Disclosed is a resettable roll-in type swinging seismic-isolation pier stud with flanges. The resettable roll-in swinging seismic-isolation pier stud is of a resettable seismic-isolation structure. The seismic-isolation pier stud comprises a main beam, piers, bearing platforms, semi-protruding spherical pier bottoms, pier flanges, rubber spacers, hollowed semispherical bearing platform tops, shape memory alloy shear bolts and oblique-section stoppers. The fixed connection of the piers and the bearing platforms is changed into swingable hinge connection. The spherical pier bottoms of the piers are embedded in the hollowed hemispheres of the bearing platform tops. The pier flanges are arranged on two sides of the upper portions of the spherical pier bottoms and are in anchorage connection with the bearing platforms via the shape memory alloy shear bolts. The rubber spacers are arranged between the semi-protruding spherical pier bottoms and the hollowed semispherical tops and between the bearing platforms and the pier flanges as well as between the sides of the pier flanges and the bearing platform stoppers. The pier stud is separated from the foundation, and seismic energy can be filtered by swinging, so that the piers and the foundation are protected. The resettable roll-in type swinging seismic-isolation pier stud has excellent social and economic benefits and worthy of popularization and application.
