(湖南大学 长沙 410082)[提要] 以剪力墙弯矩为未知数,以框架楼层的剪切刚度为参变数,建立了一组基本方程式。此方程组适用于楼层刚度变化不规则的框架.剪力墙结构分析。基于基本方程组的特性,还提出了分段计算的方法,以便很快求得任一区段内的楼层内力和相对位移。
[关键词] 力法解 框架-剪力墙 高层建筑An approximate analysis of non-uniform shear wall frame structures is presented. It can be used directly to systems with irregular story stiffness.lt can be simplified by neglecting the bending moments farther away than two stories, if the moment of the shear wall at specified stories is to be assessed.
