concentrated plastic hinges-P-M interaction?

Post by hosseinigelekolai » Sat Jan 25, 2014 2:27 am


i have some problems with concentrated plastic hinges in opnesees:

1-how to consider P-M interaction with concentrated plasticity in opensees?
2-there is an example about concentrated plastic hinge at : ... ment_Frame
but P-M interactions are neglected in this example.

thank you so much

I have asked this question before, and it may be useful for you too. here is the link to the post: ... =2&t=60763
But I have a question from you! why do you want to model concentrated hinge?? one of the main advantages of OpenSees is modeling distributed plasticity! you can use a nonlinearBeamColumn with fiber sections which considers P-M interaction.
