基于不确定性的结构损伤识别方法研究综述

基于静动力特性改变的结构损伤诊断方法在过去几十年中发展迅速。与损伤识别的确定性方法相比,损伤识别的不确定性方法能更为有效合理地处理损伤识别过程中涉及的不确定性干扰问题,并从统计意义上实现复杂工程结构健康监测的早期损伤诊断,因此已成为当前结构损伤识别领域的研究热点。在简要回顾了损伤识别确定性方法的基础上,主要介绍了损伤识别不确定性方法的研究进展,并分析了各方法的优缺点,对有待进一步研究的问题及此类方法的发展趋势进行了展望。

A REVIEW OF STRUCTURAL DAMAGE IDENTIFICATION METHODS BASED ON UNCERTAINTY

Based on changes of static and dynamic structural characteristics,the damage identification methods have developed rapidly in the past few decades.Compared with the deterministic damage identification method,the damage identification uncertainty method can more effectively and reasonably deal with the uncertainty interference problem in the process of damage identification,and realize the early damage identification of health monitoring of complex engineering structures from the statistical significance,therefore has become the hot research topic in the field of structural damage identification.On the basis of briefly reviewing the deterministic methods of structural damage identification,this paper mainly introduces the research progress of uncertain damage identification methods,their advantages and shortcomings of these damage identification methods are analyzed.Topics worthy of further study and the development trend of such methods are presented.
