I think you need ASME B31Ea-2010.

"When the seismic design force is computed based
on para. 13.3.1 of ASCE 7, or a similar standard, the
parameter ap shall be 2.5 and the parameter Rp shall not
exceed 3.5 when applying the stress limits of para. 3.4.

When the alternative design methods of para. 3.5 are
used, the derivation of seismic inputs shall be based on
parameters compatible with the design method being
utilized."
