This paper studies the effect of soil–structural interaction (SSI) on gravity‐based wind turbine towers equipped with tuned mass dampers (TMDs) subjected to earthquake loading. A small‐scale shaking table test of wind turbine towers with TMD was conducted, and the results showed that using TMD designed considering SSI resulted in larger vibration suppression. A simplified analytical numerical model was developed for SSI analysis considering TMD. The effect of soil site class and the earthquake intensity on the response reduction efficiency of the TMD was also discussed using the simplified model. It is concluded that the TMD efficiency depends not only on the soil stiffness but also on the characteristics of the applied ground motions, both of which are affected by the site classes and earthquake intensity levels. Moreover, the peak acceleration ratio (PAR), the root mean square acceleration ratio (RAR), the peak displacement ratio (PDR), and the root mean square displacement ratio (RDR) of the top of the wind turbine tower were obtained with and without TMD for different earthquake intensities and sites. These parameters can be used as references for the rational selection of TMD parameters considering SSI.

土-结构相互作用对调谐质量阻尼器设计的影响，以控制具有重力基座的风力涡轮机塔架的地震响应

本文研究了土-结构相互作用（SSI）对重力型风力涡轮机塔架的影响，该塔架装有承受地震载荷的调谐质量阻尼器（TMD）。进行了带有TMD的风轮机塔架的小型振动台试验，结果表明，使用考虑SSI设计的TMD可以更大程度地抑制振动。考虑到TMD，为SSI分析开发了简化的分析数值模型。还使用简化模型讨论了土壤位级和地震烈度对TMD响应降低效率的影响。结论是，TMD效率不仅取决于土壤的刚度，还取决于施加的地震动的特征，两者都受场地类别和地震烈度水平的影响。而且，在不使用TMD的情况下，获得了风轮机塔顶顶部的峰值加速度比（PAR），均方根加速度比（RAR），峰值位移比（PDR）和均方根位移比（RDR）。针对不同的地震烈度和地点。这些参数可用作考虑SSI的TMD参数合理选择的参考。
