RE: Steel stud framed shear walls

[Subject Prev][Subject Next][Thread Prev][Thread Next]
You are right.  UBC 18 and 20 gauge studs allowed if you are using #8
screws.  For 16 gauge studs 10 gauge screws are reported to work but no
supporting paperwork to back you up.

Subject: Steel stud framed shear walls

Greetings comrades-in-arms:  A question about steel stud shear walls: Table
22-VIII-C in the 1997 UBC, footnote 2, limits the base metal thickness to
0.043".  Does anyone know why this is?  I suspect that the intent is to
ensure dutile response of the wall as maybe a thicker base metal would
restrict deformation of the screw-stud connection.  The 2000 IBC doesn't
have this restriction.
TIA for any insight.
