| Abstract: | 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. |

| Keywords: | lead rubber bearing differential restoring model preyield shear stiffness |
