Development of Automated Optimum Design Program Considering the Design Details

세부설계사항을 고려한 자동최적설계 프로그램 개발

The primary objective of this paper is to develop optimal algorithms of reinforced concrete frame structural systems by the limit state design(CP 1110) and to look into the possibility of detailed design of these structural systems. The structural formulation is derived on the finite element method. The objective of optimization of a reinforced structure for a specified geometry is mainly to determine the optimum cross-sectional dimensions of concrete and the area of the various sizes of the reinforcement required for each member. In addition to the detail s such as the amount of web reinforcement, cutoff points of longitudinal reinforcedments etc. are also considered as design variables. In this study, the method of "Generalized Reduced Gradient, Rounding and with Neighborhood search" and "the Sequential Linear Programming" are employed as an analytical method of nonlinear optimization.

본 연구는 철근 콘크리트 구조물의 새로운 자동화 최적설계 알고리즘을 제시하였다. 기존의 주철근과 콘크리트 단면사이즈 등의 국한된 최적설계 범위를 벗어나 철근의 부착길이, 매입길이, 콘크리트 커버두께 등 세부설계사항까지 모두 고려한 실무에 적합한 효용성 높은 설계알고리즘을 제시함으로써 앞으로 실무분야에 많은 기여를 할 수 있다고 보여 진다.
