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

在这项研究中，基于振动的结构健康监测方法的复杂结构容易局部损伤的不可访问的结构节点/梁。调查解决了结构健康监测的正向和反向方法。问题和步骤，以（i）避免灾难性的结构故障和（ii）是不昂贵的，耗时的，往往是无效的，因为传统的方法被考虑在内。该研究计划反映了PI的长期目标，即开发创新的解决方案，以解决实际工程问题，并教育广泛的学生。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客座演讲来接触K-12学生。此外，还将通过迪尔伯恩大学的专业教育中心，为当地工业界的研究生、本科生和工程师开发基于网络的演示和短期课程。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.
