Implementing a Long-Term Bridge Monitoring Strategy for a Composite Steel Girder Bridge
… of Transportation have established a long-term bridge health monitoring system to monitor critical vulnerabilities in a group of bridges throughout the state. This research focuses on a three-span, simply supported composite steel girder bridge carrying three lanes of highway traffic. It has …

Advancements in Satellite SAR Methods for Monitoring Civil Infrastructure
… Radar (SAR) imaging enables large-scale, remote monitoring of civil infrastructure. SAR allows for monitoring without installation or maintenance, unlike traditional contact-type sensors. Whilst SAR interferometry (InSAR) is widely used for land monitoring, its application to bridge monitoring is …

Structural assessment of bridges using monitoring data
… little industry uptake of structural health monitoring (SHM) technologies and model updating techniques, i.e., the integration of structural monitoring data with structural analysis modelling, in bridge operation and maintenance (O\&M) activities. Many bridge practitioners question whether …

Machine Learning for the Condition Assessment of Concrete Bridges
The assessment of concrete bridge conditions is critical for ensuring structural integrity and public safety. Traditional inspection methods, which rely heavily on visual inspections and manual assessments, are time-consuming, subjective, and prone to human error. With the increasing number of …

Physics-Informed Neural Networks for Structural Health Monitoring of Bridges
Bridges are critical components of a nation's transport infrastructure. Structural health monitoring (SHM) is increasingly employed, particularly on key bridges, to track their structural performance and for their effective structural management. Interpretation of sensing data from SHM however …

Collaborative Estimation in Distributed Sensor Networks
… ubiquitous in applications such as air-quality monitoring, oceanography and bridge monitoring, where calibration is often difficult and costly. This dissertation provides an analytical framework linking the state of calibration to the overall uncertainty of the inferred parameters.</p> <p>In …

Structural Health Monitoring for Bridge Structures Using Wireless Smart Sensors
Structural health monitoring (SHM) has drawn significant attention in recent decades because of its potential to reduce maintenance costs and increase the reliability of structures. An important class of structures that can potentially benefit from SHM are bridges, many of which are structurally …

Application of advanced non-destructive testing methods on bridge health assessment and analysis
Bridge structures have an important role in economic, social and environmental aspects of society life. Bridges are also subject to a natural process of deterioration of construction materials, as well as natural and environmental events such as flooding, freezing, thawing etc. Health monitoring …

Validation of the deck behaviour due to post-tension loading of Ashton arch bridge
The new Ashton Bridge is a concrete tied-arch structure with a cable-supported deck, which spans 110 metres below the arching ribs. The tie-beam members, connecting the arch ribs, each have six longitudinal tendons that have primarily straight profiles. The author set out to validate the structural …

Development of a Field Monitoring System for the Northside Drive Bridge
… aims to create a system for real-time structural monitoring of bridges, ultimately offering a reliable method to accurately estimate a bridge’s remaining fatigue life. Standard procedures exist to calculate the remaining fatigue life of steel bridges. However, such procedures rely on conservative …
