摘　　要：简要介绍了铅芯隔震橡胶支座微分型恢复力模型的发展过程及其在隔震设计中的应用.基于两个不同规格支座的压剪试验,比较了不同屈服前刚度的微分型恢复力模型与实测结果差异,对隔震设计中铅芯隔震橡胶支座屈服前刚度的合理取值提出建议.This paper describes development of differential restoring model of lead rubber bearing and its application in seismic-isolation design. Based on compression-shear tests of two bearings in different specifications, comparing difference in differential restoring model and testing results with different preyield shear stiffness, this paper gives reasonable advice on setting preyield shear stiffness of the lead rubber bearing used in seismic-isolation design.
