The structural optimum design with discrete variables under stress and section size constraints is performed using this method.
这种方法能直接求解具有应力约束和几何约束的离散变量结构优化设计问题。

In the optimum design, effects of variety of structure type and structural components on stress are analysed, so that reasonable structure type and component dimensions may be obtained.
在优化设计中，用正交法分析了结构形式和构件变化对应力变化的影响，得出了合理的结构形式和构件尺寸。
