| 摘 要： | 对工程结构进行损伤识别与检测,可以发现结构损伤位置,评估损伤程度,为结构加固与修复提供依据,从而保证工程结构正常运行,进而保护人们生命财产安全,因此结构损伤识别方法研究一直是土木工程领域重要研究课题。结构损伤识别方法总体上分为确定性方法和不确定性方法,相比于确定性方法,不确定性方法考虑了识别过程中不确定因素的影响,成为目前损伤识别领域的研究热点。本文回顾了确定性方法和不确定性方法发展历程,阐述了几种常见的损伤识别方法及其优缺点,并根据国内外研究现状对结构损伤识别方法发展进行了展望,可供损伤识别方法研究与应用参考。

| Abstract: | The damage identification of engineering structures can detect the location of the damage, evaluate the damage level and provide the basis for structural reinforcement and repair. The target is to ensure the normal operation of engineering structures and protect the safety of people’s lives and property. Therefore, the structural damage identification methods have always been a significant research topic in the field of civil engineering. The structural damage identification methods are generally divided into deterministic methods and nondeterministic ones. Compared with the deterministic identification methods, the nondeterministic methods become a research focus in the field of structural damage identification because of considering the influence of uncertainties. In this paper, the development of deterministic methods and nondeterministic ones are reviewed briefly, and several common methods of structural damage identification are expounded. Their advantages and disadvantages are pointed out, and the future study of structural damage identification is proposed according to the state-of-the-arts of relative studies. It can be referred as a reference for the research and application of damage identification methods. |
