The present invention provides a design method for a replaceable energy-absorbing tie beam for improving the seismic performance of a double-column pier of a bridge, and relates to the technical field of seismic resistance and shock absorption data processing. By designing key parameters such as shear strength, shear yield energy consumption, flange width-to-thickness ratio and stiffness ratio and strength ratio of an energy-absorbing section, the designed replaceable energy-absorbing tie beam can preferentially dissipate seismic energy through damage and deformation of the energy-absorbing section under the action of small and medium earthquakes. Under the action of a large earthquake, the seismic energy can be dissipated jointly by shear deformation of the energy-absorbing beam section, overall damage of the transverse tie beam, and "limited" plasticity of the pier column, thereby achieving the purpose of expected graded energy consumption. The introduced graded energy consumption differentiation index M1 further enhances the adaptability of the design, and the precise control of the structural performance is achieved by dynamically adjusting the key parameters. After the earthquake, only the damaged part of the replaceable energy-absorbing tie beam needs to be replaced to quickly restore the structural function of the bridge and protect the safety of the bridge.
