Abstract

A comprehensive structural health monitoring (SHM) system has been implemented on the Tacony-Palmyra Bridge in Philadelphia, Pennsylvania (USA). The Tacony-Palmyra Bridge is an over 80 year old structure that includes a two-leaf, rolling lift, bascule system (79m span). The health monitoring system was developed using the structural identification process along with a historic review and vulnerability assessment. The underlying objective of the project is to indefinitely preserve the structure by leveraging modern technology. As a result, the primary focus has been placed on addressing engineering, operation, and maintenance needs of the bridge. This was executed with the use of distributed data acquisition systems. The instrumentation includes electrical resistance and vibrating wire strain gages, tilt sensors, and a weather station. Cameras were also placed at selected locations on and around the structure. The integration of data and video was accomplished through the development of a live web portal and a customized playback program. The live web portal allows for real-time remote viewing of the data and video over the internet. The structural monitoring software includes the ability to record events such as bascule openings and overloaded vehicle passage. These events can be viewed in the playback program. This program allows the data to be viewed both spatially and temporally so as to maximize data interpretation and benefit for the end user of the SHM. The system is also equipped with trigger and alert functionality for specified events. The goal is to provide the bridge owner with an effective and reliable decision making tool to better manage their structure.
