摘　　要：以满应力设计思想为基础，提出了离散变量结构优化设计的拟满应力设计方法。算例结果表明，该方法能直接计算具有应力约束和截面尺寸约束的离散变量结构优化问题，也能处理同时具有稳定约束和位移约束的多工况、多约束、多变量的离散变量结构优化设计问题。Based upon an idea on full stress design, a quasi full stress design method is presented for structural optimum design with discrete variables in the paper. The results of examples show that this method can be used directly to work out the structural optimum design with discrete varirables, which involve the stress constraints and cross section size constraints. The method can be also dealt with the structural discrete optimization with multi variables, multi loading and multi constraints.
