Abstract

The study purposed to investigate the optimal location of core and offset outrigger system considering floor diaphragm. To accomplish this aim, a structure design of 70 stories building was performed by using MIDAS-Gen. And the leading factors of the analysis research were the slab stiffness, the stiffness of shear wall and the outrigger position in plan. Based on the analysis results, we analyzed and studied the influences of the shear wall stiffness and the slab stiffness on optimal location of core and offset outrigger considering floor diaphragm. The results of the analysis study indicated whether the slab stiffness, the stiffness of shear wall and the outrigger position in plan had an any impact on optimal location in outrigger system of tall building. Also the paper results can give help in getting the structural engineering materials for looking for the optimal position of outrigger system in the high-rise building.

본 논문은 바닥 격막을 고려한 코어 및 오프셋 아웃리거 구조의 최적위치를 파악하기 위하여 70층 규모의 초고층 아웃리거 건물을 대상으로 MIDAS-Gen을 이용하여 구조설계를 실시하였다. 그리고 본 해석연구의 주요 변수는 슬래브의 강성, 전단벽의 강성, 아웃리거의 평면상 위치이다. 또한 본 해석결과에 근거하여 슬래브의 강성과 전단벽의 강성이 바닥 격막을 고려한 코어 및 오프셋 아웃리거 구조의 최적 위치에 미치는 영향을 분석하였다. 본 해석연구의 결과에서는 슬래브의 강성, 전단벽의 강성, 아웃리거의 평면상 위치가 초고층 아웃리거 구조시스템의 최적위치에 어떤 영향을 주는 지를 분석하여 나타났다. 그리고 본 논문의 결과는 초고층 아웃리거 구조시스템의 최적위치를 조사하는데 필요한 구조공학자료를 얻는데 도움이 된다고 사료된다.
