  • Patent number: 10815627
    Abstract: A method for improving the seismic performance of bridges by utilizing the beam body and an energy dissipation and seismic mitigation bridge bearing, which can effectively eliminate the harmful vibration of the bridge pier in the inherent frequency band, thus reducing the stress of the pier body and improving the seismic performance of the bridge pier without introducing external additional mass and looking for an installation space on the pier. The method includes the following steps: obtain the natural frequency fi, the equivalent modal mass Mi and the modal stiffness Ki of the pier in the longitudinal or transverse direction by numerical modal analysis or experimental modal test; determine the mass mi of the beam body; calculate the connection stiffness ki and the connection damping ci between the beam body and the pier; select the bearing system with above connection stiffness ki and the connection damping ci.
