Abstract

In this paper, a method on deducing the capacity spectrum based on nonlinear earthquake response analysis will be introduced. Damage assessment of general building draws the capacity spectrum through the Push-over analysis and the intersection point of capacity spectrum and demand spectrum is seen as performance point. Push-over analysis is the way to perform static analysis by using the equivalent static load changed from the effect of earthquake and predict the behavior of structures by earthquake. But, this method can not be taken into account in the effects of higher mode and the dynamic characteristic. Therefore, in order to calculate the capacity spectrum under dynamic properties of building. A capacity spectrum from going ahead with the nonlinear earthquake response analysis is suggested.

본 논문에서는 질점계 비선형 지진응답해석을 통한 역량스펙트럼 도출방법을 소개한다. 일반적인 건축물의 손상도 평가는 비선형 등가정적해석(Push-over Analysis)을 통하여 건축물의 역량스펙트럼을 도출하고, 역량스펙트럼과 요구스펙트럼의 교차점을 성능점으로 평가하고 있다. 등가정적해석은 지진의 영향을 등가의 정적하중으로 환산한 후 이를 이용하여 정적해석을 수행함으로써 구조물의 지진에 의한 거동을 예측하는 방법이다. 이 방법은 고차모드 및 층별 동특성의 영향을 고려할 수 없다. 따라서 건축물의 동특성이 반영된 역량스펙트럼을 산출하기 위하여 질점계 비선형 지진응답해석을 진행하여 건축물의 역량 스펙트럼을 제안하고자 한다.
