파라메트릭 기법을 이용한 비정형 초고층 건물의 최적 구조시스템 선정

This study suggests the methodology for selection of optimal complex-shaped super-tall building structural systems using parametric design technique. The presented methodology include parametric modeler related structural analysis software, so that, geometry models generated using parametric technique can be analyzed and evaluated automatically in a integrated system. In extracting optimal alternative, target conditions can be considered in parametric modeler, so that, modeling and optimization can be carried out in a one integrated system and the optimal alternative according to the change of target conditions can be extracted dynamically. The applicability of the presented parametric methodology was checked by applying this technique to the complex-shaped super-tall buildings. Three structural systems, such as diagrid, braced tube and outrigger system were chosen as basic structural system and here, twist angle and section thickness of main structural members was parameterized. The target conditions was set as minimum weight satisfying lateral drift criteria. As the application results, the optimal alternative satisfying target conditions can be extracted automatically, and this showed the applicability of the proposed methodology.
