Title: One-year dynamic monitoring of a bridge: Modal parameters tracking under the influence of environmental effects
Issue Date: 2009
Abstract: : In order to evaluate the usefulness of approaches based on modal parameterstracking for Structural Health Monitoring of bridges, on September of 2007 a dynamicmonitoring system with 12 accelerometers was installed on a concrete arch bridge that spans280m over the Douro River at the city of Porto, in Portugal. This paper characterizes the bridgeand its modal parameters (identified with an ambient vibration test), describes the monitoringhardware and the implemented software, reports the results obtained with the algorithmsdeveloped for the modal parameters automatic identification and characterizes the influence ofthe environmental temperature and traffic intensity on the identified modal parameters.
