【Abstract】 In this paper, the elasto plastic displacement ratio spectra, which reflects the relationship between the plastic maximum relative displacement seismic response and elastic maximum relative displacement seismic response of SDOF is studied through a great amount of numerical computation. The mean spectra of elasto plastic displacement ratio are acquired, so as to provide the fundamental datum and reference material for further research of simplified method of checking the elasto plastic deformation of structures and for new seismic design method based on elasto plastic displacement of structures.更多还原
