| 摘 要： | 本文给出了刚架结构优化设计的一种新方法,依据结构可分解的特点,将整体优化设计分解为两个水平上的优化设计,对一个给定的结构,在 botton-level 上,每一个单元是一个子问题,优化设计其横截面尺寸;在 top-level上优化设计其整体几何,算例表明,这种算法是相当有效的.

| Abstract: | A new method for optimum design of rigid frame structure is presented.The method is based on a hierarchical decomposition of the structure.The bottom-level consists of many subproblems,cach dealing with the cross-sectional sizing of a given frame-element based on Two-direction Shape Multiplier.The top-level consists of one subproblem which is formulated for configuration design of the frame structure.Example is presented to demonstrate the effectiveness of the method. |
