FEM Analysis of Rehabilitated Steel Member using CFRP Plates Part 2 Stiffening Effect on Subsidiary Beam with Faults

The authors have developed a tensile force strengthening method using bonded carbon fiber reinforced plastic (CFRP) plate to enhance the life of existing building. This paper reports the result of loading tests and F.E.M. analyses on a subsidiary beam before and after rehabilitation using bonding CFRP Plates. These results show the required bonding length to recover the its original flexural stiffness. And rehabilitated effect could be evaluated by presented calculation to take an additional bonding length
