Convoluted Reciprocity and Other Methods for Vehicle Speed Estimation in Bridge Weigh-in-Motion Systems
Publisher: ASCE
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 ...
Vibration-Based Damage Detection for a Prestressed Concrete Box Girder by Means of Subspace Analysis
Publisher: ASCE
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 ...
Ambient and Vehicle-Induced Vibration Data of a Steel Truss Bridge Subject to Artificial Damage
Publisher: ASCE
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 ...
Data Normalization and Anomaly Detection in a Steel Plate-Girder Bridge Using LSTM
Publisher: ASCE
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 ...
Experimental Demonstration of a Mode Shape-Based Scour-Monitoring Method for Multispan Bridges with Shallow Foundations
Publisher: ASCE
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 ...
Extraction of Bridge Modal Parameters Using Passing Vehicle Response
Publisher: American Society of Civil Engineers
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). ...
