摘要
研究了离散小波变换在混凝土框架结构损伤识别中的应用。作者通过对结构自由振动下的时程曲线做离散小波变换确定了结构刚度变化的损伤位置和损伤时刻。研究结果验证了小波变换在实际结构的损伤时别中应用的可行性。
This paper studies the applications of discrete wavelet transform to in concrete frame structures. The author acquire the damage identification damage location and the time instant of damage oc- currence by transforming the time histories with discrete wavelet. The results of this research validate the application of this method in the damage identification of practical engineering.
