Description

TECHNICAL FIELD

[0003] Traditional structural seismic design methods mainly rely on the strength, stiffness and ductility of the structure itself to resist seismic action, which will result in an increase in the amount of structural materials, and the increase in the amount of materials will increase the self-weight of the structure, and the corresponding seismic response will also increase, reducing the use efficiency.

[0004] At present, more and more group buildings in China are exploring the use of seismic isolation structures to achieve seismic effect. Seismic isolation structures block the transmission path of seismic forces by setting seismic joints to reduce the seismic force on the structure. The setting of seismic joints cannot affect the normal use function of the building. Common building deformation joints can usually only resist the influence of single-direction displacement on the structure, so it is necessary to propose a deformation joint method that meets the multi-directional free displacement of seismic mitigation group buildings under complex seismic action. While meeting the daily use function of the building, it can effectively resist the adverse effects of structural collision damage or structural disconnection caused by multi-directional displacement under seismic action.
