Abstract

Despite the increasing incidence of earthquakes in recent years, many of the existing buildings don't have appropriate seismic performance due to the deterioration or structural characteristics. In particular, a piloti-type RC shear wall structure, which is one of the building types in Korea, is highly vulnerable to earthquakes due to a great lack of shear function that can resist lateral force caused by the earthquake since the first floor is mostly soft story, and it is classified as weak story. In this regard, a study on the damage state criterion for the piloti-type RC shear wall structures was carried out. The capacity spectrum was calculated through the structural analysis by selecting typical type of buildings of shear wall systems, and damage state criterion was defined based on the shape of the capacity spectrum.

최근 증가한 지진의 발생빈도에 비해 현존하는 건물 중 내진설계가 되지 않았거나 노후화, 구조특성 등으로 적절한 내진성능을 보유하지 않은 건물은 매우 많다. 특히 우리나라 건물 유형 중 하나인 필로티형 콘크리트 전단벽 구조물은 대부분 1층이 연층(soft story) 및 약층(weak story)으로 분류되기 때문에 지진에 의한 횡력에 저항할 수 있는 전단기능이 크게 결여되어 지진에 매우 취약하다. 본 연구에서는 필로티형 콘크리트 전단벽 구조물의 손상도 기준에 관한 연구를 수행하였다. 전단벽 시스템의 대표 유형 건물을 선정하여 구조해석을 통해 능력스펙트럼을 산출하였으며 능력스펙트럼의 형태를 기준으로 손상도 기준을 정의하였다.
