Abstract

The nation's civil transportation infrastructure of structural concrete bridges is aging and deteriorating - principally as a result of the corrosion of the steel reinforcement that gives these structures their tensile strength. The primary objective of our research is to develop a cost-effective wireless embedded sensor system that detects the onset of corrosion and directly relates the sensor data to the deterioration of the girder's structural performance characteristics. Reaching this objective requires our multidisciplinary team to integrate the following three research thrusts: (1) non-destructive evaluation (NDE) of reinforcing tendons; (2) embedded wireless sensors; (3) diagnostic tool development that relates sensor data to changes in structural performance characteristics. In cooperation with the Illinois Department of Transportation, the research project will culminate with a field demonstration of the embedded sensor system installed in a prestressed girder.

一个跨学科的努力，开发无线嵌入式传感器系统，以监测和评估预应力混凝土梁的肌腱腐蚀

国家的民用交通基础设施结构的混凝土桥梁老化和恶化-主要是由于腐蚀的钢筋，使这些结构的抗拉强度。我们研究的主要目标是开发一种具有成本效益的无线嵌入式传感器系统，该系统可以检测腐蚀的发生，并直接将传感器数据与梁的结构性能特征的恶化联系起来。实现这一目标需要我们的多学科团队整合以下三个研究重点:(1)加强肌腱的非破坏性评估(NDE);(2)嵌入式无线传感器;(3)将传感器数据与结构性能特征变化联系起来的诊断工具开发。在与伊利诺斯州交通部的合作下，该研究项目将在安装在预应力梁上的嵌入式传感器系统的现场演示中达到高潮。
