Instrumentation Performance During Long-Term Bridge Monitoring

Robertson, Ian N. / Johnson, Gaur P. / Wang, Shujun

Abstract This paper reviews the performance of a variety of instruments installed in the North Halawa Valley Viaduct for a 10-year monitoring program. Over 200 electrical strain, displacement, temperature and load sensors were installed during construction of the long-span box-girder viaduct on the island of Oahu in 1994. These instruments have been monitored continuously since installation. Comparisons are presented where two types of sensor were used to monitor the same response. Each of the instrumentation systems is evaluated for its performance in monitoring short-term and long-term response. Advantages and disadvantages are presented for each type of sensor used in this project.
