Beam to Beam moment connection
Beam to Beam moment connection
(OP)
You have two beams framing into a girder, one on each side. The two beams are in line. One beam is a cantilever fastened with a moment connection to the girder. Can the other beam be a simple shear connection or does it have to be a moment connection? I have seen it designed both ways. It has been said that since the other beam frames into the girder opposite the moment connection, that beam will stiffen the girder enough to resist the torsion created by the cantilever. Can anyone tell me if this is true or what is industry standard. Where can I find literature on this?
Most of the time we put a moment connection on both sides of the girder.

RE: Beam to Beam moment connection
If the main girder is designed to resist the vertical reaction plus the torsion from the cantilever, then the other connection may be 'pinned'.
If however the main girder is designed to carry the vertical reaction only, and you are relying on the second beam member to resist the moment from the cantilever, then both connections will need to be moment connections.
