In this study, a friction damper with a coupling mechanism (FDC) and an oil damper were added to the isolation layer of an isolated structure. Using the Kelvin collision analysis model, a time history analysis was performed by considering a possible impact in the isolation layer. Based on a comparative analysis of the seismic control effect, the following conclusions can be drawn. The combined isolation system proposed in this study gradually increases the attenuation performance of the isolation layer according to the magnitude of the earthquake by taking complete advantage of the FDC and oil damper and satisfies different performance requirements of the isolation layer of different magnitudes of earthquakes. In addition to the same control effect as the combined isolation system for seismic fortification intensity earthquakes, the best control effect can be achieved using a small control force for frequent earthquakes. Overall, the control effect on the acceleration of structural seismic response is pronounced. In the case of a rare earthquake, for not amplifying the seismic response acceleration of isolated structure, the maximum displacement of the isolation layer is controlled within the reserved safety range to avoid collision and damage between the isolation layer and surrounding maintenance structure.

在这项研究中，具有耦合机构的摩擦阻尼器（FDC）和油阻尼器被添加到隔离结构的隔离层中。使用开尔文碰撞分析模型，通过考虑对隔离层的可能影响来进行时程分析。在对地震控制效果进行比较分析的基础上，可以得出以下结论。本研究提出的组合式隔离系统通过充分利用FDC和油阻尼器，根据地震的幅度逐渐提高隔离层的衰减性能，并满足不同地震隔离级别的不同性能要求。除了与用于地震设防烈度地震的组合隔离系统相同的控制效果外，对于频繁发生的地震，使用较小的控制力即可达到最佳的控制效果。总体而言，对结构地震响应的加速具有明显的控制作用。在罕见地震的情况下，为了不放大隔离结构的地震响应加速度，将隔离层的最大位移控制在预留的安全范围内，以避免隔离层与周围维护结构之间发生碰撞和损坏。
