Abstract

Seismic design of braced frames that simultaneously considers economic issues and structural performance represents a rather complicated engineering problem, and therefore, a systematic and well-established methodology is needed. This study proposes a multi-objective seismic design method for an inverted V-braced frame with suspended zipper struts that uses the non-dominated sorting genetic algorithm-II(NSGA-II). The structural weight and the maximum inter-story drift ratio as the objective functions are simultaneously minimized to optimize the cost and seismic performance of the structure. To investigate which of strength- and performance-based design criteria for braced frames is the critical design condition, the constraint conditions on the two design methods are simultaneously considered (i.e. the constraint conditions based on the strength and plastic deformation of members). The linear static analysis method and the nonlinear static analysis method are adopted to check the strength- and plastic deformation-based design constraints, respectively. The proposed optimal method are applied to three- and six-story steel frame examples, and the solutions improved for the considered objective functions were found.

본 논문에서는 Nondominated sorting genetic algorithm-II(NSGA-II)를 이용한 Zipper를 가진 역V형 중심가새골조의 다 목적 최적내진설계기법을 제시한다. 부재의 단면성능을 설계변수로 사용하는 제시된 최적화기법은 내진설계를 위해 부재의 강도조건, 구조물의 층간변위조건, 부재의 변형조건 등을 만족시키면서 구조물의 물량과 구조물의 최대 층간변위율을 동시 에 최소화하는 문제로 정식화된다. 구조물의 물량과 최대 층간변위율을 최소화하는 이유는 구조물의 비용과 성능을 각각 최 적화하기 위해서 이다. 선형 정적해석을 통해 구조물의 강도 및 층간변위 제약 조건을 검토하며, 비선형 정적해석을 통해 구 조물의 변형 조건 및 내진성능을 평가한다. 제안된 기법을 검증하기 위해 3층과 6층 Zipper를 가진 역V형 중심가새골조 예 제를 사용한다. 이를 통해 얻은 설계안을 초기 설계안과 비교분석하여 제안된 기법의 적용성을 확인한다.
