| Because of its unique circular sliding surface, friction pendulum bearing can limit the displacement of the bearing effectively and can automatic reset after the earthquake, so it is widely concerned. In the article, we analyzed the time-history response of the friction pendulum base-isolated structure under the influence of earthquake intensities, fortification intensity and severe earthquake intensity, so we can do research on the effect of friction pendulum bearing and the upper structure on the base-isolation structure. The main research contents are as follows:1. According to the current specification, use the Finite Element Software establish a finite element calculation model of the friction pendulum base-isolated structure, study isolation bearing mechanism and analysis model of the friction pendulum and introduce briefly the seismic waves and analysis methods used in the paper.2,Change the radius of the slide friction pendulum bearing, adjust the natural vibration periods, analysis the time-history response under different earthquake intensities when the periods are 1.5s,1.8s,2.1s,2.4s,2.7s,3.0s, study the influence of the radius of slide friction pendulum bearing structure on the absolute acceleration, shear of the floor and the displacement of the bearing.3. Analyzed the time-history response under different earthquake intensities when the friction coefficients of the bearing are 0.025,0.05,0.075,0.10,0.125,0.15, study the influence of the radius of slide friction pendulum bearing structure on the absolute acceleration, shear of the floor and the displacement of the bearing.4,Analyzed the time-history response of the structure in X and Y directions under different earthquake intensities, study the influence of the upper structure circumference and ratio between height and width on the absolute acceleration, shear and displacement of the bearing...
