摘　　要：本文介绍了应用具有运动极限的序列线性规划方法对钢筋混凝土框架桥进行截面优化设计的方法.文中着重研究了优化设计变量的选择,各种构件的钢筋和混凝土应力约束方程的建立,以及结构近似重分析的方法,还提出了减少计算机时,提高计算精度和保证收敛的措施,获得了对钢筋混凝土框架桥进行整体优化的一个有效方法.In this paper,the move limit sequential Linear programmingmethod is employed in the optimal design of reinforcedconcrete frame bridge.Emphases are laid on the selection ofvariables,the establishment of stress constraints,and themethod for approximate structure reanalysis.Techniques ofreducing computation,incrasing accuracy and quaranteeingalgorithm convergence are also proposed.In this way,aneffective method for optimal design of reinforced concreteframe bridge is obtained.
