Question

How is the varying longitudinal stiffness of ballast/concrete bed considered for rail track analysis?

Answer

For Rail Track Analysis, Multi linear elastic links are used to simulate the bilinear curve of longitudinal stiffness for loaded and unloaded conditions of ballast/concrete bed connecting rail and superstructure

The multi-linear link data is available under “MEInk” Tab, in the table of Elastic link data.
