Rapid calculation method and device for shock absorption rate of bridge pier and readable storage medium

The invention relates to a rapid calculation method of a pier damping rate, which comprises the following steps: determining a bridge anti-seismic basic system, and establishing an anti-seismic stress and calculation model; the bridge comprises a main beam, a bridge pier and a seismic mitigation and isolation support arranged between the main beam and the bridge pier. Obtaining an internal force response of the bottom of the pier when the seismic mitigation and isolation support is not arranged so as to obtain a first shearing force and a first bending moment; acquiring internal force response of the bottom of the pier when the seismic mitigation and isolation support is arranged so as to obtain second shearing force and second bending moment; and calculating the pier damping rate. According to the method, an anti-seismic stress and calculation model is established according to a bridge anti-seismic basic system, the internal force response of the bottom of the bridge pier before and after the seismic isolati
