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.

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.

Experimental and numerical analysis of reinforced concrete elements
Niedoba, Jakub ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This master‘s thesis deals with the behaviour of strengthened reinforced concrete beams. The aim was to evaluate different types of strengthening in comparison not only with each other, but also with the reference beam. Three reinforced concrete beams were fabricated for the purpose of the thesis. The first served as a reference beam, the second was strengthened with carbon lamella glued to the lower edge of the reinforced concrete beam, and the last one was strengthened with unbonded post-tensioning system. Subsequently, they were all loaded by a four-point bending. An evaluation was then carried out which shows that the two strengthened reinforced concreate beams resist the load much better than the reference beam. In the conclusion, different utilization possibilities of both methods are listed, as well as the disadvantages that must be taken into account when designing.

Use of composite materials for the design of concrete structures
Vašátko, David ; Januš, Ondřej (referee) ; Girgle, František (advisor)
Composite reinforcement tends to be perspective material for construction reinforcing. Its application is suitable especially for areas with high level of environmental stress, or environment loaded with physical phenomenon. This thesis is focused on inner FRP reinforcement. Theoretical part deals with mode of production, types of used materials, behavior depending on stress type and different approaches towards designing for short-term or long-term load capacity of composite reinforcement. Practical part includes assessment of precast element, dealing with requirement of non-magnetic reinforcement. Assessment is designed with two alternatives, each of them differing in type of main load-bearing reinforcement. First one works with stainless steel reinforcement, the second one with GFRP one.

Experimental study of reinforcement in light-weight concrete components
Lisztwan, Dominik ; Kocáb, Dalibor (referee) ; Vymazal, Tomáš (advisor)
This bachelor thesis describes the experimental comparison of behaviour of reinforced lightweight concrete panels. Panels are reinforced with traditional steel grid and basalt composite reinforcement. The comparison of results is based on set of data from static load tests. The results of load test are also compared to the results made with nonlinear numerical analysis by finite element method and also calculation by hand. A part of this thesis includes determination of physical and mechanical properties of used concrete.

Reinforced concrete load-bearing construction
Tmej, Patrik ; Buřič, Pavel (referee) ; Šulák, Pavel (advisor)
The aim of the thesis is the strengthening and resistance of concrete construction. At the beginning is described composite reinforcement and their specific properties. The thesis specifically follows behavior concrete vault and the effects of load. Resistance vault is calculated by S&T model – strut and tie. Finally, the thesis contain strengthening construction by composite reinforcement. Strengthening is considered by two ways - strengthening by cohesive reinforcement and strengthening by incoherent reinforcement (wrapping).

Structural laminated wood reinforced with composite materials
Kovács, Pavel ; Horák, David (referee) ; Žítt, Petr (advisor)
This master’s thesis describes an experimental program investigating the strengthening of beams of glued laminated timber with composite reinforcement. The work compares the behavior of beams reinforced with composite reinforcement with unreinforced beam and with solid timber beam. The work also deals with identifying and evaluating the physic-mechanical properties of materials.
