Structural Health Monitoring for the Tacony-Palmyra Bridge

Structural Health Monitoring for the Tacony-Palmyra Bridge

Design and installation of an efficient structural health monitoring (SHM) system capable of providing information regarding the operational and structural performance of the Tacony-Palmyra Bridge. The owner, Burlington County Bridge Commission, has adopted the goal of indefinite preservation for their signature structures and has moved to augment conventional engineering practices with the latest sensing and simulation technology to ensure all decisions are made from the most informed standpoint possible. The Tacony-Palmyra Bridge is a signature long-span bridge that crosses the Delaware River connecting Tacony, Pennsylvania, and Palmyra, New Jersey. The bridge is nearly a mile long and includes a 550-foot steel tied arch span and a 260-foot bascule span.

The SHM system was driven by a comprehensive risk assessment and implemented using the best practices structural identification approach. To date, the primary focus of the system has been placed on addressing operational and maintenance needs and providing quantitative data related to the most critical structural performances.
