【Abstract】 Characteristics of precast concrete structure was elaborately introduced in this paper as well as its seismic performance.And the research progress of seismic mitigation and isolation(SMI) in improving the seismic performance of precast concrete structure for the past few years was described,including base isolation system,inter-storey isolation system,installation of beam-column joint energy dissipation dampers,et al.Considering the effectiveness of SMI technology in improving structural seismic performance,a summary of the wide application status of the SMI technology in precast concrete structure was presented.The future development direction of the SMI technology in precast concrete structure was then talked about.Based on the deficiency of SMI technology in improving the seismic performance of precast concrete structure,it is suggested that multi-dimensional SMI theory and the new SMI devices should be paid more attention in the future research.更多还原
