In this study, the seismic response is investigated by using a relatively low-rise building under torsion-prone conditions and three seismic loads with change of the location of the seismic isolation system. LRB (Lead Rubber Bearing) was used for the seismic isolator applied to the analytical model. Fixed model without seismic isolation system was set as a basic model and LB models using seismic isolation system were compared. The maximum story drift ratio and the maximum torsional angle were evaluated by using the position of the seismic layer as a variable. It was confirmed that the isolation device is effective for torsional control of planar irregular structures. Also, it was shown that the applicability of the midstory seismic isolation system. Numerical analyses results presented that an isolator installed in the lower layer provided good control performance for the maximum story drift ratio and the maximum torsional angle simultaneously.
Construction techniques and materials are developing and structures are designed to be irregular shaped, and therefore more detailed structural analysis is required. The purpose of this study is to analyze the cause of accidents related to falsework systems during construction and discuss prevention methods in order to prevent accidents relate to prefabricated shoring system during construction. In this paper structural analysis was conducted to study the influence of slab irregularity on system supports and analysis to investigate the participation of the bracing in the system support.
최근 컴퓨터 기술의 발달로 인해 복잡한 형태를 가지는 기념비적인 건축물이 설계, 시공됨에 따라 비정형건축에 관한 사회적인 관심이 해외뿐만 아니라 국내에서도 증가하고 있다. 하지만 비정형 구조시스템의 구현하기 위한 기술 및 연구에 대한 사례가 부족하여 많은 어려움이 있다. 이러한 문제를 해결하기 위해 본 연구에서는 3D모델링 프로그램과 최적설계를 수행하는 프로그램간의 인터페이스 모듈에 대한 연구를 수행하였다. 3D 모델링 프로그램에서 자동 메쉬를 생성하고, 모델링에 대한 정보를 바로 추출하여 최적화를 수행하였다. 결과적으로 개발된 인터페이스 모듈의 검증을 위해 예제 모델을 선정하여 형상최적화을 수행하였다.
