Analysis of Frame Structure Base-Isolation Based on ETABS

The traditional seismic structure and the baseisolation structure of frame structure are analyzed based on ETABS finite element analysis program of the building.Compared to the inherent characteristics,the inherent period is extended and the inherent frequency is reduced by adopting base-isolation structure;the seismic response of base-isolation structure is reduced by adopting spectrum analysis,time history analysis and energy analysis to analyze the dynamic characteristics of frame structure,thus,base-isolation structure has the function of isolating the effect of earthquake.
