A Distributed Vision‐Based System for Cost‐Effective Fault Diagnosis of Modular Bridge Expansion Joints

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Detecting faults in modular bridge expansion joints (MBEJs) is a critical challenge, as their complex dynamic behavior under operational loads is difficult to characterize with conventional methods. Existing monitoring approaches often face a trade‐off between high cost, intrusive installation, and an inability to capture the distributed kinematic ...
