NUMERICAL SIMULATION OF FRACTURE BEHAVIORS ON THE FRPSTRENGTHEND REINFORCED CONCRETE STRUCTURES

摘要

The technique of bonding Fiber Reinforced Polymer (FRP) composites to the tension face of Reinforced Concrete (RC) beams has become very popular for strengthening purposes. In this paper, RFPA (Realistic Failure Process Analysis) is used to simulate the fracture behaviors and load carrying capacity of FRP-strengthened RC beams, which mainly focus on the effects of thickness of FRP on fracture behaviors of strengthened RC beams and the load carrying capacity. The simulation results agree well with the experiment observations. The simulation results indicate that RFPA method provide a new method and approach to simulate the failure process and mechanical behavior of reinforced concrete structure.
