Design of the floor slab structure of a tall building
Vintrová, Tereza ; Šimůnek, Petr (referee) ; Zich, Miloš (advisor)
The bachelor thesis deals with the design of the ceiling structure of a high-rise building. The basis for the work was a study of the building with basic floor plan dimensions and heights. The aim of the bachelor thesis is to design a locally supported floor slab with a stiffening core in the middle, as a section of one floor, namely the ceiling above the tenth floor. According to the specified study, a slab model was created in SCIA Engineer to analyze the internal forces based on which the design of the flexural reinforcement of the slab to the ultimate limit state was carried out. The design of the shear reinforcement is based on the internal forces of the 3D model and was done using Schöck Bole with manual verification of the selected column. Non-linear calculation of the 3D model and manual verification of crack widths was used to assess the ultimate limit state. At the end of the work, the design of the circumferential rib variant and the comparison of the two types of slabs was carried out. The work includes a static calculation and drawings.

Punching technology
Králíček, Václav ; Harant, Martin (referee) ; Peterková, Eva (advisor)
The thesis is focused on punching technology, technology which can create complex-shaped parts from sheet metal. The thesis contains description of the principles of punching, emphasis is put punching tools and various production methods, which can be performed using modern punching machines. Part of this thesis is focused on comparison between punching technology and laser cutting. The comparison is shown on two different semi-finished products made from stainless steel by ACO Industries k.s. These semi-finished products are compared from the point of view of production accuracy and manufacture speed.

Experimental Investigation of the Influence of Openings Orientation on the Punching Resistance of Flat Slabs
Kormošová, Ľudmila
The article deals with experimental investigation of the influence of openings orientation on the punching resistance of flat slabs. Within the experiments, two isolated fragments of flat slabs were tested. Both specimens were weakened by two symmetrically placed openings with dimensions of 240 mm × 150 mm adjusted to the shorter side of the elongated column with cross-section of 950 mm × 150 mm. The specimens differed from each other by the orientation of the openings in relation to the support. In addition to the comparison of deformations, the actual control perimeter lengths of the tested specimens were calculated based on the results. Compared to the theoretical lengths of the control perimeters according to EC2, the reduction of the control perimeter appears to be conservative.

Structure of multi-storey building
Achillesová, Jana ; Klodner, Jan (referee) ; Perla, Jan (advisor)
This diploma thesis deals with the project of the structure of ferroconcrete multi-storey building. Selected parts for assessment are point-supported slab over the 1st floor, inside column, external and internal wall in the 1st floor. Finite Element Method in software Dlubal RFEM 5.23 was selected for the analysis. Another part of the thesis is the project of dimensions of foundations that are dealt with as deep foundations in accordance with engineering-geological survey.

Production of supporting plate
Filip, Jiří ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of technology for production of supporting plate, which is a top part of a service trolley, serving for manipulation with switch of high voltage. The supporting plate is manufactured of low carbon, deep drawing steel DX51D+ZM thickness 2 mm and quality according to EN 10346. Annual serie was set for 200 pieces. In evaluation of production possibilities were chosen technologies of punching and bending. There was designed unfolded shape of the sheet metal with dimensions 1068 x 900 mm and created cutting plan. As was found, from one metal board is possible to cut out 2 pieces of the supporting plate, while 70% of material use. In the next step, punching tools were chosen and manufacturing process was made. The highest achieved cutting force was 122,8 kN. The chosen machine is hydraulic CNC press TruPunch 5000. For bending there was created a bending plan, according to which bends will be made in thirteen steps. Used bending tools are punch OW209/S and two types of matrix EV005 + FWZ and EV006 + FWZ. Maximal achieved bending force is, according to the calculation, 259,8 kN. Bending operations will be made on CNC press TruBend 5130. In a technical and economical evaluation was determined cost for the material, which is 57 337,5 Kč.

Bridge over the Jevišovka river
Čípek, Luboš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
This thesis focuses on design and assessment of load-bearing construction of a bridge over Jevišovka river at road I/53 near Lechovice. The bridge was designed as a trapezoidal cross-section slab. This solution was chosen from three sketch eventualities. The work includes an implementing engineering report, construction process report and report about static-analysis, the attachments include the sketch, vizualization, drawings, component drawing, construction process and the static-analysis of this structure. Computing of internal forces was performed by computational software Scia Engineer 17.
