三水准超越概率水平地震动峰值加速度关系分析

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

    摘要
  • 摘要: 以35个工程场地地震安全性评价结果为样本,统计分析了三水准超越概率水平地震动峰值加速度(PGA)关系。结果表明:50年超越概率63%和2%地震动峰值加速度与50年超越概率10%地震动峰值加速度的比值,在不同场地类别条件下变化不显著。

     

    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.
