摘要: This paper presented a non-linear finite element (FE) analysis to investigate the potential of unbonded carbon fiber-reinforced polymers (CFRP) strengthening in improving axial compression performance steel members. The FE model was firstly developed and validated against experimental works. Four parameters considered parametric study were number CFRP layers, length, slenderness ratio, elastic modulus CFRP. It confirmed that method is effective at enhancing load-carrying capacity as well delaying overall buckling strength increase highly affected by first three parameters. In addition, an equivalent ratio can be used for design.
