Design and analysis of reinforced concrete or masonry structures
Skočdopole, Jakub ; Švaříčková, Ivana (referee) ; Požár, Michal (advisor)
The bachelor's thesis deals with the static solution of the reinforced concrete ceiling slab and the inclined column of a 2-storey multi-storey building. The first part is devoted to the design of a point-supported plate, a cross-reinforced plate and an inclined column inclined by 15° from the vertical structure according to the limit state method. A spatial 3D model was created in the SCIA Engineer program, which was used to determine the internal forces in the structure. The correctness of the model results was verified by the sum of moments method. The second part deals with the study of the influence of the slope of the columns on the structure, when one row of columns in the 2nd floor was inclined and then the effect of this change on the structure and the static assessment were compared. Reference slopes chosen for the study: 0°; 15°; 30°; 50°, a partial spatial 3D model of the structure was created for each variant. The appendix of the bachelor's thesis is a detailed static calculation according to valid ČSN EN standards, drawing documentation and a study of the influence of the inclination of one row of columns on the reinforced concrete structure.

Evaluation of materials characteristics exploiting static and dynamical tests
Riesner, Jan ; Forejt, Milan (referee) ; Samek, Radko (advisor)
The project elaborated in frame of engineering studies branch M-STG describe characteristics of plasticity of non-anneal materials E 235, E 190 and E 220. Materials characteristic was receive by static and dynamical tests. Based on the literature study it was conducted survey of the current state of experimental techniques for high-speed deformation. The materials were designed by Holomon approximation of rigid-plastic material model without hardening. It was conducted force analyses for machine Unison MG 2790 for rewind bending and bend with compressive force considering the identified material model. It was describe the impact passive and active forces to move the neutral axis.

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.

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.

Bending technology profile of steel
Kameník, Tomáš ; Žák, Ladislav (referee) ; Dvořák, Milan (advisor)
KAMENÍK Tomáš: Bending technology profile of steel The project has been elaborated within the master's of studies of the subject M-STG manufacturing technology and it presents the lay-out of the bending technology profile of steel from the material S235JRG2. The bend is made by the bending and the press tools. The press tools and the bending profile were suggested on the bases of the literature study of technology bending. In consideration of the calculated bending power and the dimension profile will be made profile on the hydraulic press CYS 320 ( the manufacturer ŠMERAL Brno a.s.). At the end of the the thesis there are performed calculations of the technical and economic evaluation for the machine press and the bending .

Overpass bridge across the highway
Černý, Pavel ; Šopík,, Leonard (referee) ; Nečas, Radim (advisor)
The topic of this thesis is detailed design of the supporting structure of a bridge. Three variants are designed. The structure is designed as a single beam bridge of 6 spans. The calculation of load efects make in software MidasCivil 2019 and Scia Engineer 18.1. The subject of the expertise of the structure is service limit state and ultimate limit state. For evaluation of cross sections is used MS Excel. Both design and relevant drawing documentation of the bridge deck and substructure. The design and assessment are according to the europien standards.

Manufacturing of mirrors clamp
Večeřa, Jaromír ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
This thesis presents a proposal for manufacturing of a mirror clamp, used for wall mounting. The clamp is made of stainless steel 1.4301 with a thickness of 1 mm. Manufacture series produces 40,000 pcs/year. After considering the individual manufacturing options, production in the combined process tool was chosen. The manufacture takes place in five steps, the utilization of the material is 84.1 %. This was completely proved by technological, design and control calculations. According to these calculations, a tool was designed with all of the technical documentation. Due to the forming force of 180 kN and the work of 113 kJ, the eccentric press T-30 CE from the company SanGiacomo Presse was chosen.
