, Anna ; Vácha, Jaroslav (referee) ; Štěpánek, Petr (advisor)
This diploma thesis presents available FRP software for calculating load bearing capacity of the structures reinforced with FRP and compares them between each other. Furthermore theory and algorithm of my own software is presented here. Load bearing capacity of structures which are reinforced with non-metallic reinforcement and loaded by combination of normal force and bending moment can be solved by my programme. Effects of high temperatures on the concrete structures can be included in the calculation. In the second part of the thesis is calculated load-bearing capacity and deflection of the real beam reinforced with FRP reinforcement and load-bearing capacity of member with FRP reinforcement with effect of elevated temperature. This has been done using my software. Comparison of results from hand calculation and laboratory load-bearing testing is done at the end. This laboratory testing was accomplished by Institute of Concrete and Mansory Structures at our faculty.

Concrete slab roof of underground parking garage
Řihošek, Jan ; Strnad, Jiří (referee) ; Perla, Jan (advisor)
Bachelor thesis deals with the roofing of the underground parking garage with reinforced point-supported slab. The aim of the work is to find out the internal forces on reinforced slab for two of the construction variants, design and check one construction variants. The replacement frame method and Finite Element Method were used for calculation internal forces using 2D model in the Dlubal RFEM 5.17. The work also includes the design and check of one column.

Analysis of behaviour of reinforced concrete slab
Kubínek, Michal ; Bažant, Zdeněk (referee) ; Zich, Miloš (advisor)
Bachelor thesis describes the analysis of behavior of existing reinforced concrete slab, locally supprorted, ceiling in hospital including 2nd limit state. Calculation od internal forces was made by computer program SCIA Engineer. Several models were made, model with best behavior due to real construction was used for dimensioning. Each model was compared with manual calculation by equivalent frame analysis. After finding inconvenient deflection, especially due to connected construction, new design was made. Thickness of slab was increased and new design of reinforcement was made. New construction was verified for both limit states.

Examples of hyperstatic beam solutions
Linhart, Lukáš ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This work will discuss the internal deformation and resulting effects in straight beams, which are stored statically certainly indefinitely. The aim of the thesis is to develop a representative summary of selected calculations and drawings, typically stored and loaded beams, solvable in linear elasticity rods. The next section describes the methods to solve statically indeterminate beam, Castiglian´s theorem, the equation of bending lines, the method of Clapeyron´s equations. Sample solution of these methods was performed on the illustrative example.
