摘要 土木工程结构具有尺寸大、质量重、自振频率和振动水平较低等特点,其动力响应极容易受到不可预见的环境状态、非结构构件等的影响,这使得结构的健康监测和损伤诊断具有极大的挑战性,是近年来国际上研究的热点。本文综述了土木工程结构损伤诊断方法的最新进展,内容包括动力参数诊断方法、静力参数诊断方法、子结构方法、统计分析方法、神经网络方法等,同时简要介绍了与损伤诊断有关的系统识别与模型修正以及传感器优化布置等的研究进展,最后展望了结构损伤诊断的研究和发展方向。 Recent advances in research on structural damage diagnosis are reviewed in the paper. It is a challenging task to diagnose the structural damage for civil engineering. Many ways of the diagnosis are discussed in detail. It is found that the model updating, the system identification, and the sensors layout are important topics too. It is confirmed that the diagnosis has a good prospect in civil engineering. However, there yet some works are needed to be done in the future.
