Abstract

To enhance the usage life of existing building a tensile force strengthening method with bonding carbon fiber reinforced plastic (CERP) plate has been developed by authors. To enhance the strength and deformation capacity of steel structure member, it is required a rehabilitation technique for compressive force strengthening as well as tensile force strengthening. There are two types of CFRP plate, TL (high-tenacity type carbon fiber) and ML (middle modulus type carbon fiber). This paper reports the result of loading tests and F.E.M analyses on a full scaled angle steel brace before and after rehabilitation using bonding CFRP pates. These results show enhanced compressive force carrying capacity and deformation capacity of brace by bonding CFRP plates and ML (middle modulus type) CFRP plates is more effective for enhancing compressive strength than TL (high tenacity type) CFRP plate.
