摘要
时频联合分析方法因能同时提供信号的局部时频特征,适于分析非平稳信号而在土木工程领域得到了极大应用。线性变换、双线性变换和Hilbert-Huang变换是土木工程中常用的时频联合分析方法。根据时频分析方法的理论,将其应用于人工地震波模拟、结构动力反应分析和可靠性估计、结构参数识别及损伤检测等领域。通过对其在土木工程中的应用进行总结,提出了存在的问题,探讨了进一步研究的方向。
The methods of joint time frequency analysis have been widely applied in civil engineering due to its ability to provide local time frequency characteristics of signal and the ability to analyze nonstationary signal. Linear transform, bi linear transform and Hilbert Huang transform have been applied in the simulation of artificial seismic wave, dynamic analysis and estimation of the reliability of structures, parameters identification and damage detection in civil engineering. The existing problems are presented and the further research direction is discussed based on the summation of the application of the methods in civil engineering.
