Track structure interaction as per UIC 774-3R

Hi everyone,

Does anyone have references or examples in Sofistik to evaluate the effect of track structure interaction according to UIC 774-3R, particularly for continuous bridges with a single fixed pier?

I am working on a Sofistik model to analyze the restraint effects of an unballasted track on the deformation of the bridge deck. Any guidance or shared experience would be greatly appreciated.

Thank you in advance!
