Research on the Effect of Injury Beams Strengthened with Carbon Fiber Reinforced Polymer (CFRP) of the Unloading Degree

Abstract:

The static load test is done on 5 concrete beams. One beam is loaded to the destruction as a contrast specimen, and the other 4 are loaded to the predetermined damage load (80kN), then unloaded to the different load level separately, keeping the load invariable, and tested the improvement in flexing resistance after structural strengthening by CFRP.The research indicates: The ultimate capabilities of the reinforced concrete beam specimens reinforced by carbon fiber sheets can increase 20.93%~39.80% compared with the specimen without CFRP.
