请教高手,等效侧移刚度的计算问题,转换层上下部分数据如下
===========================================================================
各层刚心、偏心率、相邻层侧移刚度比等计算信息
Floor No : 层号
Tower No : 塔号
Xstif,Ystif : 刚心的 X,Y 坐标值
Alf : 层刚性主轴的方向
Xmass,Ymass : 质心的 X,Y 坐标值
Gmass : 总质量
Eex,Eey : X,Y 方向的偏心率
Ratx,Raty : X,Y 方向本层塔侧移刚度与下一层相应塔侧移刚度的比值
Ratx1,Raty1 : X,Y 方向本层塔侧移刚度与上一层相应塔侧移刚度70%的比值
或上三层平均侧移刚度80%的比值中之较小者
RJX,RJY,RJZ: 结构总体坐标系中塔的侧移刚度和扭转刚度

高位转换时转换层上部与下部结构的等效侧向刚度比
============================================================================
转换层所在层号= 3
转换层下部结构起止层号及高度= 1 3 8.90
转换层上部结构起止层号及高度= 4 6 8.70
X方向下部刚度= 0.8378E+07 X方向上部刚度= 0.1378E+07 X方向刚度比= 0.1608[/COLOR]
Y方向下部刚度= 0.1356E+08 Y方向上部刚度= 0.2443E+07 Y方向刚度比= 0.1761[/COLOR]
不知各位在建模时是否包括地下室?如果包括地下室,转换层下部的刚度肯定大于其上部的刚度,那《高规》附录E.0.1,E.0.2,岂不是很容易满足? |
