Influence of subsoil stiffness on base plate deflection
Podolák, Patrik ; Zich, Miloš (referee) ; Strnad, Jiří (advisor)
The work deals with the analysis of the deflection of the base plate, which is located on the not-known subsoil. The survey of the bedrock found unevenness of the base soil and the presence of imported soil, which is mixed with construction waste. Around the perimeter of the board there are foundation belts, and in the center there is only the mentioned foundation plate. The structure is loaded with internal load-bearing walls 200 mm thick. under which there is no foundation belt. The aim of the work is to assess possible variants of the bedrock and thus prevent possible material damage. Static load calculation will be performed manually and the subsequent design model will be performed in Scia Engeneer.

Concrete flat slab supported by columns
Járik, Enikő ; Švaříčková, Ivana (referee) ; Perla, Jan (advisor)
The aim of bachelor theses is to find out the internal forces on the point-supported reinforced concrete flat stab of a hospital buildingon the first floor.The analysis was performer using the following method: finite element method in Dlubal´s RFEM program, result were proved by the equivalent frame method. The structural assessment was performer according to ultimate and servicable limit states. The work also includes the desing of one column.

Concrete flat slab supported by columns
Lehoťák, Roman ; Švaříčková, Ivana (referee) ; Perla, Jan (advisor)
The bachelor thesis deals with the analysis of internal forces and the design of the shape and reinforcement of the reinforced concrete monolithic slab, the ceiling above the 6th floor of the University Hospital in Bohunice. The calculation of internal forces was performed by the substitute frame method and the finite element method in the Nemetschek Scia Engineer 18.0 program. The work deals with the design and assessment of the board and adjacent stairs.

Concrete flat slab of parking house roof
Pivodová, Alena ; Strnad, Jiří (referee) ; Perla, Jan (advisor)
The bachelor's thesis deals with the analysis of the internal forces of the point-supported cast-in-place reinforced slab. The slab is located between three apartment buildings and serves as roofing garage, the roof is proposed as green walkable flat roof. The replacement frame method and Finite Element Method was used for the analysis. Computational software Dlubal RFEM 5.07 was used to calculate internal forces. The slab is designed by two structural types. The thesis deals with design and check one of the types and one column.

Amplifier with Speaker Protection
Přibyl, Libor ; Schimmel, Jiří (referee) ; Kubánek, David (advisor)
The present work deals with the issue of speaker damage due to large displacement of the membrane at low frequencies. The main focus is the design and construction of the circuit to protect the speakers from this type of damage and the subsequent measurement of its parameters. The thesis includes theoretical predictions for the optimal design and implementation of the circuit. The work includes complete construction of equipment, including power supply and auxiliary circuits.

Static solution of garage floor slab
Sitta, Martin ; Požár, Michal (referee) ; Zich, Miloš (advisor)
This thesis presents the design and evaluation of a monolithic reinforced concrete slab, which is point-supported by columns with column heads. There were made two designs of this slab, one without column heads and the second was made with column heads. The simplified static calculation by hand and its results were compared with results from computer FEM software.

Multifunctional object - analysis of substructures of the structure
Pelouch, Adam ; Šulák, Pavel (referee) ; Švaříčková, Ivana (advisor)
This Bachelor thesis deals with design and evaluation local supported ceiling slab made from reinforcement concrete of polyfunctional building. The ceiling slab of the second floor was designing. Internal forces were analysed in RFEM software based on finite entity method with check of usability results by equivalent frame method. Structure was verified according to ultimate and serviceability limit states. Then the comparation of results of direct design method and finite entity method on simple slab 5X5 span.

Machine Tool Spindle Units: Active Tool Deflection Compensation
Zarboch, Jaromír ; Vetiška, Jan (referee) ; Březina, Tomáš (advisor)
Cutting forces during milling process cause tool deflection. There are several methods for compensation of this deflection. This paper is focused on the active method of tool deflection compensation which angles adaptronic spindle by piezoactuators to compensate the tool deflection. For this method the simulation model was built in programe Matlab / Simulink. The effectiveness of this model was validated by search simulations.
