Earthquake that occurred within a period of several years may be caused reinforced concrete column fails to maintain its performance. Reinforcement methods improve the quality in resisting earthquake loads are needed. Strengthening with external restraints is expected increase strength concrete. The use synthetic Fiber Reinforced Polymer (FRP) as composite material for restraint on structures o...

The axial compression strength of concrete columns has been proved to be significantly enhanced by external confinement. In this perspective, the use Fiber-Reinforced Polymers (FRPs) extensively studied. practical applications, FRP-confinement is installed on loaded columns, which can already deformed, while theoretical models neglect aspect. This paper concerns a new experimental investigation...
