Self-adaptive eddy current damping conical friction pendulum support and installation method and application
The invention discloses a self-adaptive eddy current damping conical friction pendulum support and an installation method and application thereof.The pendulum support comprises a support top plate and a support bottom plate which are oppositely arranged up and down, a sliding block is hinged to the center of the bottom of the support top plate, a conductor plate is fixedly connected to the outer edge of the sliding block in the circumferential direction, and a permanent magnet set is embedded in the bottom of the conductor plate; a friction plate is arranged at the bottom of the sliding block; the support base plate is provided with a sliding face used for sliding of the sliding block, and the sliding face is provided with a copper plate matched with the sliding face in shape. The sliding surface comprises a flat plate sliding surface positioned at the central position, a variable-curvature sliding surface positioned on the outer ring of the flat plate sliding surface and tangent to the flat plate sliding surface, and a slope sliding surface positioned on the outer ring of the variable-curvature sliding surface and tangent to the variable-curvature sliding surface. An eddy current damping energy dissipation mode is utilized, a damping energy dissipation mechanism is improved, and self-adaptive adjustment of damping energy dissipation of the support can be achieved under different earthquake intensities.
