项目摘要
A large part of our infrastructure was built in mid-seventies and they are in urgent need of rehabilitation and/or reconstruction. In order to reduce the vulnerability of structures to operational and extreme loadings (e.g., earthquake), it is important to determine their structural conditions and capacity through regular inspection and Structural Health Monitoring (SHM) techniques. This is essential for making effective decisions on structural rehabilitation, and take advantage of high performing materials (e.g., high strength concrete, fiber reinforced polymer or FRP), and new devices and systems (e.g., dampers and control systems) to improve the structural performance and resilience.The long term goal of the proposed research is to develop effective methods to achieve sustainable and resilient infrastructure. The short term goals are to: (1) develop innovative SHM techniques for evaluation of the in-situ performance of structures, and (2) develop practical methods to improve structural performance and resilience to operational and extreme events (e.g. earthquake) using the SHM-based condition assessment.To achieve Goal 1, the proposed research program will focus on the development of new sensing methods for monitoring, system identification and damage detection techniques in structures. Particular attention will be given to wireless sensors for SHM and their performance will be studied in the laboratory and field. A number of issues including optimal placement of sensors, appropriate deployment mechanism, detecting sensor malfunction, environmental effect on monitoring data, detecting novel events (e.g., earthquake), identify system properties, and detect structural damage will be addressed in this research.To achieve Goal 2, the present research will focus on new materials and technologies such as advanced composites and damping devices to upgrade the performance of a structure. Particular attention will be given to magneto-rheological (MR) fluid-based semi-active dampers in controlling vibration response in structures. Effective application of these devices requires simplified methods to model them in a structural system, which will be addressed here by developing a simplified modelling technique for such devices and integrating them to structural models to analyze their performance. The functioning of a semi-active device can be directly tied to the SHM system of a structure as such a device requires feedback from structure in terms of its dynamic response.The proposed research program will be built upon the applicant's ongoing work in the above areas. There is significant potential for innovation in the proposed research which aims at enhancing the fundamental knowledge in the above areas. The outcome of the research is expected to enhance the safety of the civil and built infrastructure and benefit the Canadian society.
我们的很大一部分基础设施是在七十年代中期建造的,它们迫切需要恢复和/或重建。为了减少结构在运行和极端荷载(如地震)下的脆弱性,必须通过定期检查和结构健康监测(SHM)技术来确定其结构状况和能力。这对于做出有效的结构修复决策是至关重要的,并利用高性能材料(例如高强混凝土、纤维增强聚合物或FRP)以及新的设备和系统(例如阻尼器和控制系统)来提高结构的性能和弹性。拟议研究的长期目标是开发有效的方法来实现可持续和弹性的基础设施。短期目标是:(1)开发创新的结构健康监测技术,用于现场评估结构的性能;(2)开发实用的方法,利用基于健康监测的状态评估来提高结构性能和对操作和极端事件(如地震)的恢复能力。为了实现目标1,拟议的研究计划将集中于开发新的监测、系统识别和结构损伤检测技术的传感方法。将特别关注用于SHM的无线传感器,并将在实验室和现场研究其性能。这项研究将涉及传感器的最优布置、合适的部署机制、检测传感器故障、环境对监测数据的影响、检测新事件(例如地震)、识别系统特性和检测结构损伤等问题。为了实现目标2,本研究将专注于新材料和新技术,如先进复合材料和减震装置,以提升结构的性能。磁流变(MR)半主动阻尼器在控制结构振动响应方面将受到特别关注。这些设备的有效应用需要简化的方法来在结构系统中对其进行建模,这里将通过开发此类设备的简化建模技术并将其集成到结构模型中来分析其性能来解决这一问题。半主动装置的功能可以直接与结构的减振系统捆绑在一起,因为这种装置需要结构在其动态响应方面的反馈。拟议的研究计划将建立在申请人在上述领域的持续工作基础上。拟议的研究具有很大的创新潜力,其目的是加强上述领域的基础知识。预计研究结果将提高民用和已建基础设施的安全性,并使加拿大社会受益。
