| 摘 要： | 基于离散正交小波变换的快速Mallat算法,用紧支集正交小波db6对地震动加速度时程进行了分解,随后将该分解结果用于求解多自由度弹性体系的地震反应。通过实例计算,发现小波变换法的计算结果与用振型分解法计算的结果较接近,说明该方法用于地震反应分析是可行的。

| Abstract: | Based on the Mallat algorithm of discrete wavelet transform, the decomposition of acceleration process of ground motion due to earthquake is obtained by strict support orthogonal wavelets db6. Subsequently, the decomposition is adopted to solve the response of the elastic multi-degree-of-freedom structural systems subjected to earthquake. The calculation example shows that the result of the wavelet transform method is close to that of the mode-decomposition method,so the application of wavelet transform to the solving of the response of the elastic multi-degree-of-freedom structural systems subjected to earthquake is feasible. |
