Health Monitoring of FRP Composite Bridge Decks

这项工作将为纤维增强聚合物（FRP）复合桥面提供结构“健康”监测能力。密苏里大学罗拉分校（UMR）研究人员组成的跨学科团队正在建造三座桥面，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。每个桥面都将采用不同的施工技术。他们正在密苏里州的圣詹姆斯市建造，使用UMR，圣詹姆斯市和密苏里州经济发展部的资金。施工合同已中标；因此，增加“健康”监测的资金需求迫在眉睫。在这个补充项目中，多个光纤应变传感器被用于长期动态和静态监测性能和强度，该项目得到了探索性研究（SGER）小额赠款的支持。

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).
