GYPSUM BOARD SHEATING FOR WOODEN STUDS
GYPSUM BOARD SHEATING FOR WOODEN STUDS
(OP)
Is Gypsum Board Sheating Allowed For Wooden Studs? If it is, where can we get the shear capacity.
In UBC 1997, Values for allowable shear load of Gypsum Board Sheating with corresponding nail spacing is only for metal studs, thhere is no value for w00d studs. tnx

As to what Taro said about not relying on gypsum. Yes, plywood is stronger and is a ductile type of failure, but gypsum is stronger than most people(including the code) give it credit for. The reason the values are lower is because it is a brittle failure mechanism.
For high siesmic regions gypsum is prohibit from being used to resist earthquake forces anyway. For wind controled lateral forces it is fine material. Keep in mind though the aspect ration cannot be reduced from 4:1 like plywood can in lower siesmic zones.
