Long term health monitoring of post-tensioning box girder bridges
A number of efforts had been sought to instrument bridges for the purpose of structural monitoring and assessment.The outcome of these efforts,as gauged by advances in the understanding of the definition of structural damage and their role in sensor selection as well as in the design of cost and data-effective monitoring systems,has itself been difficult to assess.The authors’ experience with the design,calibration,and operation of a monitoring system for the Kishwaukee Bridge in Illinois has provided several lessons that bear upon these concerns.The systems have performed well in providing a continuous,low-cost monitoring platform for bridge engineers with immediate relevant information.
