Chord rotation recorder

[Diegoh]

Hello,

What does the chord rotation recorder do in a force-based beam column element? I am modeling a cantilever column with axial and lateral loads, and I obtain a non zero chord rotation at the free end. I am not sure why this happens since the inflection point is at the free end.

Thanks a lots for your help

The chordRotation recorder gives the basic deformations of the element - axial deformation plus nodal rotations relative to the element chord.
