Aging and deterioration of existing steel structures necessitates the development of simple and efficient rehabilitation techniques. Strengthening with bonded Carbon Fiber Reinforced Plastic plate has been rarely applied to steel structures, although it has often been applied to concrete structures. To enhance the usage life of existing steel buildings, a strengthening method with bonding Continuous fiber reinforced plastic (FRP) plates has been developed by authors. Bonding properties such as strength and stiffness are required to predict the fiexural rigidity and yield moment as well as the stresses induced in FRP plates of rehabilitated members. This paper reports the results of elastic-plastic analyses conducted on shear bond test specimen between FRP and steel. These results show bonding properties of adhesive and load carrying capacity of shear bond test specimen. An analytical method is also proposed that can predict bonding mechanism and strength of FRP plates.
