Structural health monitoring of a curved roadway bridge: model calibration and collapse simulation aspects

This work aims to explore the potential of the Applied Element Method (AEM) for structural analysis application in the framework of bridge monitoring, focusing in particular on the aspects of model calibration and simulation of the collapse behaviour. An AEM model of a curved roadway bridge undergoing slow landslide-induced movements was built and calibrated by using the results of ambient vibration testing and modal identification. A simulation under increasing displacements caused by the landslide was carried out, predicting the deformation evolution of the bridge and comparing it with the current state of damage observed on site.
