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(剪切刚度)
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
RJX1，RJY1，RJZ1: 结构总体坐标系中塔的侧移刚度和扭转刚度(剪切刚度)
RJX3，RJY3，RJZ3: 结构总体坐标系中塔的侧移刚度和扭转刚度(地震剪力与地震层间位移的比)

本层侧向刚度小于相邻上层的50%为特别不规则是通过
Ratx = 2.8277 Raty = 2.9986这个来看的吗？大于2就是特别不规则
