Structural Health Monitoring (SHM) is a range of technologies that spans sensors, data collection, data storage and communication for tracking, presentation, and interpretation of live structural performance data. For civil structures (e.g. bridges, buildings, dams etc.) SHM is intended to provide structure operators and owners with the essential information they need to manage the maintenance, safety and operation of their structures effectively and efficiently. SHM is a rapidly growing international research discipline driven by the recognition in developed countries that priorities are switching from construction to maintenance and upgrading of infrastructure. There are clear indications of the need for an potential of SHM systems to assist infrastructure operators with information for decision making, but so far success stories in structural engineering are rare. In paticular in the UK, SHM has had a lack-lustre track record, due to past overselling and unrealistic exepctations. Experience in other applications, such as mechanical engineering has been more promising and there are now working technologies available, many of which rely on sophisticated interpretation of response data, or 'data mining'. This project focusses on the interpretive end of SHM with technology transfer from successful applications in mechanical engineering.Hence, the proposal aims to develop a leading edge capability in SHM of civil infrastructure at the University of Sheffield. It capitalises on key ingredients for success which are:-The experience of Professor Brownjohn in civil structure SHM gained through designing and operating several full-scale structural monitoring systems in UK and Singapore over the last twenty years-The expertise of Professor Worden in SHM applications to aerospace structures which have earned him international recognition-Access to a number of major structures in the UK and in overseas where there is a demonstrated need for application of SHM technology and-The strong research environment that supports a range of activities relating to full-scale structural performance.With access to structures such as Tamar and Humber suspension bridges in the UK and Fatih Bridge in Turkey, instrumentation systems will be created from scratch, upgraded or accessed to provide, in real-time, information about performance of these structures that can be related to numerical models calibrated by dynamic testing. The aim is to provide a real-time capability for diagnosis of key aspects of structural performance.

结构健康监测（SHM）是一系列技术，涵盖传感器，数据收集，数据存储和通信，用于跟踪，呈现和解释实时结构性能数据。用于土木结构（例如桥梁、建筑物、水坝等）SHM旨在为结构运营商和业主提供有效管理其结构的维护，安全和运营所需的基本信息。SHM是一个快速发展的国际研究学科，其发展是由于发达国家认识到优先事项正在从基础设施的建设转向维护和升级。有明确的迹象表明，需要SHM系统的潜力，以协助基础设施运营商的决策信息，但到目前为止，在结构工程的成功案例是罕见的。特别是在英国，由于过去的过度销售和不切实际的期望，SHM的业绩记录乏善可陈。在其他应用方面的经验，如机械工程，一直更有前途，现在有可用的工作技术，其中许多依赖于响应数据的复杂解释，或“数据挖掘”。该项目的重点是通过机械工程中成功应用的技术转移来解释SHM。因此，该提案旨在发展谢菲尔德大学在民用基础设施SHM方面的领先能力。它利用成功的关键要素，这些要素是：- Brownjohn教授在土木结构SHM方面的经验，在过去的二十年里，他在英国和新加坡设计和操作了几个全尺寸结构监测系统;-沃登教授在SHM应用于航空航天结构方面的专业知识，使他获得了国际荣誉;-可以接触英国和海外的一些主要结构，这些结构对SHM技术的应用有明显的需求;-强大的研究环境，支持与全尺寸结构监测系统有关的一系列活动;规模结构性能。随着英国添马舰和亨伯吊桥以及土耳其塔霍河大桥等结构的使用，将从头开始创建、升级或访问仪表系统，实时地，关于这些结构的性能的信息可以与通过动态测试校准的数值模型相关。其目的是为结构性能的关键方面提供实时诊断能力。
