Abstract

This study conducted finite element (FE) analysis to investigate the effect of seismic strengthening of H-beam members strengthened with carbon fibre reinforced plastics (CFRP). The buckling loads and the amount of the absorbed hysteretic energy were investigated. As a result, CFRP was effective in reinforcing against buckling load. The buckling load was improved more than 20% with CFRP sheets. Reinforcement was also effective in cyclic loadings, decreasing the reduction in load-bearing capacity to less than 12%. Further, reinforcement increased the amount of the absorbed hysteretic energy, especially in the compression region. Under the assumption that the CFRP would not delaminate, CFRP sheets with larger elastic modulus showed higher reinforcement effects.
