Rail-Structure Interaction for Horizontally Curved Decks
Rail-Structure Interaction for Horizontally Curved Decks
(OP)
Dear All,
I am involved in a nonlinear rail-structure interaction (CWR) analysis for a horizontally curved transit bridge. The analysis that I am doing is as per UIC-774-3. I cannot find any clause on how to deal with interaction for acutely curved bridge decks. The curvature in my bridge is about 100m (almost L shaped). Can anybody please suggest any method for analysing this type of bridge for rail-structure interaction? Is there any standard that specifies something for track-structure interaction for curvatures?
Thanks,
Abhishek

Have you thought of breaking it in half?
One is a just a straight transit bridge and the other is a curved rail. The trick will be combining the results into a defendable answer.
The curved rail analysis would give you the loading for the transit bridge in three axis.
