Re: Error of 'ForceBeamColumn' element

Thank you for answer.

As you have mentioned, I have applied the 'displacementBeamColumn'.
But it continue to stop working on the opensees, can you tell us why?

Thank you

Error of 'ForceBeamColumn' element

I received a cable bridge structure model built with Opensees, but the problem is that only the linear behavior is applied and the displacement is very small. So I used the 'ForceBeamColumn' element to take into account the material nonlinearity only in the pylon, but only the part of the changed el...

FORM (FFD analysis)

Hi
I have a question about reliability analysis used opensees.

I know it is possible to compute DDM(Direct differentiation method) based sensitivity.
But is it possible to compute FFD(Forward finite difference) based sensitivity?
