CAPACITY ENHANCEMENT OF FRP-STEEL DOUBLE-STRAP JOINTS USING BI-DIRECTIONAL CFRP FABRIC

摘要：

　　Carbon fibre reinforced polymers(CFRPs)have gained popularity and become recognized as a prominent material for engineering applications in the last few decades due to their high strength-toweight ratio,resilience and corrosion resistance.The key concern is the bond between the CFRP and steel elements.The type of CFRP utilized in strengthening systems is dependent on the amount of deterioration to which a structure is subjected.This paper reports the results of an experimental analysis of three sets of specimens,consisting of 45 samples in total to investigate the bond properties between steel and CFRP using a new anchorage configuration.The anchorage system is utilized to delay or counter the effect of debonding of the joints.The results show that the utilization of normal modulus CFRP sheets in conjunction with laminates increases the ultimate strength of the joint by approximately 30%.
