摘要: Advanced fibre reinforced polymer (FRP) composites have been increasingly used over the last two decades for strengthening, upgrading, and restoring degraded civil engineering infrastructure. Substantial experimental investigations conducted in recent years to understand compressive behaviour of FRP-confined concrete columns. A considerable number confinement models predict FRP strengthened columns developed from results these investigations. The purpose this paper is present a comprehensive review theoretical circular non-circular confined with reinforcement. The reviews previous test on reinforcement under concentric eccentric loading conditions highlights mechanics also existing both sections. This demonstrates that performance effectiveness extensively investigated proven effective enhancing structural ductility strength enhancement depend layers, strength, corner radius columns, intensity load eccentricity eccentrically loaded impact directions future research are presented. Potential researchers will gain insight into studies directions.
