摘要
本文以内力为设计变量，构造了多工况作用下空间桁架结构拓扑优化的凸二次规划模型，利用其Ｋ－Ｔ条件形成了关于内力、松弛变量和Ｋ－Ｔ乘子的线性互补问题，用修正单纯形方法求解。
In this paper , the member forces are considered as design variables, andconvex quadratic programming model of topology optimization for space truss structure isgiven under mutiple loading conditions. The linear interdependent problem for memberforces and K-T multipliers is formed by making use of its K-T condition)and can be solvedby the modified simplex method.
