Multi-stage friction energy dissipation type bridge support and energy dissipation method
The invention belongs to the technical field of bridge components, and particularly discloses a multi-stage friction energy dissipation type bridge support and an energy dissipation method. Comprising an upper seat plate and a limiting bottom plate, and a sliding limiting cavity is formed in the limiting bottom plate; the lower seat plate is arranged in the sliding limiting cavity, a first sliding gap is formed between the lower seat plate and the sliding limiting cavity, a sliding plate is arranged between the bottom face of the lower seat plate and the limiting bottom plate, a rotating cavity is further formed in the lower seat plate, the sliding plate is slidably connected with the limiting bottom plate, the friction coefficient of the sliding plate and the limiting bottom plate is small, and the free deformation requirement under the bridge operation load is met; the middle plate is arranged in the rotating cavity, a friction plate is arranged between the middle plate and the upper seat plate, the friction plate is fixedly connected with the middle plate and slidably connected with the upper seat plate, the friction coefficient between the friction plate and the middle plate is large, energy can be consumed when the main beam has large displacement in the longitudinal bridge direction, and the bridge damping and energy dissipation requirements are met. The support has the two-stage motion characteristic, and the requirements of a bridge for operation load and earthquake action are met respectively.
