Wavelet transform based method is investigated to identify the damage location of structures by using the spatial domain information of structures. Structure deformation curve is decomposed in one scale by using the bi-orthogonal wavelet bior6.8 to identify the damage locations of uniform and non-uniform cantilever beams. The results show that the spatial domain information wavelet transform can reveal structural damage location very efficiently. Considering the complexity of civil engineering structures and incompleteness of input, a wavelet transform based method is proposed to identify the damage location of structures by using their vibration profile under ambient excitation. The proposed method is applied to the damage detection of tall electricity transmission tower. It is shown that the method can identify the damage location of high-rise latticed tower with uniform stiffness or gradual changing stiffness along the height effectively, but fails for the latticed tower with abrupt change in stiffness.

利用空间域信息进行小波变换的结构损伤位置识别方法。采用双正交小波bior6.8对结构的位移曲线进行一个尺度的小波分解,精确地识别了等截面和渐变截面悬臂梁的损伤位置,验证了空间域信息小波变换方法对结构损伤位置识别的有效性。针对土木工程结构的复杂性、输入不完备性等特点,提出了利用环境激励下的结构振动曲线进行小波变换的结构损伤位置识别方法,并将该方法应用于大型输电铁塔的损伤位置识别。结果表明,该方法能有效地识别沿高度刚度均匀分布或渐变的高耸格构式塔架的损伤位置,但对存在刚度突变的塔架,则无法有效地识别刚度突变处的损伤。
