对偶规划法在钢管混凝土拱桥结构优化设计中的应用

APPLICATION OF THE DUAL THEORY TO THE CFST STRUCTURE'S OPTIMIZATION DESIGN

摘要: 本文采用变换方法,将原问题转换为对偶问题,对钢管混凝土拱桥结构进行优化设计。算例表明,本文所述方法简便、实用,尤其适用于大型复杂结构的多变量优化设计。

Abstract: This paper addresses the optimal design of arch bridge made from concrete filled steel tubes(CFST). The problem is converted into a dual one with the aid of transformation. The results show that the present method is simple, reliable and can be applied to the multi-variable optimization design of large structures.
