Abstract: Disclosed are a sliding groove type friction pendulum high-pier bridge seismic mitigation and an isolation bearing. The bearing includes an upper connecting steel plate, a lower connecting steel plate, and a frictional sliding component clamped between the upper connecting steel plate and the lower connecting steel plate. The frictional sliding component includes an upper bearing plate, a lower bearing plate, and a hyperbolic spheroid. The upper bearing plate and the lower bearing plate are disposed on corresponding connecting steel plates, and are mounted and cooperate by using a plurality of parallel protrusions and grooves. The hyperbolic spheroid is disposed between the upper bearing plate and the lower bearing plate. A plurality of hysteretic damping components, bearing positioning structures, butterfly-shaped spring components, and bearing limiting structures are disposed on opposite surfaces of the upper bearing plate and the lower bearing plate in a circumferential direction.

Abstract: Disclosed are a damping bearing in convertible antiseismic mode and a damping bridge apparatus. The damping bearing includes a bearing body, a damping component, a hydraulic component, and a connecting piece. The bearing body includes a first bearing, a second bearing, and a third bearing. The damping component includes an arc damping member. The arc damping member is located between the first bearing and the second bearing. One end of the arc damping member is connected to the second bearing, the other end of the arc damping member is connected to the first bearing by using the connecting piece, and after the connecting piece is cut off, the arc damping member is capable of sliding relative to the first bearing. The hydraulic component is connected to the arc damping member and the second bearing respectively.
