A comprehensive methodology for the validation of simulated ground motions is presented. The suggested methodology can be geared toward any ground‐motion simulation method and seismic response assessment, in a target engineering application. The methodology is founded on the comparison between conforming groups of ground‐motion waveforms from recordings and simulations and their effect on a representative collection of structures that represent the engineering application. The comparison considers the statistics of earthquake scenarios at the level of the event and site parameters, the resulting waveform characteristics, and the subsequent structural responses. Regression models are developed at three levels (between structural responses and waveform characteristics, structural responses and event and site parameters, and waveform characteristics and event and site parameters). Similarities between the models from groups of recorded and simulated ground motions guide the validation process. The validation methodology is applied to CyberShake (v.15.12) simulations and for the estimation of the column drift ratio of a bridge structure. It is shown that CyberShake (v.15.12) can be used to assess the median seismic response of the used bridge. Some discrepancies between simulations and recordings are observed, which could be attributed to the basin and site‐response models used for simulations. Further implementation and refinement of the suggested methodology are recommended to make broader conclusions.

用于地震响应评估的模拟地震动的验证方法：在基于Cyber​​Shake源的地震动中的应用

提出了一种用于验证模拟地面运动的综合方法。在目标工程应用中，建议的方法可以适用于任何地面运动模拟方法和地震响应评估。该方法基于对来自记录和模拟的地面运动波形的符合组之间的比较，以及它们对代表工程应用的代表性结构集合的影响。该比较考虑了事件和站点参数级别的地震场景统计信息，所产生的波形特征以及后续的结构响应。回归模型分为三个层次（结构响应和波形特征，结构响应以及事件和站点参数，波形特征，事件和地点参数）。来自记录的和模拟的地面运动的组之间的模型之间的相似性指导验证过程。该验证方法适用于Cyber​​Shake（v.15.12）仿真，并用于估算桥梁结构的立柱漂移率。结果表明，Cyber​​Shake（v.15.12）可用于评估所用桥梁的中值地震响应。观察到模拟和记录之间存在一些差异，这可能归因于模拟所用的盆地和场地响应模型。建议进一步实施和完善建议的方法，以得出更广泛的结论。该验证方法适用于Cyber​​Shake（v.15.12）仿真，并用于估算桥梁结构的立柱漂移率。结果表明，Cyber​​Shake（v.15.12）可用于评估所用桥梁的中值地震响应。观察到模拟和记录之间存在一些差异，这可能归因于模拟所用的盆地和场地响应模型。建议进一步实施和完善建议的方法，以得出更广泛的结论。该验证方法适用于Cyber​​Shake（v.15.12）仿真，并用于估算桥梁结构的立柱漂移率。结果表明，Cyber​​Shake（v.15.12）可用于评估所用桥梁的中值地震响应。观察到模拟与记录之间存在一些差异，这可能归因于模拟所用的盆地和场地响应模型。建议进一步实施和完善建议的方法，以得出更广泛的结论。这可以归因于用于模拟的盆地和场地响应模型。建议进一步实施和完善建议的方法，以得出更广泛的结论。这可以归因于用于模拟的盆地和场地响应模型。建议进一步实施和完善建议的方法，以得出更广泛的结论。
