pushover

[GALLO ANTONIO]

hi, I have a problem.
I used two types of models to make the analysis
pushover. In the first model I used
nonlinearBeamColumn element in the second model I
used dispBeamColumn element.
The pushover curve obtained with the second model
is about double compared to the first model.
is such a thing possible?
thanks.

It may happen if you just replace a nonlinearBeamColumn element with a dispBeamColumn element. The results you get using dispBeamColumn element are not correct. To get the same response you need more dispBeamColumn elements.

Thanks so much.

Hello,

I've used beamWithHinges and dispBeamColumn, but I haven't used nonlinearbeamcolumn. Can you please tell me where the documentation is for that element? I have looked at the Element Command page on the Wiki, but it's not there.

To address the original question, would adding more integration points be a way to improve the output from the element?

Thanks

Here is the documentation for nonlinearBeamColumn element.

Adding integration points to dispBeamColumn element would not bring you to the same solution.
