Structural beams and bars in non-linear analysis of QUAKE/W

I need to study the dynamic non-linear response of reinforced soil wall with anchors. Hence, I used structural beams for reinforcement and structural bars for anchors. However, there was error in the model which displays "Structural beams and bars cannot be specified with a non-linear analysis in QUAKE/W"

What can be done to proceed with my non-linear analysis?

Kindly help

    Hi Sureka, thanks for reaching out. Unfortunately, it is indeed a limitation of the formulation of the non-linear constitutive model. The model is not a conventional elastic-plastic constitutive models like PM4Sand/Silt. The implementation required special numerical procedures that made it challenging to accommodate structural elements.  The Equivalent Linear model would have to be used.
