Static design of the structure composed of combination of steel and structural glass
Potůčková, Simona ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The objective of the bachelor thesis is to design the load-bearing construction system and its cladding made of a combination of steel and structural glass and to verify its sufficient resistance. The object has rectangular floor plan with dimensions of 7,5x10,5 m and and its total height is 24,5 m. The building is located at the suburban area of the city Ostrava, precisely Ostrava Poruba. The construction is composed of a ground floor and six upper floors. The main load-bearing system consists of steel frame formed by six tubular columns connected beams and sway bracings ensuring the spatial rigidity of the structure. The object was designed according to currently valid standards using ULS and SLS verification.

Reliability Analysis of Steel Columns with Encased Web in High Strength Concrete under Compression
Puklický, Libor ; Krejsa,, Martin (referee) ; Melcher, Jindřich (referee) ; Kala, Zdeněk (advisor)
The presented paper deals with a theoretical analysis of the ultimate limit state. The results of experimental research carried out at the Institute of Metal and Timber Structures headed by Assoc. Prof. Karmazinová and Professor Melcher were applied. The geometrically and materially nonlinear solution based on the Timošenko’s solution is verified by the FEM model in the computer programme system ANSYS. The random influence of initial imperfections is taken into consideration. The FEM model also includes the influence of residual stress. In the parametric study, the influence of residual stress on the cross-section plastification is researched into, its influence on the load carrying capacity limit is, together with the influence of other imperfections, the subject of the stochastic analysis, applying the Latin Hypercube Sampling (LHS). Further on, the study proves a direct effect of the concrete part of the cross-section (combination of materials steel-concrete) on the decrease of load carrying capacity limit of the beam caused by influence of the residual stress of steel. With regard to the importance of time dependent phenomena of the concrete creep for the load carrying capacity, the studies given in the Ph.D. thesis are oriented in this respect. The parametric studies of the influence of the concrete creep having applied the Standard Eurocode 2 provide both a comparison of load carrying capacity limits when using common and high-strength concrete types, and also the variability of load carrying capacities. It follows from the comparison of the statistical analysis outputs according to the design reliability conditions of the Standard EN1990 and of the approach of Eurocode 4 that the Eurocode 4 can be recommended for dimensioning of this member type. According to the studies which we carried out, the design in compliance with Eurocode 4 can be evaluated as the reliable one. A larger set of experimental data is necessary to determine the economy.

Sports hall
Horká, Petra ; Ing. Josef Puchner,CSc. (referee) ; Sýkora, Karel (advisor)
The goal of this master´s thesis is to design load bearing structure of a sports hall. The thesis is elaborated in two variants of the structure design of the sports hall for common types of sports (handball, footsal, tennis, volleyball, basketball). The ground plan dimension is 42 to 72 meters and the construction height is 8 meters. The construction is designed for the district of Brno city. In the structural anlysis there were the following main load bearing structural elements designed and examined: glue laminated timber truss, wood purlins, steel beams, rods and bracing, columns, which together with the transverse girders are linked and foot and anchoring. The selected variant is also further developed. Part of the work is drawing documentation of the choosen variant, disposition drawing and drawings of the selected details.

Removing of masonry wall at block of flat
Kollárik, Adrián ; Šulák, Pavel (referee) ; Strnad, Jiří (advisor)
The Bachelor Thesis deals with the removal of a brick partition from an apartment building. The goal of the thesis was to find multiple ways to remove the wall – it is a complete removal and replacement of the wall with a brick partition. The thesis consists of technical report, structural analysis, and drawing documentation. The technical report describes the current state and the proposed solutions. The structural analysis deals with the load and bearing resistance of the designed structure. The drawing documentation is implemented based on the structural analysis.

The superstructure of the apartment building
Kollárik, Adrián ; Bažant,, Zdeněk (referee) ; Strnad, Jiří (advisor)
The diploma thesis deals with superstructure of apartment building in brno, which is located in a row house construction. The goal of the diploma thesis is to design new supporting structures and minimize the load from these construction because of low reservs in the load capacity of the existing supporting walls. the thesis contains a technical report, analysis of statics, drawing documentation and visualization. The internal forces were executed by software scia engineer.
