Abstract：Based on the single-mass model, the earthquake response of different natural period isolation structure are analyzed by using the equivalent linear method and time history analysis method according to the China, Japan and USA code in the paper. Through the comparison of acceleration response spectra, it is found that the response spectrum in long period part of design response spectrum of China code is too large. According to the results of time history analysis, the modified equation to the long period part is proposed based on the original acceleration response spectrum. In the end of the paper, the earthquake response of isolation structure is compared by using the new suggestion modified acceleration response equation and time history analysis method, and the results obtained with the modified long period response spectrum is consist with the results of time history analysis. The response analysis results by using the suggestion equation of response spectrum value have ideal higher analysis precise for isolated structures.
