Spectrum analysis - interstorey drift

Spectrum analysis - interstorey drift

(OP)
Can anyone help me with an easy method for determining the inter-storey drift from an ANSYS Spectrum analysis.  PRNSOL only gives the nodal displacements not inter-storey drifts.  Storey drifts cannot just be calculated by subtracting the final nodal displacements which have been evaluated by for example CQC.  Storey drifts have to be computed for each mode and then CQCed at the end.

I have tried many tricks up my sleeve including ETABLE stuff, trying POST26 commands, but have reached a deadend.  Is the only option I have to write an APDL macro to do it.  This would not have been too much of a problem if I was using SRSS, but with CQC, wow, it really gets complex. Any ideas
