Based on threelarge earthquake acceleration records collected in SMART 1 array in Taiwan, the values of envelope function of vertical ground motion and parameters in the functionare calculated. Thespatial variabilities of each parameters of the function are analyzed, and the experential prediction formulas are suggested.
