Tributary width for uplift calc. in light gauge wall studs

Tributary width for uplift calc. in light gauge wall studs

Tributary width for uplift calc. in light gauge wall studs

(OP)
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?

RE: Tributary width for uplift calc. in light gauge wall studs

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.
