2. ANCRiSST 2011 Workshop 2/7 Structural Health Monitoring Working Group Discussion Summary ANCRiSST 2011 Conference: Dalian, China – July 26, 2011 1. Smart Sensors & Sensing Technologies  Do we need to develop or improve upon current smart sensing technologies?  Yes, visual inspection still remains the current state-of-art  Several different categories where sensor development is needed:  Optical-based sensors or vision-based sensing  Include fusing fiber optic sensing with wireless capabilities  New materials and multifunctional materials  Multiple engineering functionalities: multi-modal sensing, energy scavenging, environmental monitoring, and actuation/interrogation, among others  Self-diagnosing and self-healing materials  European Union and select research groups (HIT, DLUT, UM) are very active  Need systems-approach for self-healing and self-diagnosis  Robotic sensing and associated infrastructure  Not only useful for SHM but also for security and gathering various information  Bio-inspired sensing still in its infancy  Chemical sensors for corrosion  Sensors for challenging environments  Deep-sea offshore oil platforms, wind turbines, built environment, etc.  Use of many not-so-smart or ordinary sensors for densely-distributed sensing

3. ANCRiSST 2011 Workshop 3/7 Structural Health Monitoring Working Group Discussion Summary ANCRiSST 2011 Conference: Dalian, China – July 26, 2011 2. Data Informatics and Data Mining  What information do we need to sense and how do we process the data?  Need new methodology for dealing with different types of sensors and data  Current research still dominated by vibration-based monitoring  Data fusion problem: global v. local and different types of sensor data  Issue of monitoring all members/locations v. critical locations/”hot spots”  Objective is to detect damage severity and location  Probability of Detection (POD): civil engineers need to start quantifying POD  Ex: how big of a crack can you detect, and what is the probability of detecting it?  Bio-informatics modeling and data modeling  Bio-inspired data interpretation and data mining  Biological creatures can autonomously differentiate between the variety of data collected  Spooling: fish can extract basic information from many neurons for decision making  Machine-learning and data-mining methods for analyzing large data sets  Imitate how doctors or professionals diagnose humans  Access to existing monitoring data or benchmark models  Prof. Li has collected information from damaged bridge structure and will make public  Jindo bridge monitoring data will potentially be made to the public late this year  Hong Kong Polytechnic University Guang Zhou TV Tower monitoring data on web  Talk to ANCRiSST

4. ANCRiSST 2011 Workshop 4/7 Structural Health Monitoring Working Group Discussion Summary ANCRiSST 2011 Conference: Dalian, China – July 26, 2011 3. Integrating SHM with Current Methods  How does one integrate SHM with current methods?  Life cycle cost and life cycle assessment  Need to integrate SHM with life cycle cost and assessment to achieve desired life cycle performance  Build resilient infrastructure while extending their service life  How will climate change affect civil infrastructure  Need collaboration across disciplines and research groups  Reliability-based SHM  Most cases, deterioration is gradual (fatigue, corrosion, loading, etc.)  Find probability of failure and predict remaining service life and cost of maintenance  Useful for future code development  Risk management  We know what vibration means, but the general public may not  Need ways of communicating to the general public for emergency management  Autonomous decision making strategies and communication systems (tsunami)  Accurate information is critical  Appropriate business models for each particular industry  Understand the needs of owners, government agencies, and stakeholders  Successful example is dams where it is heavily regulated with SHM

5. ANCRiSST 2011 Workshop 5/7 Structural Health Monitoring Working Group Discussion Summary ANCRiSST 2011 Conference: Dalian, China – July 26, 2011 4. Education  Structural health monitoring is a multi-disciplinary field of study  Some students may only focus on one small aspect of SHM  Is the current engineering curricula adequate for training our future students  Need online learning or e-learning approaches  Sharing of SHM course content and teaching materials  Asian-Pacific Summer School (APSS) on Smart Structures Technologies  Course contents and all teaching materials from previous years available online  After 6 APSS summer schools, a group of researchers will get together to write a textbook
