[提要]  为解决高层框剪（筒）结构剪力墙的合理布局问题，提出一种专门用于给定外荷载下受位移约束并使剪力墙重（用）量最小的剪力墙布局优化设计方法——直接迭代搜索法（DISM法），编制了计算机优化程序。算例表明：该法实用简单，收敛平稳，剪力墙布局优化结果令人满意。

This paper presents a shear walls layout optimization method-direct iteration search method( DISM)which can be used specially for the layout optimization of shear walls in the frame-shear walls (or framed tube) structures subjected to displacement constraints under given external loads.  Numerical examples show that the proposed algorithm practical, simple, converges smoothly and gives rational and satisfactory solutions. DISM is an effective method to solve the shear walls rational layout problem.
Keywords: layout optimization; shear wall, frame-shear wall structure
