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。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.
