报告摘要：

Aging and unforeseen events cause civil infrastructure to deteriorate during service life. Accurate understanding of risks due to the deterioration and how the risks evolve over time is essential to making informed decisions for sustainable operation and maintenance. To this end, acquiring critical in-situ data that depicts accurately how structures deteriorate at both local and global scales becomes imperative. This presentation explores recent development in structural health monitoring, inspection, and control using both traditional and emerging sensing techniques for buildings, high-mast illumination poles (HMIP), bridges, and concrete dams. Key topics include optimal virtual sensing strategies for dynamic systems in the absence of input information, field monitoring to unveil wind-induced vibration mechanisms in HMIPs and mitigation strategies, and wireless skin sensor network for continuous fatigue crack monitoring. In addition, a variety of advanced computer vision, artificial intelligence, and augmented reality techniques will be presented for inspection of steel bridges and concrete dams. These developed monitoring and control methodologies play an important role in effective risk management and mitigation of critical infrastructures.

老化和不可预见的事件会导致民用基础设施在使用寿命期间出现老化。准确了解老化造成的风险以及风险如何随时间演变，对于做出可持续运营和维护的明智决策至关重要。为此，当务之急是获取关键的原位数据，准确描述结构在局部和全球范围内的老化情况。本讲座将探讨利用传统和新兴传感技术对建筑物、高杆照明灯杆（HMIP）、桥梁和混凝土大坝进行结构健康监测、检测和控制的最新进展。主要议题包括在没有输入信息的情况下动态系统的最佳虚拟传感策略、揭示高杆照明灯杆风致振动机理的现场监测和缓解策略，以及用于连续疲劳裂缝监测的无线表皮传感器网络。此外，还将介绍各种先进的计算机视觉、人工智能和增强现实技术，用于检测钢结构桥梁和混凝土大坝。这些开发的监测和控制方法在关键基础设施的有效风险管理和缓解方面发挥着重要作用。
