FEM Analysis of Rehabilitated Steel Member using CFRP Plates Part 1 Treatment of Anisotropy and Failure Rule

摘要

To enhance the usage life of existing building a tensile force strengthening method with bondingcarbon fiber reinforced plastic (CERP) plate has been developed by authors. To enhance the strengthand deformation capacity of steel structure member, it is required a rehabilitation technique forcompressive 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 typecarbon fiber). This paper reports the result of loading tests and F.E.M analyses on a full scaled anglesteel brace before and after rehabilitation using bonding CFRP plates. These results show enhancedcompressive force carrying capacity and deformation capacity of brace by bonding CFRP plates couldbe predicted roughly through F.E.M. analysis results.
