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

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.
