Tributary width for uplift calc. in light gauge wall studs

[DavidStructural08]

I happened to notice that people used different loads from different tributary width to calculate the uplift in light gauge column, e.g., for a 24" studs, 24" is the tributary width for compression while 5' or 6' may be the one used in uplift.

I am just wondering if there is any code requirement on this, probablly from AISI?

Are you talking about pressure and suction on wall studs? If so, the tributary, per ASCE 7 is (height of stud)^2/3.

Thanks Dave, but no, I was talking about the downward axial force on wall studs which are parts of shear wall.
