Re: drywall type shearwalls- l

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Isn't this why we have fire rated systems?  If it's done right,
you shouldn't have to compromise the structural integrity of
the building to meet the fire code requirements.  I realize that
I don't know the entire story, just a thought.

Even if wind controls, don't you still have the possibility of
seismic loading?
