An Experimental Study for the Failure Mode and the Ductility of a High Pier with a Hollow Section using a High Strength Cocnrete and Steel

고성능 중공단면 교각의 파괴모드 및 연성에 관한 실험적 연구

Six RC pier were tested under a constant axial load and a cyclically reversed horizontal load to investigate the performance of RC piers used in the high strength concrete and the high strength rebar. It is designed with a hollow section according to the Korean Bridge Design Standard. The variables of the test were concrete strength, rebar strength, a ratio of lap splice and a ratio of transvere rebar. The test results show that the performance of a RC Pier; failure mode, crack pattern, maximum load and ductility.
