Abstract:
Based on the experiment of 11 models of RC beams with CFRP plates, the regularity of stress and strain of beams with different paste formats, concrete intensity and shear-span ratio were studied, andflexural capacities of beams strengthened with CFRP plates were investigated. The experimental results show that ultimate bearing capacities of specimens vary with different strengthened methods: ultimate bearing capacities of RC beams with CFRP plates end anchorage have been strengthened remarkably; the beams have greater capacity with more anchorage length for those without anchorage; ultimate bearing capacities enhance more prominent for those specimens which have high shear-span ratio and low ratio of reinforcement.
