Smart infrastructure applications have used distributed fiber optic sensors to monitor strain, vibration, and temperature. IEEE standards exist for Bragg grating sensors and distributed acoustic sensors (DAS). The current standard activity will expand the monitoring capability to include overloading bridge capacity with heavy vehicles, the impact of corrosion, crack formation, and growth in structural members. The purpose is to monitor structural health by changes in monitored parameters (including strain and vibration signature) and identify potential points of failure. While the impact of corrosion and cracked structures will be monitored, the scope of the activity does not include characterization of the fracture mechanics of the crack formation or chemistry associated with corrosion, which typically requires a laboratory environment. In addition, the standard activity will address how these sensing systems interface with both wired and wireless local area networks and power remote sensing systems. Monitored infrastructure includes bridges, tunnels, dams, buildings, rail lines, power lines, and pipelines.

Working Group Details
Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
