Instrumentation and Load Test of the Huey P. Long Bridge

摘要

For the Huey P. Long Bridge widening project, specifications were included in the construction documents to provide a truss monitoring system to compare actual versus predicted response of the bridge structure throughout the construction process. This paper describes the truss monitoring program for the Huey P. Long Bridge in New Orleans, consisting of measurement of existing eyebar forces through vibration methods, installation of an 850+ sensor array utilizing both static and dynamic systems, and load tests to calibrate the monitoring systems.
