一字型剪力墙计算长度分析

Analysis on the Effective Length of the Shear-wall Without Flange

一字型剪力墙在稳定分析中往往被简化为两边支撑的矩形薄板,而高层建筑功能日益复杂,一字型剪力墙实际的稳定分析不能按规范一概而论。从楼板与墙肢长度比值,楼板与剪力墙线刚度比,剪力墙开洞率三个方面着手,通过对一字型剪力墙的稳定分析得出计算长度系数的变化,给工程实际提供参考。

The shear-wall without flange in the stability analysis is often simplified as two sides supported rectangular thin plate,as high-rise buildings function increasingly complex,the shear-wall without flange in the stability analysis actually cannot generalize by norms. Starting from three aspects:the ratio of floor length to wall length,the linear stiffness ratio of floor to shear wall,and the hole opening rate of shear wall, through the stability analysis of the shear-wall without flange,the change of effective length coefficient is obtained,which provides reference for the engineering practice.
