In this research, a vibration-based structural health monitoring methodology for complex structures vulnerable to localized damage at inaccessible structural joints/girders is developed. The investigation addresses both the forward and inverse approaches for structural health monitoring. Issues and steps to (i) avoid catastrophic structural failures and (ii) be not expensive, time consuming, and often ineffective as for conventional methods are taken into consideration. The research plan reflects the PI's long-term goal of developing innovative solution methods to solve practical engineering problems and educate a broad spectrum of students. This research allows the direct participation of both graduate and undergraduate students. The PI will reach K-12 students by guest speaking in local schools' science and technology curriculum activities. Web-based demonstrations and a short course will also be developed to offer to graduate students, undergraduate students and engineers from local industry through the Professional Educational Center of the University of Michigan-Dearborn.This is a SGER project.

在这项研究中，发展了一种基于振动的结构健康监测方法，用于复杂结构在不可接近的结构节点/大梁处易受局部损伤的情况。这项调查涉及结构健康监测的正反两种方法。考虑到(I)避免灾难性结构故障和(Ii)不像传统方法那样昂贵、耗时且往往无效的问题和步骤。该研究计划反映了PI开发创新解决方法以解决实际工程问题并教育广泛学生的长期目标。这项研究允许研究生和本科生直接参与。PI将通过在当地学校的科学和技术课程活动中客座演讲的方式接触到K-12学生。还将开发基于网络的演示和短期课程，通过密歇根大学迪尔伯恩分校的专业教育中心向来自当地行业的研究生、本科生和工程师提供服务。
