  Hi There -
  
  I'm trying to model a precast shearwall consists of two segments and connect those segments with connectors. the connectors should behave as non-linear springs. I coded the springs as follow:
  
  et, _sid,39
  
  keyopt,_sid,4,1
  
  R,_sid,-3,-1300,-0.5,-1000,0,0
  
  RMORE,0.5,1000,3,1300
  
  everything ran as expected and I'm happy with the results. My question is, is there a way that I can get Loading hysteresis for loading and unloading as shown in the attached pic?
  
  any help is appreciated
