Combined Stress on Weld
Combined Stress on Weld
(OP)
My question comes after talking to someone about the (CJP, for discussion) weld at the base of a round vertical pipe to a transverse base plate. (think light pole design).
I've seen this interaction equation published...somewhere...but I can't recall where:

Can anyone point me to a published reference for this equation?
Thanks!
Vu = effective weld stress per unit length (kips / inch)
d = pole / weld diameter
Fx = axial load, Fz,Fy = base shear
Mx = torsion, Mz,My = moments
Aw = weld area, Sw = weld section modulus, Jw = polar moment of inertia

I cannot find the publication of the formula you are looking for however this link shows how to calculate fillet welds for strength for all types of loading.
