LONG-TERM REMOTE MONITORING OF PROTOTYPE ORTHOTROPIC DECK PANELS ON THE BRONX WHITESTONE BRIDGE FOR FATIGUE EVALUATION

As part of a comprehensive fatigue evaluation of the replacement orthotropic bridge deck on the Bronx Whitestone Bridge in New York City, an in-depth field instrumentation, testing, and monitoring program has been developed and implemented on a 2-span prototype orthotropic deck panel located in the main suspended span. The data will be used to validate the lab fatigue testing program and establish in situ stress-range histograms at critical details. Controlled load testing was completed and uncontrolled remote monitoring is currently underway. The remote monitoring system utilizes an innovative application of traditional data acquisition coupled with recorded video to accurately establish the type, configuration, and position of trucks producing large stress ranges. This paper focuses on the unique approach to data acquisition and monitoring report, and briefly summarizes the initial results of the monitoring.
