SGER: Monitoring Structural Damage in Complex Connections Using a Wave Vibration Approach

本研究提出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/梁处容易受到局部损伤。该调查解决了结构健康监测的正向和反向方法。考虑到(i)避免灾难性结构失效和（ii）不像传统方法那样昂贵、耗时且通常无效的问题和步骤。该研究计划反映了PI的长期目标，即开发创新的解决方法来解决实际工程问题，并培养广泛的学生。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进行客座演讲来接触K-12学生。通过密歇根大学迪尔伯恩分校的专业教育中心，还将开发网络演示和一门短期课程，向来自当地工业界的研究生、本科生和工程师提供。这是一个SGER项目。

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.
