A seismic resilient precast concrete frame structure includes precast solid columns, precast composite beams, T-shaped shear connectors having notches, and anti-buckling energy-dissipation connecting plates, wherein the precast composite beams are connected to the precast solid columns and each include a precast composite middle beam and precast composite cantilever beams arranged at two sides of each of the precast composite middle beams; tops of the precast composite cantilever beams and the precast composite middle beams are connected by the T-shaped shear connectors having notches, and the notches in the T-shaped shear connectors having notches are located at a neutral bending moment point of the frame structure under the action of a vertical load; and side surfaces of the precast composite cantilever beams and the precast composite middle beams are connected by means of the anti-buckling energy-dissipation connecting plates.

Seismic resilient precast concrete frame structure and construction method therefor

The present invention relates to a prefabricated infilled panel-frame structure capable of accommodating seismic-loading and seismic energy dissipation, and a construction method thereof, including a frame body, a prefabricated infilled panel group, a panel connector, and a disc spring assembly. During an earthquake, the present invention slides to dissipate energy only after the maximum starting sliding force is exceeded, thus providing the structure with a relatively high lateral stiffness prior to sliding. After an earthquake, the disc spring assembly of the present invention may provide a certain restoring force due to being compressed so as to reduce the residual displacement. Further, the present invention achieves the bidirectional deformation cooperation of the prefabricated infilled panel under earthquakes, so that the infilled panel may still achieve the function of seismic energy dissipation under the coupling action of in-plane and out-of-plane loads.
