Abstract

In this paper, the previous damage models for structures and their components under seismic repeated loading were reviewed systematically. A failure criterion for steel members under severe cyclic excitations as in strong earthquakes was described. A new approach to seismic damage assessment for steel members was proposed. This method was based on a series of the experimental and numerical investigations for steel members under very low cyclic loading. In this study, very low cyclic loading means repetitive loading, 5 to 20 loading cycles, within the large plastic range. The proposed damage assessment method was focused on the local strain history at the cross-section of the most severe concentration of deformation.

본 논문에서는 정량적인 지진 손상모델의 유도를 위해 먼저 지진 반복하중하에서 구조물 및 그들 요소에 대한 기존의 손상 모델들을 체계적으로 정리한 후 문제점을 평가하였다. 또한, 강한 지진과 같은 심한 반복가력을 받는 강구조 부재에 대한 파괴기준을 묘사하였으며, 강부재에 대한 새로운 지진 손상도 평가방법을 제안하였다. 이 손상모델은 극저 사이클 하중하에서 강부재에 대한 일련의 실험과 수치해석 연구로부터 얻어진 것이다. 본 연구에서 극저 사이클 하중은 큰 소성변형 영역안에서 5~20 사이클의 반복하중을 의미한다. 제안된 내진 손상평가 방법은 변형이 가장 심하게 집중된 단면에 있어서 국소 변형율의 이력에 초점을 맞추어 유도되었다.
