Connecting structure with three-dimensional shock absorption and energy absorption buffering

Abstract

Provided is a connecting structure with three-dimensional shock absorption and energy absorption buffering. During an earthquake, a rotational connecting device enables an upper structure to only undergo a rigid body swiveling around the rotational connecting device and rock as a whole within a design-allowed range. Further, energy is absorbed and dispersed through deformation and energy dissipation of vertical connecting devices to mitigate earthquake impact on the upper structure. The above device achieves earthquake resistance and shock absorption, effectively reducing damage and destruction to the upper structure under strong earthquakes. The connecting structure has strong self-centering capability and is capable of effectively controlling its residual displacement after earthquake, thus preventing further damage to the upper structure and facilitating its repair. With earthquake resistant capability of the upper structure enhanced by the connecting structure, seismic performance requirements on design of the upper structure are lowered, thereby offering economic benefits.
