Abstract

A nonlinear column model of an internally confined hollow (ICH) reinforced concrete (RC) column was suggested and a parametric study was performed. The suggested column model considered the confining effect and the material nonlinearity of concrete. To verify the suggested column model, its analysis results were compared with the test results from previous researchers and a quasi static test performed in this study. They showed that the suggested column model was reasonable and had acceptable accuracy. The results from parametric studies showed that the thickness of the internal tube, concrete strength, and the hollow ratio of the ICH RC column affected its behavior.

내부 구속 중공 철근콘크리트(ICH RC, internally confined hollow reinforced concrete) 기둥의 비선형해석 모델을 제시하고 매개변수 연구를 수행하였다. 제안된 기둥 해석 모델은 콘크리트의 구속효과와 재료비선형을 고려하였으며, 해석 결과와 이 연구에서 수행된 ICH RC 기둥 실험 결과 및 선행 연구자들의 실험 결과를 비교하여, 해석 모델을 검증하였다. 검증 결과 제안된 기둥 해석 모델은 만족할 만한 결과를 보여주었으며, 매개변수 연구를 통하여 내부강관의 두께, 콘크리트의 강도와 중공비에 따른 ICH RC 기둥의 거동 특성을 나타내었다.
