The objective of this Faculty Early Career Development (CAREER) Program award is to establish a long-term research and educational program which focuses on the application of mobile sensors for structural health condition assessment. The inclusion of sensing capabilities in mobile devices presents an incredible opportunity for measuring structural response and environmental conditions at rates, volumes and locations not possible in the past. This project will develop the analytical models and experimental platform for validation and verification that will improve safety and reliability of highway bridges. The project aims to produce knowledge and build the foundation necessary for taking advantage of a wealth of data that will become available through mobile sensors for structural monitoring. The ultimate objective of this project is to use this abundant data for structural condition assessment that will benefit the society. The project will incorporate its research products into a comprehensive educational plan for underclassmen, underrepresented and community college students, through two specific programs: a hands-on Summer School in Sensing and Structural Health Monitoring, and Project Based Research at the institution for Community Colleges.The project aims to produce and manage the knowledge, and build the foundation necessary for taking advantage of a wealth of data that will become available through mobile sensors for structural monitoring. It will test the hypotheses that (i) the dynamic properties of a bridge can be identified using data from moving sensors which produce randomly incomplete data matrices, (ii) dynamic interaction of a vehicle carrying mobile sensors over a bridge can be exactly or approximately uncoupled from the motions of the bridge, and (iii) a prototype test bed could produce data and procedures to verify the validity of the estimated dynamic properties of a bridge using mobile sensors. Testing these hypotheses is crucial in addressing the technology and data processing knowledge gaps for using mobile sensors for monitoring structures. An entire class of new methods for understanding the behavior of systems is developed; they form a unique platform that uses mobile devices to understand the performance of infrastructure systems.

这个教师早期职业发展（CAREER）计划奖的目标是建立一个长期的研究和教育计划，重点是移动的传感器的结构健康状况评估的应用。在移动的设备中包含传感功能，为以过去不可能的速率、体积和位置测量结构响应和环境条件提供了令人难以置信的机会。本项目将开发分析模型和实验平台，用于验证和验证，以提高公路桥梁的安全性和可靠性。该项目旨在产生知识并为利用将通过移动的传感器获得的大量数据进行结构监测奠定必要的基础。本项目的最终目标是利用这些丰富的数据进行结构状态评估，造福社会。 该项目将通过两个具体方案，将其研究成果纳入为低年级、代表性不足和社区大学学生制定的综合教育计划：一个在社区学院的传感和结构健康监测的实践暑期学校，以及基于项目的研究。该项目旨在产生和管理知识，并为充分利用通过移动的传感器获得的大量数据进行结构监测奠定必要的基础。它将检验以下假设：（i）桥梁的动态特性可以使用来自移动传感器的数据来识别，这些数据产生随机不完整的数据矩阵，（ii）携带移动的传感器的车辆在桥梁上的动态相互作用可以与桥梁的运动完全或近似解耦，以及（iii）原型试验台可以产生数据和程序，以验证使用移动的传感器的桥梁的估计动态特性的有效性。测试这些假设对于解决使用移动的传感器监测结构的技术和数据处理知识差距至关重要。开发了一整套用于理解系统行为的新方法;它们形成了一个独特的平台，使用移动的设备来理解基础设施系统的性能。
