剪力墙最优刚度及其计算机实现

系统地提出了高层框架－剪力墙结构中的剪力墙最优刚度的概念，解决长期以来困绕着高层框架－剪力墙结构设计中剪力墙数量合理确定的困难，提供一种确定剪力墙数量的科学方法。在分析剪力墙赐度与地震作用相互关系的基础上，建立确定了剪力墙最优刚度的数学模型。同时，考虑剪力墙剪切变形，框架住的轴向变形，剪力墙基础的转动，以及剪力墙刚度沿结构高度变化对剪力墙最优刚度的影响。

Optimal Stiffness of Shear Wall and Its Implementation on Computer

With the purpose of conquering the difficulty in reasonably determining the amount of shear walls used for designing a tall frame shear wall structure,the author formulates a concept of optimal stiffness of shear wall in a tall frame shear wall structure;and offers a scientific method for determining the amount of shear walls.An analysis is made on the relation between stiffness of shear wall and seismic excitation as the first step.Based on which,a mathematical model is constructed for the optimal stiffness of shear wall,taking into account of the effects of such factors influencing optimal stiffness as shearing deformation of shear wall,axial deformation of framed column,rotation of the base of shear wall and change of stiffness of shear wall along the height of structure.In computer aided design,such new technologies as dynamic data structure,mode of drawing,mode charting,and redistribution of memory stacks are adopted for running CAD system.An engineering example given finally accounts for the fact that the present work can be applied to the stage of scheme and construction drawing design.
