Nonlinear Elements, Elastic Sections

There's very little reason to use the elasticBeamColumn element in OpenSees. Using nonlinear elements, particularly the forceBeamColumn element, with elastic sections is just as good, if not better for many reasons. Not only do force-based elements with elastic sections make the transition to material nonlinearity easy, they also facilitate debugging your model. Another reason I … Continue reading Nonlinear Elements, Elastic Sections
