초록

비정형 초고층 구조물은 골조 직교성이 해제되고, 형상이 복잡해 기존 설계방식보다 많은 문제점이 발생된다. 비정형성으로 인한 문제점은 설계안을 지속적으로 변경시켜 프로젝트의 효율성을 저하시킨다. 또한 해외프로젝트의 경우 해당업체 간 혹은 해당국가 간 의견차로 국내보다 더욱 많은 변경상황이 발생되고 있다. 따라서 지속적인 변경상황에 전산플랫폼을 사용할 경우 효율적으로 설계변경업무에 대처할 수 있다. 파라메트릭 기반의 전산플랫폼인 StrAuto를 이용할 경우 최적의 구조설계대안을 신속히 선정할 수 있다. 특히 StrAuto는 비선형 내진성능평가를 위한 해석 툴 간의 신속한 모델링 연동도 효율적으로 가능하다. 그래서 본 연구에서는 지진하중 변경에 따른 전산플랫폼을 이용한 내진성능평가 프로세스를 현재 구조설계가 진행 중인 몽골지역 최고층 빌딩 프로젝트에 적용하고 검증하려 한다.

Complex-shaped tall building causes many structural challenges due to its structural characteristics regarding inclined members and complexed shape. This paper is aimed at development of design process using computational-platform which is effective design tool for responding frequent design changes, particularly as to overseas projects. StrAuto, a parametric structural modeling and optimizing system, provides the optimized alternatives according to design intent and realize a swift process converting a series of structural information necessary to nonlinear analytical models. The application of the process was to a 45-story hotel building in Ulanbator, Mongolia adopting shear wall and special moment frame with outrigger systems. To investigate the safety of lateral force resisting system against maximum considered earthquake(MCE), nonlinear response history analysis was conducted using StrAuto.
