This invention relates to the field of
seismic isolation and vibration reduction
engineering technology, and discloses a friction
pendulum bearing capable of resisting uplift forces. This friction
pendulum bearing includes a liner unit, a support unit, a reset unit, and a limiting unit. The liner unit includes a
steel ball-shaped liner and pressure-bearing sliding plates symmetrically arranged on the upper and lower sidewalls of the
steel ball-shaped liner. The support unit includes an upper support and a lower support arranged opposite to each other, and
retaining ring assemblies arranged on the opposite sidewalls of the upper and lower supports. The reset unit includes
flange plates respectively arranged on the sidewalls of the upper and lower supports and a reset member connecting the opposite
flange plates. The friction
pendulum bearing of this invention dissipates
seismic energy through the conversion of
kinetic energy,
potential energy, and
thermal energy during frictional sliding. It has a compact overall structure,
high load-
bearing capacity, and can reliably withstand and transmit forces when the
superstructure of a bridge or building generates forces in different directions, ensuring that it can
resist uplift forces regardless of displacement in any direction.
