The exceptions to the static lateral force procedure that apply to the
simplified procedure are listed in section 1630.2.3.4. Section 1630.6 that
deals with the horizontal distribution of shear is not one of the
exceptions. Therefore, if you have a bona-fide rigid diaphragm, even if you
use the simplified procedure, you still need to distribute your horizontal
shear according to the rigidity of the vertical lateral force resisting
elements.

	I recently attended the SEAOC Seismic Design Manual (Vol. 1) seminar
that
	was held on June 12. During the presentation of determining the
simplified
	design base shear per example 20 in the Seismic Design Manual, I
believe
	that the speaker mentioned that a rigidity analysis would not be
required
	as the loading is conservative using this method. Is this correct?
