Study on Shear Resistance and Durability of CFRP Reinforced Concrete Beams

Abstract:

Through carrying capacity test of CFRP strengthened test beam and unstrengthened comparison beam under corrosion of chlorine ion, thispaper analyzes the shear resistance and durability of CFRP repaired and strengthened concrete beam. Crack generation, deflection, electrochemical index and deformation of reinforced concrete beam under service are comparedand analyzed. It is indicated that CFRP can play a favorable screening role and can effectively prevent crack development. There is no shear failure after load is applied. So CFRP can obviously improve the shear bearing capacity and durability of reinforced concrete beam. Besides, different strengthening methods have relatively obvious influence of its durability.
