I have a tube with a torque on it. I'd like to resist this torsion through beam framing into each side (perpendicular to the main beam with the torsion on it). However, the connection will only transfer shear forces. What are my options for modelling this?My first thought is that I could add a dummy member extending from the beam with Torsion equal to half the width of the beam. Then use a release between the dummy member at the perpendicular member. Do i have other options here?
See image below:
I think you could use rigid offsets too, but there is nothing wrong with dummy member, stub-cantilever approach here. Maybe the end of the girder should be fixed rather than pinned.
Thanks for the response. I actually would like the end to only be pinned. Torsion is not resisted at ends in this case. Regarding the rigid offset - would that be applied to the perpendicular member? If I released rotation would it still resist the girder from spinning about it's axis? My first thought was that it would not (that's why I went the 'dummy member' route).
