May I look on diaphragm design forces Fpx as shears in diaphragms? 1

See ASCE 12.10.1.1 “floor and roof diaphragms shall be designed to resist design seismic forces …………… in accordance with eq. 12.10-1”.

If I design a floor diaphragm (wood structure), or slab (concrete or steel structure), May I use Fpx (calculated from 12.10-1) divided by the floor length as a unit shear of the floor? Thanks
