The utility model relates to a bridge transverse
damper with resetting and grading
energy consumption functions, which particularly comprises a beam bottom connecting plate, a limiting baffle, a beam bottom connecting plate bolt, a
pier top connecting plate bolt, a steel rod right end nut, a steel rod left end nut, a steel rod, an SMA disc spring group, a triangular steel plate and a
pier top connecting plate. The triangular steel plate is connected with the
pier top connecting plate, a round hole is formed in the upper portion of the triangular steel plate, the limiting baffles are connected with the beam bottom connecting plate, the limiting baffles are provided with horizontal guide grooves, the SMA disc spring groups are arranged between the adjacent limiting baffles and the triangular steel plate, and the steel rod sequentially penetrates through the guide grooves of the limiting baffles, the SMA disc spring groups and the round hole in the upper portion of the triangular steel plate. And the steel rod right-end nut and the steel rod left-end nut are screwed at the thread tooth opening at the end part of the steel rod, so that the bridge transverse
damper with resetting and graded
energy consumption functions is formed. Under frequent earthquakes, the SMA disc spring group is used for providing energy dissipation and reset capacity, and under rare earthquakes, the triangular
steel plates generate plastic deformation to dissipate
earthquake energy.
