plastic rotation of BWH element

Post by caosasa » Wed Oct 31, 2012 5:26 am

Dear Vesna,
i am confused about your comments on recorder of plastic rotation of BWH element.
in the two post of "I cant record rotation and stiffness for beamwithhinges"(2006) and
"beamwithhinges element recorder"(2010), you said:
"beamWithHinges element does not have recorder for plastic deformation. You will have to use curvature for this."
and "You can record force at the section but plastic rotation is not related to section but to plastic hinge region so
you can not record it at the sectional level." respctively.
here is my question:
Given that element 1 is BWH element,
what does the recorder"recorder Element -xml Data/Element1.out -time -ele 1 plasticRotation" give?
plastic rotation of hinges or plastic curvature of hinges?
Thank you in advance.

Provide links for posts instead of cutting out of contest parts of the sentences. That is the best way to confuse someone.

I never sad that you can not record plasticDeformation of BWHs element. What I might have sad before is that several users complained about this recorder option for force-based element.

"plasticRotation" argument allows you to record plastic rotations, not curvature.
