Friction pendulum type seismic mitigation and absorption bearing with variable friction coefficient
The invention discloses a friction pendulum type seismic mitigation and absorption bearing with a variable friction coefficient. The bearing comprises an energy-dissipating pendulum seat, a cushioning ball pendulum and a wear-resisting plate. The cushioning ball pendulum is arranged above the energy-dissipating pendulum seat; the wear-resisting plate is arranged on the energy-dissipating pendulum seat and is arranged between the cushioning ball pendulum and the energy-dissipating pendulum seat; the wear-resisting plate is provided with a plurality of regions with different friction coefficients and thus enables the friction force between the cushioning ball pendulum and the energy-dissipating pendulum seat to change along with the change of a slide position of the cushioning ball pendulum on the energy-dissipating pendulum seat; and the wear-resisting plate is of a round shape and comprises a solid circle and a plurality of concentric circles which are orderly distributed outwardly from the solid circle. The friction pendulum type seismic mitigation and absorption bearing has the advantages that by arranging the plurality of friction rings with different friction coefficients on the energy-dissipating pendulum seat, friction coefficients are increased along with the increased slide during the sliding process of the cushioning ball pendulum on the energy-dissipating pendulum seat when an earthquake happens, thereby achieving the purposes that earthquake energy is better consumed and earthquake displacement and internal force are reduced.
