Non-contact Air-coupled Sensing for Rapid Evaluation of Bridge Decks

Present:  March 12, 2020, 11:00 AM Central Time
Speaker: Dr. Jinying Zhu, University of Nebraska-Lincoln



Elastic wave-based non-destructive testing (NDT) methods are commonly used for evaluation of civil engineering infrastructure, including bridges, dams and buildings. However, most of these methods require coupling (direct contact) between sensors and the test surface, which significantly restricts the testing speed and consistency, especially for large scale concrete structures in civil engineering. The air-coupled sensing technology was developed by Dr. Jinying Zhu as a solution for rapid scanning of concrete infrastructure. In this webinar, Dr. Zhu will review the development of air-coupled sensing technique for civil engineering applications, including fundamental theory and field application of air-coupled sensing on concrete structures. She will also present a recently developed automated acoustic scanning system for quick bridge deck evaluation and imaging.


Dr. Jinying Zhu is an associate professor in Department of Civil Engineering at the University of Nebraska Lincoln. She received her Ph.D. degree in civil Engineering from the University of Illinois at Urbana-Champaign in 2006. Her research interests include NDT for concrete, wave propagation, cement material characterization using ultrasonic waves, and innovative sensing techniques. Dr. Zhu is a recipient of the ASNT Fellowship Award in 2012, and four times winner of ACI-James Instruments Award. She is an associate editor of Journal of Nondestructive Evaluation.
