本人正在做一带缝的两塔结构，塔1为10层，塔2为4层，一层地下室车库连在一起，全框架结构，6度区，用PKPM08版SATWE计算，不知什么原因塔2上三层刚度比均小于1，均为薄弱层，麻烦哪位知道原因的网友来解释一下。先谢谢了。

===========================================================================
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
