英文摘要	In order to provide references for design of new bridges and the retrofitting of the existing ones with isolated bearings, a displacement-based seismic design method for medium span highway bridges was developed based on seismic design code and technical standard of isolated bearings in China. The design method provided references for choosing appropriate size of isolated bearings and estimating the design target displacement, and the displacement distribution method of pier-bearing system was carried out according to mechanics characteristic of system in series. The yield of pier was allowed in the design, but no repair was needed after ground motions through the control of damage degree. Also, the design required test the safety of bearings. Taking 36 continuous beam bridges with different configurations and different span lengths for examples, the feasibility was verified through dynamic time-history analysis. The results show that the proposed method can predict displacement requirement of girder better and is easy to master the performances of bearings and piers. The method is also suitable for irregular bridges, which can judge the lateral displacement deformation mode of girder through lateral displacement variation coefficient. © 2016, Editorial Department of China Journal of Highway and Transport.
