CONCRETE AND MASONRY ELEMENTS REINFORCED WITH NEWLY DEVELOPED FRP REINFORCEMENT

A new reinforcement based on glass or carbon fibre reinforced polymers in frame a Czech ministry of industry and trade research task was developed. A set of experiments was made for reinforcing concrete structures with this FRP internal reinforcement. The developed reinforcement was used for reinforcing several concrete elements. These elements were exposed to different types of loading. Their behaviour was monitored to verify the functionality of new reinforcement. Based on this results it is possible to determine required properties of reinforcement used for every type of reinforcing (longitudinal or shear reinforcement). This reinforcement was also used for additional strengthening of masonry vaults stressed with static and dynamic loads. Obtained results are compared with theoretical results of nonlinear numerical analysis of constructions.
