Gypsum for Shear Wall in SDC D
Gypsum for Shear Wall in SDC D
(OP)
In the 2003 IBC Table 2306.4.5 gives allowable shear for Gypsum Board on framed walls. Footnote a. states that the values are for SDC A,B, and C. I don't see anywhere in the code that specifically prohibits use of gyp board for shear resistance in SDC D. Is it permitted in SDC D? And where is it in the code? If it is permitted what are the allowable values?






RE: Gypsum for Shear Wall in SDC D
Note if you switch to light gauge framing (See IBC secton 2211) there are allowable shear values that can be used for gyp sheathing but they are only applicable for wind loads, not seismic, however one can use light gauge framing in SDC D, E, F if using osb or plywood sheathing (See table 2211.1.(3))

Thanks, that was exactly what I was looking for. It's also covered in the 2001 NDS Wind/Seismic Supplement which I overlooked.
