摘要
简要介绍了一维小波分析的基本原理和分类,及其在土木工程领域的主要应用。重点论述了小波变换在结构损伤检测方面的应用。由小波分析的数据中提取人工神经网络的训练样本能够更好的反应结构缺损特征,故小波分析或以小波分析为基础的人工神经网络方法是结构损伤识别的一种很有前途的方法。
The basic theory, classification and its application in civil engineering of the one-dimensional wavelet analysis are briefly introduced in this paper. The successful application of the wavelet analysis in structural damage detection is emphasized. The damage features of the time domain response signal are more obvious after being wavelet transformed. The wavelet-based approach or the wavelet neural network is a promising method in the structural damage identification.
