Seismic performance of internally confined hollow RC column with corrugated steel tube공학compositecolumnseismiccorrugate합성기둥내진파형
A column test was performed far a new-type column with a quasi static test. An internally confined hollow reinforced concrete column with a corrugated steel tube (ICH RC-CT column) was tested to evaluate its seismic performance. And also, a general solid RC column was tested fur the comparison. The test was performed as planned drift levels. The lateral displacements and the lateral loads of column specimens were measured during tests. From the test results, the ICH RC-CT column showed smaller energy absorbing capacity than a solid RC column but showed the almost equal energy ductility and equivalent viscous damping ratio to those of the solid RC column.
파형강관으로 내부 구속된 중공 철근콘크리트 기둥(파형강관 내부 구속 중공 RC 기둥, ICH RC-CT column ; Internally Confined Hollow RC column with a Corrugated Steel Tube)의 내진 성능 평가 실험을 수행하였다. 준정적 실험을 통하여 ICH RC-CT 기둥과 일반 중실 RC 기둥의 내진 성능을 비교 평가하였다. 각각의 기둥 시험체에 대해 하중과 변위의 관계를 측정하였으며, 이를 바탕으로 연성도, 소산에너지, 등가 감쇠비, 손상 지수가 계산되었다. 실험 결과 ICH RC-CT 기둥은 중실 RC 기둥에 비해 작은 에너지 소산능력을 보여주었으나, 에너지 연성도와 등가 점성 감쇠비 측면에서는 거의 대등한 성능을 보여주었다.
