| Abstrait: |
Estimation of coupling parameters is the key for calculating the interaction between embedded rail system (ERS) and a bridge. It was proven recently that material parameters of polymer-based elastic poured compound (EPC) and other parts of ERS are subjected to change with temperature and displacement rate. Both effects have been discussed in the scientific literature quite thoroughly. However, very little is known to this day about how to address the displacement-rate along the bridge. Therefore, a new engineering approach for analyzing the bridge-ERS track relative displacement-rate is discussed in this contribution. What parameters are affecting the displacement-rate in the ERS? How is the displacement rate in ERS longitudinally distributed? How should be the displacement rate in ERS calculated considering longitudinal and vertical loads? These questions are answered in the paper based on the results of a vast parametric analysis. |
