CSIbridge nonlinear analysis for a step in moving load case
CSIbridge nonlinear analysis for a step in moving load case
(OP)
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?





RE: CSIbridge nonlinear analysis for a step in moving load case
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.
