Current health monitoring approaches for large structures mostly rely on a combination of
distributed sensor networks and in-situ inspection. This paper presents a novel online …

Physics-based digital twins often require many computations to diagnose current and predict
future damage states in structures. This research proposes a novel iterative global–local …

The US navigable infrastructure is a system of waterways dependent upon hydraulic steel
structures (HSS) to facilitate the passage of ships and cargo. The system is linear in the …

The US inland navigation system facilitates the transportation of billions of dollars of goods
annually, with lock gates being a major component of the system. Miter-type gates are the …

The inland navigation system in the US is a civil infrastructure network that relies on the
performance of a vast array of infrastructure assets scattered across the nation to function …

Continuous monitoring of miter gates used in navigation locks is desirable in order to
prioritize maintenance and avoid unexpected failures. Substantial economic losses to the …

Due to the aging of civil infrastructure and the associated economic impact, there is an
increasing need to continuously monitor their structural and non-structural components for …

Some recent work on Bayesian finite element (FE) model updating of civil/structural systems
performed in our lab at UC San Diego is summarized in this paper. The FE model updating …
