Drift Recorder considering flexible base

[RaminZ]

Hi everyone,

I have a question regarding calculating drift ratio while the base is flexible (soil-structure interaction case). When the base is fixed, the drift would be the difference between displacements of two consecutive floors. However, when the base is flexible, an additional term, base rotation*story height, has to be added to or reduced from the previously defined drift. Here is the question: Does "drift recorder" command consider this term?

Thanks guys.
