Abstract
The invention relates to a variable-curvature self-adaptive friction pendulum seismic mitigation and absorption bearing. A seismic absorption period of a friction pendulum bearing adopted in the field of bridge construction is determined once the spherical radius is determined, but the fixed period results in poorer adaptive capacity of a structure. The variable-curvature self-adaptive friction pendulum seismic mitigation and absorption bearing is provided with a bispherical lining plate, wherein an upper bearing plate and a base are arranged at the upper part and the lower part of the bispherical lining plate; slide block components are arranged on the lower surface of the bispherical lining plate; a limitation plate fixed on the base and guide bar components are arranged at the periphery of the upper bearing plate; and two curved surface friction pairs are formed among the upper bearing plate, the bispherical lining plate and a variable-curvature bottom plate. According to the variable-curvature self-adaptive friction pendulum seismic mitigation and absorption bearing, resonance of the traditional friction pendulum bearing is overcome by adopting a variable-curvature surface; reliable contact between relational structures of the bearing with different curvature radiuses, and the friction surface contact adaptivity are achieved by the slide block components; local stress concentration is avoided; seismic mitigation and absorption function separation on the normal working condition and the earthquake working condition is achieved; the stress is stable and reliable; beam falling is avoided; and multistage protective seismic mitigation and absorption effects are obvious.
