Friction pendulum type energy dissipation damping device and structural damping system

The utility model provides a friction pendulum type energy dissipation damping device and a structural shock absorption system. Relates to the technical field of bridge seismic isolation. Comprising a top plate, a damping mechanism and a bottom plate, the damping mechanism comprises a lining plate and an energy dissipation steel plate which are in butt joint, a spherical crown protruding block is arranged on the side, facing the bottom plate, of the lining plate, a spherical crown groove is formed in the bottom plate, the spherical crown protruding block is attached to the spherical crown groove to form a friction pendulum damper, and the lining plate is connected with the bottom plate through a shear pin; one end of the energy-dissipation steel plate is connected with the top plate, and the other end is connected with the lining plate; the friction pendulum damper and the mild steel damper are overlapped, second-order energy consumption is achieved through the difference of deformation responses of the frict
