Use Performance Analysis on the Reinforced Concrete Simply Supported Beam in-Service by CFRP Reinforcing
Based on a secondary load, the formula of calculating the cross-section stress and stiffness of the reinforced concrete simply supported beam by CFRP reinforcing in normal use is derived. Through the comparison and analysis of the load test data before and after the concrete simply supported beam in-service is reinforced, it is showed that CFRP can be coordinated with the concrete in normal use so that the carrying capacity of concrete beam is increased by about 17% to 19%, the stiffness is increased by about 50%, and it is consistent with the formula calculated results.
