• Abstract:
  Fatigue-induced cracking is a common failure mode in many steel bridges reaching their original design life. These aging bridge structures have experienced increasing traffic volume and weight, deteriorating components as well as a large number of stress cycles. Despite years of research in overcoming these challenges, catastrophic failures (e.g., the interstate 35W bridge collapse in Minneapolis, MN in 2007) still occur, which is mainly due to various difficulties in detecting bridge health conditions under highly uncertain operational conditions and also our limited understanding of the failure mechanisms in these systems. This project strives to address this issue by establishing an Integrated Structural Health Monitoring (ISHM) System for remote infrastructure sensing, diagnostics and prognosis. The ISHM entailed a few recent innovations that transformed the current state-of-the-practice in remote sensing and management of highway infrastructures.
