Over the last decade, the rapid expansion of Global Navigation Satellite Systems (GNSS) coupled with the incremental improvements on the existing GPS constellation has continuously increased the robustness of satellite positioning, therefore significantly improving the reliability and the possibilities of a GNSS-based structural health monitoring s...
This article addresses the subject of data-driven structural health monitoring and proposes a real-time strategy to conduct structural assessment without the need to define a baseline period, in which the monitored structure is assumed healthy and unchanged. Independence from baseline references is achieved using unsupervised discrimination machine...
Detecting and assessing the severity of structural damage is one major objective when monitoring a bridge. In particular, when some degradation phenomena threaten the bridge safety, the goal can be to assess monitoring critical components, which allows checking a safety threshold is not reached until some repair/rehabilitation actions are performed...
Rehabilitation and retrofitting can produce effects on structures which may not always be entirely predicted. Structural health monitoring can be of good use during bridge works, which may have to be carried without traffic interruption. In this work a technique based on cluster analysis is used to distinguish structural states before, during and a...
Suspension bridges and their main cables are designed for a service life of over 100 years. Hence, the health of such cables is one of the main issues for bridge owners. In this article, pathologies, loading conditions and inspection requirements are discussed. Critical aspects of structural health monitoring of bridge cables are identified.
Cette recherche a pour objectif le développement de modèles pour l'étude de la résistance résiduelle d'un câble de pont suspendu. Elle vise ainsi à fournir des éléments d'estimation de la résistance d'un câble à partir de la description de son état actuel, d'évaluation du risque de rupture d'un câble à un niveau de sollicitation imposé, et enfin de...
