摘要
近年来,随着传感技术、信号采集与处理等技术的发展,土木结构的损伤识别研究已经提出了很多方法.然而,将这些方法应用于实际工程中遇到了很多困难.基于近20年来国内外基于振动信息损伤识别的研究和应用现状;重点讨论结构损伤识别方法在土木工程应用中面临的挑战,并系统地综述了为解决这些问题而提出的一些方法;对有待于进一步研究的问题进行了展望.
With the development of sensor, signal acquiring and processing technologies, a＇ largernumber of vibration- based damage detection methods have been proposed for civil engineering structures in recent years. However, we have difficulties in applying these methods to real structures in operating environments. After a brief introduction to the vibration - based damage detection methods developed over the last 20 years and their applications, this paper presents an analysis of the primary challenges in applying these damage detection methods, and provides an overview of the associated solutions. It concludes with a discussion of critical issues for future research in the area of vibration - based damage detection.
