【Abstract】 In this paper, the dynamic characteristic of continuous bridges equipped with isolation bearings are investigated by nonlinear time-history analysis. The property of seismic excitation and the structural parameters of bridge are changed. The nonlinear properties and mutual effect of lead-rubber bearing and bridge structure are also considered.更多还原
