Structural health monitoring involves continuously measuring key structural and environmental parameters in real time to detect damage to structures, provide maintenance advice, and improve safety. It aims to enhance safety beyond traditional design approaches that rely on overdesign, damage tolerance principles, quality control, and periodic inspections. Structural health monitoring could help prevent disasters caused by undetected structural failures, even for structures designed with robust safety factors and inspection protocols.

- 1. Definition: In-service evaluation of structural health status by measuring key structural and environmental parameters on a continuous base at real time. Purposes of SHM: Detect structure damages •Strength of constituent materials •Safety, Safety, Safety • Provide maintenance and rehabilitation advices • Improve design guidelines • Disaster mitigation What is Structural Health Monitoring?
- 2. Current Safety Assurance Practices • Design with large safety factors-overdesign • Design for damage tolerance – Life prediction (material damage, fracture mechanics) – Quality control (material processing, manufacturing, assembly) – Accurate specification of operational conditions • Periodic Inspection – Manual – Nondestructive Evaluation (visual, ultrasound)
- 3. Infamous Disasters due to Structural Failures Question: If all structures are designed properly, do we still need Structural Health Monitoring?
