摘要
从小波变换的基本原理出发,利用小波能量特性及正交特性,根据加速度记录推导出小波变换下的地震地面运动的能量时程公式,通过小波变换后求得的能量同时包括了地震动时域和频域内的能量,而且这种方法从理论上是可行,从方法实现上也是比较简单的。
Based on wavelet＇ s fundamental, energy and orthogonal characteristics ＇a computational formula of earthquake ground motion energy time-history is proposed,which is calculated by acceleration records. The energy not only includes time-domain energy of the earthquake ground motion but its frequency-domain energy. This method is practicable on theory, and it is very simple.
