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.

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.

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.

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.

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 elements with FRP reinforcement
Mrkvová, Kateřina ; Lagiň, Juraj (referee) ; Kostiha, Vojtěch (advisor)
This diploma thesis focuses on deflection of reinforced concrete structures with FRP rebar. The thesis presents and compares various approaches on deflection of reinforced concrete structures with steel and FRP rebar based on national and international standards and existing research. The aim of the thesis is to point out differences among the various approaches and present the most suitable one for the particular case. Based on theoretical and experimental results, the goal is to modify one of the existing approaches or present a new method which would correspond with real deflection behaviour of FRP reinforced concrete beam. Simply supported beam with three-point bending was selected as a reference element. Analytical study and numerical analyses by ATENA software are performed. Results of analytical and numerical study are compared to experimental results.

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.
