Recommendation of Ranked Typical Seafloor Ground Motions Records According to Characteristic Classification

  • 摘要: 面向海域工程抗震设计及评估对海底地震动的需求,基于日本相模湾海域K-NET的ETMC海底强震动记录,根据震级、震中距选取面向工程输入的949组地震动记录数据库。在考虑震源类型差异的基础上,对地震动峰值、持时、频谱等参数进行分析,通过反应谱、Arias烈度等指标描述典型海底地震动特征。根据峰值加速度、显著持时等强度指标对海底地震动记录进行排序,给出基于不同地震动特征分类下的典型地震动记录。推荐的海底地震动可为考虑不同结构需求参数的典型海域工程结构时程分析提供输入地震动。
