| 摘 要： | 小波变换具有良好的时频局部化性质,特别适合于分析和处理突变信号。在获得结构的动力学响应的基础上,应用小波变换对结构响应信号进行小波分解。根据各种响应信号对损伤的灵敏度,选择损伤特征,通过捕捉结构出现损伤的时刻,实现对结构时间监控。

| Abstract: | wavelet transform has the good property of time-frequency localization,which is especially fit for analyzing and processing the singular signal.The main subject is calculating the dynamic response of shear type construction.Then the structure response signal is decomposed with wavelet tools after denoising.The damage character is chosen by comparing the susceptibility to damage among every response signal,the real-time monitoring for shear type construction is realized by catching the damaging moment. |

| Keywords: | dynamical response wavelet transform time monitoring |
