采用IS：1893反应谱方法计算地震荷载，在校核层间位移时给出，给出如下警告: WARNING: THE LOAD COMBINATION# 171 CONTAINS 1893 RESPONSE SPECTRUM LOAD CASE. STORY DRIFT IS NOT CALCULATED. 请问怎么解决？

在帮助文档AD.2007-09.2.4 Check Story Drift中提到一点For dynamic IS 1893: 2002 response spectrum, the story drift check is performed by adding a command line within the load case, rather than in the post-analysis print commands. Refer to Section 5.32.10.1.2 of the Technical Reference Manual for additional information.

意思大致是如果对于印度规范的反应谱工况，则层间位移打印命令需要定义在工况里面，而不是post-analysis 里设置。

请按照这个要求改一下，再查看警告是否消失。
