IBC Effective Seismic Weight
IBC Effective Seismic Weight
(OP)
Do I understand the IBC right that as long as the area is not used for storage no portion of the Live Load needs to be included in the effective seismic weight, except permenant equipment? Don't most people include a portion of the live load to account for things such as furniture, occupants...ect.?

If you are talking about a deck on a rooftop where people assemble, I would definitely include it.
Regarding the issue of drift or flat, I would use the worst case considering that the flat snow load condition would occur with no wind, and the drift with wind in your load combinations.
