To enhance the usage life of existing building, a tensile force strengthening method with bonding
carbon fiber reinforced plastic (CFRP) plate has been developed by the authors.
To enhance the strength and deformation of steel structure member, a rehabilitation technique of
compressive force strengthening as well as tensile force strengthening is nequired.
This paper reports the result of the loading tests on a full scaled angle steel brace before and after
rehabilitation using bonding CFRP plates.
These results show enhanced compressive force carrying capacity and deformation capacity of brace
by bonding CFRP plates and a proposed rehabilitation is practical and effective for a bracing steel
structure.
