INTERFACE ELEMENT FOR THE DYNAMIC ANALYSIS OF VEHICLE-STRUCTURE INTERACTION

INTERFACE ELEMENT FOR THE DYNAMIC ANALYSIS OF VEHICLE-STRUCTURE INTERACTION

Durand, R.; Silva, D.A.; Brito, J.L.V.

Full Article:

In current literature, there are several approaches for the numerical study of the vehicle-structure (e.g. train-bridge) interaction problem. One of the most prominent ap-proaches combines both vehicle and structure systems into a single one through the use of special interaction elements. In this work it is proposed a different method that joins vehicle and structure by introducing an interface element. This element automatically makes forces and displacements compatible at contact nodes. The method is applicable for the study of interaction of concentrated loads, vehicles and train compositions. The method was applied to the study of a concentrated load moving on a bridge obtaining excellent results when com-pared to analytical ones. Finally, an analysis of a passing carriage over a bridge is made.
