Design method of seismic isolation structure for metro depot upper cover development

A design method of a seismic isolation structure for metro depot upper cover development adopts the arrangement of the seismic isolation structure to reduce the seismic response of the metro depot upper cover development structure, meanwhile, the stress condition of a lower structure is improved due to the reduction of the seismic response of an upper structure, the section of a lower frame column can be effectively controlled, and the service life of the metro depot upper cover development structure is prolonged. The anti-seismic property of the whole structural system is remarkably improved, and the safety and reliability of the structure are guaranteed; in addition, one layer of top floor is reduced for the two-layer structure within the projection range of the upper structure; the mass of the second layer is greatly reduced, the earthquake response is further reduced, the overall stress condition is improved, the section of the first layer frame column is effectively controlled, and the manufacturing cost
