The authors have developed a tensile force strengthening method using bonded carbon fiber reinforced plastic (CFRP) plate to enhance the life of existing buildings. A rehabilitation technique for compressive force strengthening as well as tensile force strengthening is required to enhance the strength and deformation of steel structural members. This paper reports the results of compression loading analysis conducted on an hollow section steel member before and after rehabilitation using CFRP plates. These results show enhanced axial force carrying capacity and plastic deformation capacity of the member by bonding CFRP plate and the proposed rehabilitation is effective for moderately slender compression member of steel structure.
