Steel connection for beam supporting girder
Steel connection for beam supporting girder
(OP)
I have a situation where a cantilevering beam is supporting a perimeter beam/girder. See attachment.
Does having the perimeter beam be continuous pass the supporting beam with a splice a couple feet away from the supporting beam put eccentricity into my double angle connection? I think not but im second guessing myself and can't find a design example with this situation.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

This deformation will cause one of two things to happen.
1) The connection will be flexible enough (short slotted holes) to allow the rotation without imparting any force into the supporting member.
2) The connection will be rigid enough that it will impart some torsion into the supporting beam... until the two rotations are equal.
That being said, I beams are very flexible in torsion. So, I have a hard time believing that the torsion that develops will be significant. To the point where the torsional force induce in the beam is practically equal to zero and can be ignored for design.
