Abstract

The General conceptual constitution of structural optimization is formulated and the algorithm using the gradient projection method and design sensitivity analysis is discussed. Examples of minimum-weight design for six-story steel plane frame are taken to illustrate the applicability of this algorithm. The advantages of this algorithm such as marginal cost and design sensitivity analysis as well as system analysis are explained.

구조물의 최적설계에 대한 일반적인 개념이 제시되며 Gradient Projection법과 설계민감도 해석을 사용한 최적화 알고리즘이 논의된다. 6층 평면 철골 구조물의 최소무게설계의 예를 통해 이 알고리즘의 적용을 예시한다. 시스템 전체의 비용분석뿐만 아니라 임계 비용 및 설계민감도 해석과 같은 이 알고리즘의 장점에 관하여 설명한다.
