Dizhen xuebao, 2023 采用随机有限断层法进行地震动模拟时，选用合理的参数描述特定局部场地近地表高频衰减特征，对评价地震动模拟结果的正确与否具有重要的实践意义。 在工程场址地震动参数预测中，如何快速确定参数的取值，是实际应用中亟需解决的问题。首先对场地高频衰减系数κ0与平均剪切波速vS30的相关性进行了分析；然后，基于国内外学者计算得到的546个κ0系数，采用一定时窗内的κ0均方根值，讨论其随平均剪切波速vS30增加的变化趋势。 结果表明，虽然κ0具有明显的区域差异性，但其均方根值随着vS30的增大呈现出逐渐减小的趋势 ...

Vs30 değerine bağlı koherans modeli
European Journal of Science and Technology, 2020 Strong ground motion caused by earthquakes at every point of extended structures would not be same. This difference in ground movement has an important effect on the design of these types of structures. Meanwhile, the seismic resistant design has been lead to investigate the variability of earthquake ground motion over last decades. This variability of

Rock and Stiff-Soil Site Amplification: Dependency on VS30 and Kappa ( 0) [PDF]
Bulletin of the Seismological Society of America, 2013 A ground‐motion prediction equation (GMPE) specific to rock and stiff‐soil sites is derived using seismic motion recorded on high VS30 sites in Japan. This GMPE applies to events with 4.5≤Mw≤6.9 and VS30 ranging from 500 to 1500 m/s (stiff‐soil to rock sites).
