摘要

工程结构的损伤识别问题是目前的研究热点,近年来已提出许多种损伤识别方法。其中,柔度方法因计算简单实用性强而倍受人们关注。本文综述了近二十年来基于柔度变化的结构损伤识别方法,按照计算方法和采用数据的不同将柔度方法进行了分类和归纳,阐述了各类柔度方法的基本原理和主要的计算公式,并分析和比较了各类柔度方法的优点和不足之处。最后讨论了柔度方法尚存的未解决难题并对后继研究方向作了展望。

Abstract

Structural damage identification using measured static or dynamic data has emerged as a new research area in civil, mechanical and aerospace engineering communities. A large number of approaches have been proposed for detecting structural damage in recent years. In these existing approaches, the flexibility-based method is one of the promising techniques since the flexibility can be constructed easily from the measured static or lower frequency modes and is very sensitive to structural damage. This paper presents a general summary and review of the flexibility-based damage identification methods in the past two decades. These flexibility-based techniques can be divided into six groups by the different calculation methods and data used. The basic idea of each group is briefly illustrated and the main formulas are given, respectively. The advantages and shortcomings of these approaches are also discussed and compared in detail. In the end, several key issues related to flexibility-based damage identification methods are emphasized and future study aspects are pointed out.
