CSIbridge nonlinear analysis for a step in moving load case

[kww2008]

I require a nonlinear analysis for a vehicle at a position on a bridge. Nonlinear analysis because the model has nonlinear gap and link elements. I cannot carry out a NL analysis using statics multi-step analysis, and I do not want an influence surface analysis using a moving load analysis. Could someone suggest how I go about doing this?

Either of this two:

Define NL deal load case and then start your ML case from the stiffness of NL dead load
Or Use Time history analysis with small time-steps again with stiffness from NL case.
Your stress-strain curve can be either default in CSI or can quickly make your own points from theoretical or experimental data.
