Abstract

The purpose of this study is to investigate the seismic performance of both exterior precast concrete cladding panels and their connections on steel frame, when these cladding systems are considered as the structural components. The degrees of their participation of lateral stiffness to the main building are evaluated in terms of different heights of the cladding panels. Considering the cladding system as an integrated building provides additional lateral stiffness, as well as a mechanism for energy dissipation and this system can be used as one of an advanced passive seismic control system. Hysteresis behaviors of connectors are modeled and integrated into a nonlinear finite element analysis program, ABAQUS. The results show that connections play the most important role in structural cladding system and they improve seismic performance of overall building response.

본 연구는 일반 철골구조물에서 사용되는 구조용 프리캐스트 콘크리트 외부벽판과 연결부재로 인하여 건물 전체의 내진성능을 조사하였고, 벽판의 높이 변화에 따른 건물 전체의 횡방향 강성 변화량을 파악하였다. 외부벽판과 연결부재를 구조 부재로 간주할 경우 수동형 제진장치와 같이 지진에너지를 소산할 뿐 아니라 추가로 전체 건물의 횡방향 강성을 제공하는 것을 확인하였다. 이력거동 성능을 가진 연결부재를 비선형 유한요소해석 프로그램인 ABAQUS를 이용하여 조사한 결과, 건물의 내진성능 향상에 연결부재가 가장 중요한 역할을 하는 것으로 확인되었다.
