State-of-the-Field: Application of Structural Health Monitoring (SHM) and Weigh-In-Motion (WIM) Sensors For Infrastructure Assessment and Resiliency

November 23, 2021 @ 12:00 pm - 1:00 pm

Structural Health Monitoring (SHM) is being applied to many types of infrastructure to determine its durability, performance and response to various loading conditions. Weigh-In-Motion (WIM) provides an efficient way to estimate the static weight of a vehicle by measuring the dynamic tire force of a moving vehicle. Recently, emphasis has been placed on coupling these two complementary technologies in infrastructure evaluation and resiliency: SHM provides structural response or resistance while WIM provides actual loading conditions and future load prediction that enables determination of infrastructure capacity, resulting in the operating service loads needed for developing statistical live load models for use at the strength and service limit states.

Dr. Nassif will provide an overview of how SHM, WIM, and related sensor technologies have evolved over the last three decades, emphasizing the current SHM programs of civil infrastructure in the NY/NJ Metropolitan Area. He’ll discuss various projects highlighting structural modeling and analysis, sensor networking and instrumentation, data processing, model validation, and probabilistic predictions. Dr. Nassif will also provide an overview of how various sensor data might be processed to assess actual behavior of the structure at various stages, and how unique solutions adopted in response to various agencies’ design and construction issues have led to major improvements in model predictions, calibration of reliability-based design codes, and successful implementation and modifications of technical specifications.


Dr. Nassif is a Professor in the Department of Civil and Environmental Engineering and Director of the Rutgers Infrastructure Monitoring and Evaluation (RIME) Group at Rutgers University, where he has established the Bridge Engineering program. He is also serving the Associate Director for Outreach and Technology Transfer at the federally-supported C2SMART Tier 1 University Transportation Center (UTC) at which Dr. Nassif is leading the significant efforts to conduct the research area of the resilient, secure, and smart transportation infrastructure.
