Abstract

Fragility curves show the probability of a system reaching a limit state as a function of some measure of seismic intensity. To obtain fragility curves of six and twelve story staggered wall structures with middle corridor, incremental dynamic analyses were carried out using twenty two pairs of earthquake records, and their failure probabilities for various intensity of seismic load were investigated. The performances of staggered wall structures with added columns along the central corridor and the structures with their first story walls replaced by columns were compared with those of the regular staggered wall structures. Based on the analysis results it was concluded that staggered wall structures with central columns have the largest safety margin for the same level of seismic load.

지진취약도 곡선은 구조물의 피해를 지반가속도에 따른 확률로 나타낸 것으로, 이를 이용하여 구조물의 지진에 대한 손상확률을 추정할 수 있다. 본 연구에서는 6층, 12층 중복도형 격간벽 구조 시스템에 대한 취약도 곡선을 산출하기 위해 22쌍의 지반가속도를 이용하여 증분동적해석(Incremental dynamic analysis)을 수행하고, 다양한 지진강도에 대한 파괴확률을 구하였다. 정형의 격간벽 구조의 해석결과와 1층의 격간벽을 기둥으로 대체한 구조물, 중앙 복도에 기둥이 추가된 구조물의 해석결과를 비교하였다. 취약도 해석결과에 따르면 동일한 수준의 지진하중에 대하여 중앙 복도에 기둥을 추가한 모델이 가장 높은 내진 안전성을 갖는 것으로 나타났다.
