ANALYSIS ON RELATIONSHIP BETWEEN 3-LEVEL EXCEEDING PROBABILITY(EP) AND HORIZONTAL PGA

    Graphical Abstract
    • Abstract
  • Based on the results obtained from seismic safety evaluation of 35 engineerng sites,the relationship between 3-level EP and horizontal seismic peak ground acceleration(PGA) is statistically analyzed.The result indicates that,the ratio of PGA corresponding to EP above 63% after 50 years to PGA corresponding to EP above 10% after 50 years and the ratio of PGA corresponding to EP above 2% after 50 years to PGA corresponding to EP above 10% after 50 years does not obviously change in different site situations.
