最近研究用ETABS进行风时程动力时程响应分析，再测试算例时候发现，算完弹性时程分析后，点击绘制曲线，弹出如下错误。
Error in recovering Base Shear
history:CSlSAPModelcReadSAPBase::GetBaseShearResponse: CsiGo
ErrorDetails: kFatal = 8
基底剪力数据无法提取，基底剪力时程曲线也无法绘制，但是计算结果已经算完了。同时其他结果都能正确提取出来。
后经过检查，发现是ETABS的BUG，当风荷载采用施加到刚性隔板点的方式是施加时，当施加的楼层过多，计算完后就会出现上述无法提取剪力结果的错误。
于是没办法，只能将风荷载改为施加到指定节点上的方式，结果就正常了。但是施加到指定节点上，明显工作量比直接按楼层刚性隔板施加荷载的方式要复杂很多，而且没办法直接指定施加到刚性隔板点。

Have you fixed this error yet? i’m currently having a similar error about the story drift but i haven’t fixed it yet
After inspection, it was found that it was a bug in ETABS. When the wind load was applied to the rigid partition point, and there were too many floors applied, the above error of not being able to extract shear force results would occur after calculation.So there was no choice but to apply the wind load to the specified node, and the result was normal. However, applying loads to designated nodes is significantly more complex than directly applying loads to rigid partitions on floors, and it is not possible to directly specify the point of application to rigid partitions.
