Abstract |
The present paper represents experimental studies on the performance of concrete filled FRP columns. Eight scale-down specimens were conducted by quasi-static cyclic loading test. FRP thickness, concrete strength, horizontal rebar ratio, and diameter were selected as test parameters. The capacities of ductility for cyclic loading was evaluated and the damping ratio and failure mode from the stiffness reduction of each test specimen were compared.
