ASCE 7-05 Section 12.7.1
(OP)
Has anyone ever used this section before. If so what does it mean and when does it apply. It states:
"Foundation Modeling. For purposes of determining seismic loads, it is permitted to consider the structure to be fixed at the base."
"Foundation Modeling. For purposes of determining seismic loads, it is permitted to consider the structure to be fixed at the base."

If you're new to seismic design, I would suggest discussing this with someone in your office (?) who may be knowledgeable, as it's a pretty important concept for seismic design.

You mean higher displacements and lower loads?
RE: ASCE 7-05 Section 12.7.1
But you still have to stay within the allowable drift limits, which may not be too much of a concern.
More often than not, your sections will be drift-controlled rather than strength.
