The interim Guidelines Advisory No. 2 of SAC99-01 is very helpful to me in
the design of moment-resisting frame. Thanks for the hard work.
I have a question on the 0.9 reduction of Fy stress used to limit the
through-thickness stresses on the welding to the column flanges. Can
someone help me find out the origination of this recommendation. Is it
because the coupons are taken from the web?
