초록

본 논문은 고층건물의 지진응답해석에서 탄성 및 탄소성 응답스펙트럼 해석법에 대하여 고찰한 것이다. 선형 구조물의 지진응답 해석에 널리 사용되고 있는 응답스펙트럼법은 여러 연구자들에 의해 서로 다른 모드 조합방법으로 제안되었으며, 이들 조합방법에 따른 차이점을 상세히 검토하였다. 탄소성 지진응답해석에 응답스펙트럼법은 아직 널리 사용되고 있지 못한 실정이다. 본 연구에서는 장주기를 갖는 고층 건물의 탄소성 지진응답해석에 응답스펙트럼을 확장하여 적용하는 방법을 제시한다. 본 논문에서 제안한 탄소성 응답스펙트럼법을 이용하면, 고층건물의 예비 설계에서 시간이력해석 대신으로 보다 간편히 탄소성 응답치를 예측하는 도구로서 활용할 수 있을 것으로 사료된다.

This paper examined various aspects of a linear and a nonlinear response spectrum method in seismic response analysis of multi-story building structures. The response spectrum method that has been widely used in the analysis of linear structures was proposed different mode superposition method by several ivestigators, and the differences between combinations with an elastic modal analysis reviwed closely. It seems, however, that this method is not used to nonlinear seismic analysis. It is the purpose of this paper to propose an alternative method by means of which a nonlinear MDOF structure with long period may be analysed by an extention of response spectrum method. For nonlinear seismic analysis of high-rise building structures using technique proposed in this study, it is intended to serve primarily as a tool in preliminary designs instead of time history analysis.
