Did this factor play any role in the Northridge Disaster? (I don't think so
but I'm interested in hearing from others!!)

Subject: RE: Welding across the flange?
The concerns of welding across a flange in general is to broad of a area for
generalization. The penetration, loading, and stresses at and around the
weldment is necessary for proper evaluation.
Although, welding does not reduce the strength of a ductile steel such as
A36 (upon cooling down), it does change the metallurgical make up, resulting
in relative brittleness.
In contradiction to the aforesaid I offer the following , it may be a
fatigue issue (i.e. stress riser) generally speaking.
