Dear all, I am trying to simulate cyclic test in Perform 3D by using displacement control. My goal is to make the hysteresis curve. I have defined a series of consecutive static pushover analysis, consists of positive and negative pushover load cases. However, I found that each pushover case only used the preceding gravity case, instead of the previous pushover case. As a result, each pushover case gives independent Force - Displacement curve without considering the unloading stiffness. Is there any better approach how to do this?
I have attached my analysis setup for your insight.
