Gyp Shear wall capacity
Gyp Shear wall capacity
(OP)
I was looking for general thoughts on shear wall capacity.
IBC 2306.4.1 allows a 1.4 increase to table 2306.4.1 for wind design for wood structural panels.
I don't see a similar increase allowed for gyp from section 2306.4.5. Is there one? I also don't see a reduction for specific gravity of species framed into. None required like WSP?
Thanks.
Also, if anyone has any insight into the basis behind the 1.4 increase I would love to know. The 2306.4.1 table is for seismic and wind, and then calls later for a 1.4 increase for wind. I was trying to calc back for duration factors of 1.33 for seismic and 1.6 for wind but wasn't getting anywhere.

For permanent, 0.9/1.6 = 0.5625
For live load, 1.0/1.6 = 0.625
