本文运用分支模态综合法对从国外引进的大型、高耸、瓷质电容器贮架进行了地震反应的数值分析与研究。计算结果表明，无隔震基础的贮架其地震内力将大大超过材料的容许应力，因而倒塌是不可避免的；但采用隔震基础并适当选取隔震基础的水平弹簧刚度系数，则可使其地震内力大大降低，贮架的安全得到切实的保证。本文的研究工作为此类电气贮架的国产化定型设计提供了一定的理论依据和计算方法。
In this paper, the branch modality synthesis method is used to analyze and study the seismic response of the large, high-rise, porcelain capacitor storage rack imported from abroad. The calculation results show that the seismic internal force of the storage frame without isolation base will greatly exceed the allowable stress of the material, so the collapse is unavoidable; however, using the isolation base and appropriately selecting the horizontal spring stiffness coefficient of the isolation base can make it The internal force of the earthquake is greatly reduced and the safety of the storage rack is effectively guaranteed. The research work in this paper provides a certain theoretical basis and calculation method for the localization and design of such electric storage racks.
