n this paper, the earthquake resistance-energy dissipation(ERED) bearing is equivalently simplified as the linear Kelvin component, and the vibration differential equations of continuous beam bridge used ERED bearings are dened.

Application of isolating bearings in 3 long span spacing structures of Guangzhou Gymnasium is introduced in this paper.

Due to complex nature of excitations and the inherent dynamic characteristics of restoring force of a base isolation system,the response of a rubber bearing subject to strong earthquake is very complicated.

In the paper,experimental research on shaking table of isolated structure model with lead-plug rubber bearing under the action of two-direction earthquake waves has been conducted,which is of height-width ratio 5 and a scale of 1∶16.
