This work will provide a structural "health" monitoring capability for Fiber-Reinforced Polymer (FRP) composite bridge decks. Three bridge decks are being built by an interdisciplinary team of the University of Missouri-Rolla (UMR) investigators to demonstrate the effectiveness of new FRP composite in enhancing constructability, life span, and performance. Each bridge deck will feature a different construction technology. They are being constructed in the City of St. James, Missouri using funds from the UMR, the City of St. James, and the Missouri Department of Economic Development. The construction contract has been awarded; hence, the funding need was immediate for adding "health" monitoring. Multiple fiber-optic strain sensors are being incorporated for long-term dynamic and static monitoring of performance and strength in this supplementary program which is being supported as a Small Grant for Exploratory Research (SGER).

这项工作将为纤维增强聚合物（FRP）复合材料桥面板提供结构“健康”监测能力。 密苏里大学罗拉分校（UMR）的一个跨学科研究小组正在建造三座桥面，以证明新型FRP复合材料在提高可施工性、寿命和性能方面的有效性。 每座桥梁都将采用不同的施工技术。 它们正在密苏里州的圣詹姆斯市建造，资金来自UMR、圣詹姆斯市和密苏里州经济发展部。 建筑合同已经签订;因此，立即需要资金来增加“健康”监测。 多个光纤应变传感器被纳入长期动态和静态监测的性能和强度在这个补充计划，这是支持作为探索性研究（SGER）的小额赠款。
