Section J4 of the AISC Specification for Steel Buildings (AISC 360-16) provides equation J2-5 to account for the weld directional strength increase.
This increase factor may be applied; "IF STRAIN COMPATIBILITY OF THE VARIOUS WELD ELEMENTS IS CONSIDERED."
I believe the stipulation regarding strain compatibility is due to the loss of weld deformation capacity as the strength increases.
My question: Can anyone kindly provide an example of a welded joint where lack of strain compatibility between the welded elements would disqualify use of this increase factor?
I believe I understand the theory, but I'm having trouble coming up with a practical example where this comes into play.
