Dear Ray Delaforce,

Is it recommended to use PV-elite seismic analysis in the above case?
or, Is it valid if I do seismic analysis by dividing equipment into 2 or 3 segments (by maintaining 2 saddles in one part segment of the equipment).

Also, can you explain the difference between "IS 1893 Code Edition:2005 Simplified calculation & 2015 calculation), in my case, I have site spectrum date is available w.r.t to time period & sa/g values.
IS 1893 Code Edition: 2005 Simplified calculation is failed but IS 1893 Code Edition: 2015 is passed.

by considering what case do I need to select them? Please advice


Thanks & Regards,
Chaitanya
