https://portwooddigital.com/2022/07/03/elastic-shear-beams-in-opensees/ Thank you so much for your reply. Your blogs are really informative and helpful. I understand that if I define an elastic section in which the shear modulus is given, then assign the section to a force-based beam-column element...

Hello all, I am wondering if the shear deformation is considered when I use Force (or Displacement) -Based Beam-Column Element with fiber sections? If shear deformation is considered, how the shear modulus is calculated? A more general question is, for such questions, where can I find the mathematic...

Have you tried to use more elements and finer fiber mesh?

By the way, what do you mean by "material regularization"? Could you please give more information on it? Thank you.

The local y and z axes are arbitrary in 3D, so you have to define the local y axis. I'm guessing you want it to be 1,0,0 Thank you Prof. Scott! This is really helpful. Yes, I want the local y axis to be [1,0,0] in this case. So I would have to define the local orientation explicitly as: '-orient', ...

Hello everyone, I have a question about how the local y axis of a twoNodeLink element is determined in 3D model, in case I am not defining it explicitly. Say I have two nodes: node(1, 0,0,0) node(2, 0,1,0) Then I define a twoNodeLink element as: element('twoNodeLink', 1, *[1,2], '-mat', *[1,2,3], '-...
