The use of internal composite reinforcement in the design of durable concrete structures
Koriťáková, Martina ; Januš, Ondřej (referee) ; Girgle, František (advisor)
The diploma thesis deals with processing of determining the shear strength of concrete structures reinforced with composite reinforcement, subjected to shear force, according to five different design approaches. The theoretical part of the thesis is closely related to the project FW01010520 - "Development of bent composite reinforcement for environmentally exposed concrete constructions", which is realized at the Institut of Concrete and Masonry Structures, Faculty of Civil Engineering, Brno University of Technology. The project deals with the shear strength of concrete beams reinforced with steel and composite reinforcement in various combinations. Then the load-bearing results gained within the project are compared with the values obtained by calculations according to the solved design approaches and computer software Atena Science. The second part of the diploma thesis deals with the static design and assessment of the cell structure. The cell is designed as a room inside of the medical building, where is placed device of magnetic resonance which is the reason why the cell is reinforced with non-magnetic composite reinforcement.

Apartment building
Kaňa, Josef ; Pilík, Václav (referee) ; Kacálek, Petr (advisor)
The bachelor's thesis, entitled Apartment building, deals with project documentation at the level of documentation of construction for an apartment building. The building itself is located on the outskirts of the village Holešov in the direction of the village Přílepy. New construction sites have been created in the locality and development is planned. At the time of processing the project documentation, there are no buildings in the area and only preparatory work and installation of engineering networks are taking place there. The object is of a simple rectangular shape set in the middle of the plot. Most of the areas in the building are used for housing, the rest for technical and communication facilities. All living rooms are oriented favorably to the sides of the world. The apartment building has three floors and is partially basemented by one underground floor. Flats on the first floor of 4 + KK, flats on the second floor of 3 + KK, flats on the third floor of 2 + KK. The building is designed with a transverse wall masonry system of ceramic brick blocks, based on foundation strips. The project addresses two variants of ceiling structures, namely folded beam ceilings with superstructure and monolithic ceilings made of reinforced concrete. The building is covered with a flat roof. The building uses the ETICS contact thermal insulation system in a variant with mineral wool.

Optimized design of reinforcement of concrete cross section
Hudyma, Nazar ; Laníková, Ivana (referee) ; Štěpánek, Petr (advisor)
The subject of this thesis is the optimization of design variables of reinforced concrete cross-section, especially its reinforcement. To solve this problem, it was first necessary to elaborate a search section that discusses various methods and approaches for solving the problem. The research part also includes processing and evaluation of tasks solved by other authors in available literature. For the optimization task, in the following parts both the general formulation and the detailed formulation of the partial parts of the concrete reinforcement structure optimization process are processed. As an example of optimization, a simple beam is chosen, which is subjected to bending moment and normal force one load case, where the example will be divided according to the formulation of both the function and the vector of unknown parameters (variables) defining the exact shape and properties of the reinforced concrete section. The examples will then be tested with regard to the speed of convergence and the degree of deviation between the best solutions found for each optimization algorithm used. At the end there will be a comparison and evaluation of the solution of the given task, as well as a summary of the whole bachelor thesis with reference to another possible direction in the optimization problems focused on reinforced concrete structures. In the appendices there will be a solution of selected examples.
