Solving P-Delta Diverging at a Node in RISA-3D

In this video, you’ll learn how to investigate errors in your RISA-3D model for P-Delta diverging at a node. This type of error is common in general structural analysis software and has two major causes: a model that is unstable or a model that is too flexible. For this investigation, two separate steel frame models will be used to evaluate a workflow to solve P-Delta issues.
