Instead of creating multiple bridge models with different boundary conditions for differential settlement, and combining the forces output manually in Excel, is it possible to specify different boundary conditions within the same model, using different load cases?
I am using both MIDAS and SAP v18 software and I would like to know if there is any way to do this in any bridge structural modelling software. Or is there any software that doesn't require you to add a restrain to a node for which you are applying a movement?
This limitation on the software introduces significant additional effort on the part of the Engineer. Has anyone thought of some way to overcome this issue when dealing with differential settlement or other soil movements?
