Behavior of newly developed FRP reinforcement in structures under various load schemes
Abstract
An own reinforcement based on glass or carbon fiber reinforced polymers in frame a Czech ministry of industry and trade research task was developed. A set of experiments was made for reinforcing of concrete structures with this FRP internal reinforcement.
The developed reinforcement was used for reinforcing of several concrete elements. These elements were exposed to different types of loading. Their behavior 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 sort of reinforcing (longitudinal or shear reinforcement).
This reinforcement was also used to additionally strengthen the masonry vaults loaded with static and dynamic loads. Obtained results are compared with theoretic results of nonlinear numerical analysis of constructions.
