Title

A Bridge Damage Detection Approach Using Vehicle-Bridge Interaction Analysis And Neural Network Technique

Abstract

This paper is intended to develop an economical and convenient method bridge identification approach based on Neural Network (NN) technique using dynamic bridge responses induced by the running vehicles. In the proposed approach, a NN for bridge damage identification is established using the running vehicle-induced bridge vibration data as input and the structural damage condition as output. To develop such a system, the possible damage patterns of the bridge are assumed according to theoretical and empirical considerations at first. Then, the running vehicle-induced dynamic responses of the bridge under a certain damage pattern are calculated employing a developed vehicle-bridge interaction analysis procedure. The obtained structural vibration responses are then used as training data to establish the NN system. In this paper, the basic process of the proposed approach and the evaluation of its feasibility are indicated using simple numerical bridge and vehicle models. © 2012 Taylor & Francis Group.
