【Abstract】 The differential hysteretic restoring force model is used to simulating the characteristic of restoring force of isolation bearings.Through the analysis of dynamic properties on large bay multi-ribbed slab frame structure with base isolated,it is proved that the seismic response of large bay multi-ribbed slab frame structure could be greatly reduced by means of base isolation techniques,so that the superstructure can be achieved the seismic fortification demand and fulfilled the building functional desire.更多还原
