Abstract

The composited structural member in which two or more materials having different stress-strain relationships (steel & concrete) has increased greatly in recent years. This paper presents the experimental results of flexural capacity of the composited H-Pile subjected to bending moment. Eight composited beams were tested under direct loading condition using the frame tester. Based on the experimental results it is noted that flexural capacity of composited H-Pile increased about 20~30% and ductility ratio significantly increased. Limit state analysis of the specimens was conducted and the result shows that flexural strength by limit state analysis is conservative.

서로 다른 응력-변형률 구성관계를 갖는 2가지 이상의 재료로 구성된 합성구조부재의 사용이 크게 증가하고 있다. 본 연구에서는 철근 및 콘크리트로 보강한 합성 H-Pile의 휨성능을 평가하고자 8개의 실험체를 제작하여 휨실험을 실시하였다. 실험결과 합성H-Pile의 휨성능이 무보강 H-Pile보다 10~30%정도 크게 나타났고, 연성능력은 2배 이상, 에너지소산능력은 3배 이상 증가하였다. 한계상태해석 결과는 실험보다 보수적인 강도예측을 하였다.
