设计地震波的小波包多尺度调整

Multi-Scale Adjustment for Design Earthquake Accelerogram by Wavelet Package

提出了一种基于小波包对地震动在不同尺度上进行调整的方法。和传统的小波分析相比 ,该方法不仅对地震波低频分量进行精确调整 ,还可对其高频成分实现类似的调整。本文提出的方法可方便地应用于时频联合分析和结构抗震设计中。

Wavelet package is introduced to adjust for design earthquake accelerogram in different scales. Compared with classic wavelet technique, the method can adjust not only the low frequency components of earthquake wave, but also the high frequency components. This makes the approach more versatile and realistic for time-frequency analysis and seismic protection design of architectural structures.
