- Abstract:
- In this paper,the statistic analysis of peak ratios in vertical and horizontal acceleration(V/H)is done by using strong ground motion data.It is shown that V/H obeys the lognormal distribution.Based on the data,the effects of magnitude,epicentral distance,site conditions,and focal mechanism on V/H are analyzed.The results show that the effect of magnitude is inconspicuous,and V/H is reduced as the epicentral distance is increased,especially on soft soil site.In the near-field(R≤60 km),V/H on soil site is bigger than it on rock site,and it is opposite in the far-field.In addition,the focal mechanism affects to V/H greatly,especially in the near-field.
