Question about top flange joist hanger connections to W shape beams
(OP)
I am detailing joist connections to W shape beams. (see attached) In some cases I have joists on only one side of the beam and I am concerned about torsion on the beam. But even where I have joists with equal spans on both sides of the beam there might be live load on only one side. These are commonly used joist hangers, however I don't feel comfortable ignoring the torsion. Two questions: Is it common to ignore the torsion? If not, then how do I brace the steel beam to resist the twist?

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.

I have no idea what you guys are talking about which leads me to believe that I may have a past/future problem on my hands. Can either of you expand upon this?

RE: Question about top flange joist hanger connections to W shape beams
My guess is this:
Certain metal hangers require that there be a wood block at the end of the beam/joist. "Backer block" might be the better term of this.
USUALLY this is when a top flange style hanger also has nails in the "sides" -OR- when a top flange style hanger is attached to a "I-joist" header.
Many hanger conditions do not require this but it might look "weird" and .... you know how some plan examiners can be...
