摘要	Based on the concept of structural fuse, the buckling-restrained braces (BRBs) were proposed to be used in the bridge bents with double columns to improve the seismic performance of bridge in transverse direction. The seismic design parameters of bridge bents with BRBs were systematically analyzed. The relationship between length of the BRBs core and shear span ratio, the ratio of intercolumniation and diameter or side length of the pier section is derived from the viewpoint of seismic capability for the new structural system, and the length range of core section of BRBs was also determined. The elasto-plastic response spectra for a single-degree-of-freedom (SDOF) system with structural fuse was developed from the perspective of seismic demand, so that they are given in a format of easy use for the design of similar structures with a wide range of response characteristics. Furthermore, the displacement-based design method of bridge bents with BRBs was proposed based on the seismic capability and demand. Finally, the feasibility of the proposed method was validated by using the seismic design for a bridge bent example. © 2017, Editorial Office of China Civil Engineering Journal. All right reserved.
