Re: Diaphragm design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
My two cents...
The collector element to the shearwall would need to
be designed for the Omega overstrength.  the design of
the dowels themselves from the concrete fill to the
shearwall would be just the nominal unit shear = 500k
/ wall length, and not necessarily the 30' length of
s.w.
