BEHAVIOR OF THE CONCRETE-TO-CONCRETE INTERFACE WITHOUT SHEAR REINFORCEMENT
Čairovič, Dorde ; Terzijski, Ivailo (referee) ; Čajka,, Radim (referee) ; Štěpánek, Petr (advisor)
Doctoral thesis focuses on behavior of the interface between two concrete layers cast at different times and without shear reinforcement. By means of both experimental and numerical analysis, some of the factors affecting interface strength have been assessed. Namely, surface roughness and suitability of different roughness parameters used for its characterization, effects of overlay mechanical properties and collateral effects of surface preparation methods. Also, different tests to assess interface strength have been investigated in detail and mutually compared. The most suitable roughness parameters have been chosen, based on its overall stability. Correlation between mean texture depth and other parameters have been defined. Results of the experimental program intended to further investigate abovementioned effects on interface strength, led to proposition of extended semi quantitative design approach and introduction of coefficient of surface preparation. Based on the extensive experimental program, correlation between different test setups, including its main advantages and disadvantages, has been presented, together with roughness characterization and failure envelope of the dimpled interface.

Reinforced concrete structure of the apartment building
Ilčík, David ; Čairović, Dorde (referee) ; Šulák, Pavel (advisor)
The bachelor thesis is aimed for design and assessment of reinforced concrete locally supported monolithic slab and one selected column of a apartment building on the ultimate limit state. Another point of this work is to develop appropriate drawings. The apartment building has four above ground floors. Assessed slab is located on the second floor a column on the first floor. Internal forces are calculated using software Scia Engineer 2013. The Results of the software are compared with the results of the simplified manual method. The structure is designed according to ČSN EN.

Design of concrete structure using FRP reinforcement
Mrkvová, Kateřina ; Čairović, Dorde (referee) ; Kostiha, Vojtěch (advisor)
The aim of the bachelor thesis is to carry out a structural design and design of reinforcement of a slab structure in two different variants. In the first one, typical reinforcing steel is used, the second variant is an alternative with composite FRP rebar by the top surface of the slab. Internal forces in the locally supported slab are analysed by SCIA Engineer software and the accuracy of the calculation is verified by equivalent frame method. The thesis includes structural design as well as drawings of reinforcement.

Design of reinforced concrete floor structure
Velič, Marek ; Čairović, Dorde (referee) ; Kostiha, Vojtěch (advisor)
The bachelor thesis focuses on two construction designs on the 3rd floor. The first design is made of pre-stressed panels of SPIROLL type. The second design consists of a reinforced concrete continuous slab design with two bays, a beam, and a column. The internal forces for the design were obtained using SCIA Engineer. These internal forces were checked by hand calculation using the method of three-moment equations. Drawings for the above structures are included in the thesis. The design and assessment of the structures have been carried out as per the applicable standards.

Design of the precast load-bearing structure of the production hall
Knespl, Vojtěch ; Čairović, Dorde (referee) ; Girgle, František (advisor)
The bachelor´s thesis is focused on the design and static calculation of selected elements of the prefabricated load-bearing structure of production hall, the development of basic drawings of the project documentation of the building and drawings of the shape and reinforcement of the solved elements in the details of the implementation documentation. Specifically, it is a T-section reinforced concrete saddle truss, rectangular columns, and headers. The thesis includes a text section that contains a description of the object, the structural system, the individual elements, loads, model, and technological construction process. Calculations were performed using Scia Engineer 21.1, IDEA StatiCa and Microsoft Excel programs.

Design of selected load-bearing elements of reinforced concrete structure
Strmeň, David ; Čairovič, Dorde (referee) ; Kostiha, Vojtěch (advisor)
The aim of the bachelor thesis is to design and assess the reinforced concrete structure of a two-storey car park for ultimate limit state and serviceability limit state. The thesis includes the design of a locally supported slab over the 1st floor, including the design of columns. The analysis of the internal forces on the slab is carried out using SCIA Engineer software and verified by manual calculation using the alternate frame method. Drawing documentation of the proposed elements is an integral part of the work.

Design of a load-bearing reinforced concrete structure of a family house
Bartoška, Ondřej ; Čairović, Dorde (referee) ; Zlámal, Martin (advisor)
Diploma thesis is focused on the construction of a two-storey, partly basement, family reinforced concrete house. The ARCHICAD 22 program was used to design this object, the SCIA 21.0 program was used for the model and the subsequent calculation of internal forces. In addition to the static calculation, the work includes reinforcement drawings and drawings of the shape of selected monolithic parts made in AutoCAD 2021. Reinforced concrete elements are assessed in accordance with ČSN EN 1992-1-1.
