• A damage localization and quantification algorithm for indirect structural health monitoring of bridges using multi-task learning

  AIP conference proceedings · 2019-01-01 · 23 citations

  articleOpen access

  We propose a multi-task learning approach for estimating both the location and magnitude of damage occurring on an experimental bridge using acceleration signals collected from a passing vehicle. This is a low-cost and low-maintenance indirect structural health monitoring approach in which sensors on the vehicle are used to detect bridge damage. Recently, signal processing and machine learning approaches have been shown to perform well in achieving higher-level structural health monitoring objec…

• Dynamic responses, GPS positions and environmental conditions of two light rail vehicles in Pittsburgh

  Scientific Data · 2019-08-12 · 18 citations

  articleOpen access

  We present DR-Train, the first long-term open-access dataset recording dynamic responses from in-service light rail vehicles. Specifically, the dataset contains measurements from multiple sensor channels mounted on two in-service light rail vehicles that run on a 42.2-km light rail network in the city of Pittsburgh, Pennsylvania. This dataset provides dynamic responses of in-service trains via vibration data collected by accelerometers, which enables a low-cost way of monitoring rail tracks more…

• Detecting anomalies in longitudinal elevation of track geometry using train dynamic responses via a variational autoencoder

  2019-03-27 · 14 citations

  article

  Track geometry is one of the most important health indices in the maintenance of rail tracks. Visual inspection and inspection using a track-geometry car are two common approaches to inspect track geometry. Presently, using accelerations from in-service trains has become a popular track inspection approach, because it is a low-cost way to monitor the rail tracks more frequently. However, due to the noise presented in the collected accelerations, detecting anomalies using manually designed featur…

• An Expectation-maximization Algorithm-based Framework for Vehicle-vibration-based Indirect Structural Health Monitoring of Bridges

  2019-11-15 · 6 citations

  article

  We propose a vehicle-vibration-based indirect structural health monitoring (SHM) framework that uses acceleration signals collected from within a moving vehicle to identify global modal and structural parameters of a full-scale and in-service bridge. Motivated by many benefits of indirect sensing methods, such as low-cost, low-maintenance and no interruption to traffic, researchers have in the past presented different algorithms and evaluated them on several simulation and lab-scale datasets. Ho…
