基于小波变换的桥梁损伤识别研究

Study on methods of damage identification of bridge based on wavelet transform

小波变换可以很好地对结构的损伤进行精确定位和相对损伤程度的识别。本文以简支桥梁为模型进行了数值模拟,从损伤定位、相对损伤程度识别等方面,验证了该方法的有效性和可靠性。

Wavelet transform can be accurately used in the damage location identification and the relative damage extent of structure. The proposed damage detection method is validated by simulation of a simply supported bridge. Many aspects are analyzed,such as detecting the location of damage,estimating the damage extent. The result shows that it is valid and reliable index for damage identification.
