Abstract

An efficient design concept for earthquake loads, which is called performance based design, has been standard design in USA, Europe and Japan since those countries experienced severe earthquake damage at end of 90's. For general design, struttie model well predicts the strength of the disturbed region, however, it does not provide ductility information at the failure. Therefore, simple tools which are able to predict both the strength and the ductility of RC structures are in demand. 2D lattice model is introduced in this study as an analysis tool for the RC structures subject to earthquake. Experimental correlation studies indicate the 2D lattice model quite well predict the strength as well as the ductility of RC structures.

미국, 유럽 그리고 일본에서는 90년대 말에 큰 지진을 경험하면서부터 지진에 대한 성능 설계 개념이 설계 기준에 포함되기 시작하였다. 일반적으로 스트럿-타이 모델은 D-영역에서 비교적 강도를 잘 예측하지만 파괴 때 연성정보를 제공하진 않는다. 그러므로 RC 구조물의 강도와 연성을 예측할 수 있는 간단한 해석 도구가 필요하다. 이 연구에서 RC 구조물의 지진에 대한 거동을 해석할 수 있는 도구인 2차원 래티스 모델을 제안한다. 2차원 래티스 모델은 실험을 통한 상관관계 연구에서 RC 구조물의 강도뿐만 아니라 연성도 예측하는 것으로 나타났다.
