Abstract: In bridge weigh-in-motion systems, the vehicle speed is a fundamental input parameter for the weighing algorithm. The speed is generally obtained by processing structural responses measured at different locations along the ...

Abstract: Vibration-based damage detection for civil structures has been actively investigated. Many acceleration-based damage detection methods have been developed, among which the subspace-based system identification theory has ...

Abstract: Establishing an accurate finite-element (FE) model that faithfully replicates the nonlinear behavior of steel–concrete composite girder bridges is crucially important for effective model-based structural health monitoring ...

Abstract: Ambient and vehicle-induced bridge vibration tests are two important ways of collecting data for the purpose of system identification and performance evaluation of bridges. A common bridge form that has been very popular ...

Abstract: Modal properties are recognized as indicators reflecting structural condition in structural health monitoring (SHM). However, changing environmental and operational variables (EOVs) cause variability in the identified modal ...

Abstract: This paper experimentally investigates a vibration-based scour monitoring approach applicable to bridges with multiple simply supported spans on shallow foundations. A monitoring strategy based on the relative changes in ...

Abstract: Bridge modal parameters play an important role in bridge engineering; they can serve as useful indices for many applications, such as numerical mode calibration and updating, and bridge structural health monitoring (SHM). ...
