摘要	86 suites of acceleration records from the 9 earthquake events around the world were selected and processed for extracting some essential ground motion parameters. The ratios of vertical to horizontal peak ground acceleration, vertical and horizontal acceleration response spectra and predominant period were mainly investigated statistically. The results indicated that the average ratio of vertical to horizontal peak ground motion is 0.78, and the ratios of more than 60% stations are greater than the rule of thumb, 2/3.This ratio decreases with the increasing epicentral distance. The curves of vertical to horizontal acceleration response spectrum ratios with period from 0 to 6 second have "Z" shape generally. The shapes of vertical and horizontal acceleration response spectrum vary within the different period range. And the vertical acceleration response spectrum achieves the maximum value at the smaller period comparing to the horizontal acceleration response spectrum. For most of stations, the ratio of vertical to horizontal predominant period is less than 1.0.And this ratio increases with the increasing epicentral distance. Finally, influence coefficients, attenuation index and characteristic period of vertical seismic effect for the seismic design code should be prescribed separately.
