Web‐Based Structural Health Monitoring of an FRP Composite Bridge
Abstract: To develop an understanding of the long‐term performance of fiber reinforced polymer (FRP) composite bridge structures, a health monitoring scheme utilizing wireless technology was implemented on the Kings Stormwater Channel Bridge. The bridge, which is located on a major state highway in California, utilizes FRP composite girders and deck panels. The data collected by a comprehensive array of sensors are transmitted wirelessly, and processed in real‐time remotely. Computer‐based automated analysis algorithms process the incoming data to provide an assessment of structural response. Effects, due to time‐based deterioration, and irregularities are determined using modal parameters, in terms of damage localization indices and an estimated damage severity. The results, made available via a web‐based interface, enable appropriate action to be authorized for preliminary maintenance or emergency response prior to actual on‐site inspection. It is expected that such systems will not only give engineers a valuable tool in monitoring the structural performance of critical bridge systems, but will also provide important information related to durability, design criteria, and long‐term response of FRP composite structures.
