Smart Installation and Monitoring System for Large Anchor Bolts of Support Structures Made with 3D Printing Enhancement

Anchor bolts, as a connection system used at the base of most highway support structures, commonly suffer from loosening effects that may impose high risk on collapse for the structures.

The TRB IDEA (Innovations Deserving Exploratory Analysis) Program's NCHRP IDEA Final Report for Project 196: Smart Installation and Monitoring System for Large Anchor Bolts of Support Structures Made with 3D Printing Enhancement aims to develop a capacitance-based smart washer system that serves as an efficient way to monitor the tension inside the anchor bolts before the loose anchor bolts can cause severe stability issues.
