Info on modelling a beam subjected to rotation
(OP)
Hi
I am to modeling in ABAQUS. I am currently modeling a RC coupling beam. My load for this beam is however rotational ( I have attached the figure describing the rotation. I modeled the concrete as a solid, however I tried various approaches trying to model the load on the beam.
1. I tried inputing the rotations in the form of rotational body force.
2. I tried entering the load as a rotational BC.
3. With the both the methods I tried kinematic coupling.
When I went over some of the posts here I realized that rotational dof for solid cannot be mentioned (??).
I open to any suggestion on how to go about modelling this

RE: Info on modelling a beam subjected to rotation
Solid elements have only translational degrees of freedom, so yes, you can't apply rotation on them.
Try adding some beams to the solid just to pass the rotation from the beams to the solid (beam with negligible stiffness). I have no idea although how good is my idea, but I can't get any better idea right now.
