Seismic design of bridges is an important branch in bridge engineering. This paper summarized the achievements and development trends of seismic design of bridges in 2019. The main conclusions are as follows: researches on the seismic response mechanism of traditional reinforced concrete bridge piers are becoming more and more refined, and the evolution and control of local damages have received more attention; For prefabricated pier, in addition to the "equivalent cast-in-place" connection, a variety of new configurations that take into account "load transmission" and "energy dissipation" simultaneously have been explored; Self-centering piers may subject to interface decompression under strong earthquakes, resulting in a rapid decrease in the structural stiffness, which is the key problem limiting its promotion; Isolation and energy dissipation devices are developed to having large capacity, deformability, and good weather resistance. Wherein, the semi-active control reveals satisfactory potential; The soil-structure interaction and pier-water interaction are involved more in seismic research, and the calculation accuracy and efficiency of the novel models have been improved. The seismic research of bridges with multi-physics coupling is of great potential.
