Hello,

I have a question concerning the recorders in opensees. I have a rigid beam element of 1m dimension in x-x (node1 ... node2) and I would like to record its rotation. The analysis is elastic in 2D. I used this record for one of the nodes of my element:

recorder Node -file DBase.out -time -node 1 -dof 3 disp; # displacements at found

Can anyone help me? The record I used gives displacement due to rotation, rotation or relative vertical displacement/element length? How can I record the element elastic rotation (in rad) in one step?

Thank you very much
With my best regards
AK

The recorder you used gives you rotation of node 1. If your element is rigid the rotation of the element should be the same as rotation of the node.
