roller coaster model

[joanrizu]

I am checking an existing roller coaster steel structure. We have original drawings but I need to check the model. Does any body know how could I model dynamic car loads with etabs or sap? Thanks,

If you are choosing between SAP2000 and ETABS for this analysis, definitely go with SAP as ETABS is primarily for buildings and other non-complex structures.
