Re: Interior wood shear wall lateral bracing

I have seen the 5psf out of plane load in the San Francisco code it was
to reduce the risk of a wall falling over in a fire and secondarily for
internal differential air pressures when doors and windows are open and
exposed to exterior wind pressures.

Sheet rock shear can be considered by transferring the out of plane wall
force with blocking. There is no design allowable for sheet rock
connections in compression nor tension.
