Design of selected details of concrete structures reinforced with composite reinforcement
Vašátko, David ; Lyčka, Lukáš (referee) ; Girgle, František (advisor)
The aim of this master thesis is to explore and describe behavior of slab in punching shear. In total four concrete slabs were experimentally tested; each being reinforced differently. Using real experiments, there was a possibility to observe different behavior of steel and FRP reinforcement, eventually even the effect of adding FRP stirrups on load-bearing capacity. For the purpose of experimental testing design, currently placed formulas used to determine punching shear capacity were adjusted for application on longitudinal and shear FRP reinforcement. Atena software was used to approximate behavior of specimens by performing a nonlinear analysis. After the results of loading tests were obtained, next step was the comparison of design approaches and comparison of behavior of nonlinear model to a real specimen. In practical part, design of locally supported slab with requirement of non-magnetic reinforcement took place.

Concrete structures with FRP reinforcement
Valent, Matej ; Januš, Ondřej (referee) ; Girgle, František (advisor)
The bachelor thesis deals with the usage of FRP reinforcement in concrete structure designs. The designed structure is a sedimentation reservoir that consists of two prefabricated segments. The construction is classified into the XC4 exposure category. The theoretical part of the thesis provides an overview and explains particular types of FRP reinforcement, their properties, and mechanical durability. We describe GFRP reinforcement and its design for bending and shear, consecutively providing different approaches in a plan for a short-term or long-term carrying capacity. The experimental part of the thesis contains two alternatives. The first application involves B500B reinforcement in both prefabricated segments, while the second part, it is using Schöck ComBAR® reinforcement instead. Moreover, both possibilities and their design take into consideration the ultimate limit state. Subsequently, the obtained results are compared. The experimental part of the thesis includes calculations as well as drawings documentation.

Design of concrete structures reinforced with FRP reinforcement
Bártová, Denisa ; Januš, Ondřej (referee) ; Girgle, František (advisor)
The thesis deals with design of a FRP reinforced concrete structure. The structure is a two way floor slab designed in two ways. The first one is typically reinforced concrete; in the second, the upper reinforcement is replaced with a FRP reinforcement. Ultimately, both variations are compared at the end. The floor structure is located in exposure class XD1. The thesis includes a structural design as well as drawings. All calculations were performed in accordance with Eurocode 2 and Fib. Bulletin No. 40.

Application of FRP reinforcement in the design of concrete structures
Kratochvílová, Barbora ; Lagiň, Juraj (referee) ; Girgle, František (advisor)
This bachelor thesis deals with two types of reinforcement FRP reinforcement and generally used steel reinforcement. The first part of this thesis is focused on theoretical knowledge related to FRP reinforcement. There is described its composition, properties, production, durability and its design properties from a theoretical point of view. In the following part, the design and assessment of a specific prefabricated U part is performed. The design and assessment is performed in two variants from FRP reinforcement and steel reinforcement.

Structural assessment of the existing reinforced-concrete frame structure of the production building
Pražan, Jiří ; Krůpa, Pavel (referee) ; Girgle, František (advisor)
The diploma thesis deals with the structural assessment of the existing reinforced concrete frame structure of the production building. The structure under consideration is carried out as a reinforced concrete monolithic frame structure with a discrepancy of 6,15 x 6,15 m (axis). The object has a rectangular plan of 13 x 9 fields. The total dimension is 56 x 81m and is divided into three dilation units on all floors by two inserted 3,65 m wide fields. The building has three above-ground floors and one underground floor. The construction height of the basement is 3,675 m, above ground level 4,0 m. On the west side of the building (axis A) are three reinforced concrete elevator shafts with a dimension of approximately 4,5 x 3,8 m. The envelope and inner partitions are made of bricks full of burned. The work shall include a static assessment of the status quo, a determination of the load capacity and a proposal for appropriate adjustments to ensure static reliability.

Design of selected details of concrete structures with embedded FRP reinforcement
Lagiň, Juraj ; Matušíková, Anna (referee) ; Girgle, František (advisor)
The diploma thesis is devided into two levels. The Primary part of the thesis is the theoretical part, which is part of project „FV10588 – New generation of spatial prefab made from high-firm concrete with increased mechanical resistence and endurance“, realized in cooperation with Faculty of Civil Engineering at VUT university – Institute of concrete and masonry structures. The project deals with frame corners in the form of steel and composite reinforcement which will compared through experiments and various kind of calculate proceedings. The secondary part of thesis focuses on the static-design project of cooling reservoir, placed under the ground, while is stressed by temperature. The reinforcement of the construction is realized in two ways – steel and composite reinforcement with their effectivity compared.

Reinforced concrete structure of residential building
Vilímek, Václav ; Girgle, František (referee) ; Požár, Michal (advisor)
The bachelor thesis deals with the design and assessment of the reinforced concrete ceiling structure of an apartment building. The design of the structure was carried out using SCIA Engineer using the finite element method and subsequently verified by manual calculation. The design of the structures was carried out according to the valid European standards ČSN EN 1992-1-1 and ČSN 73 1201. The result of the work is the design of the reinforced concrete floor slab and staircase. The scope of the work was made in a BIM-compatible design.

Design of the load-bearing RC structure of the kindergarten
Ježek, Jakub ; Požár, Michal (referee) ; Girgle, František (advisor)
This bachelor thesis deals with design and structural analisys of the supporting part of monolithic reinforced concrete structure of kindregarden by using methodology of BIM. In the bachelor thesis was made a calculation of the load, static analysis of the structure and optimal reinforcement design. Based on the static calculation a digital 3D model of reinforcement was created, along with technical drawing and technical report.

Design of the reinforced-concrete structure of the production building
Vavřiníková, Denisa ; Vašátko, David (referee) ; Girgle, František (advisor)
The subject of this bachelor thesis is a proposal and assessment cast-in-place reinforced slab object manufacturing in three options. Frist option is a slab with beams and variable load 5 kN/m2. Second option with enlarged load 20 kN/m2. Floor slab in this geometry isn´t capable to transfer the load that is why third option is calculated. Third option is primary beams and added longitudinal secondary beams. The construction is proposed for ultimate limit state in compliance with ČSN EN 1992-1-1. To calculate the internal forces, three 3D modules were created in software SCIA Engineer. The result of this these are three structurals designes and drawnings.

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.
