The lead material is used as an energy dissipation device. The pure lead shows the characteristics of which the yield stress is low and the ductility is very high. The U-shaped lead damper is a one of dampers for the seismic isolation system. The performance of U-shaped damper has been confirmed by the experiments using the full-scaled damper and the scaled model. It is difficult to decide the model of restoring force characteristics of the lead damper only from the lead material testing, because the yield condition receives the effect of the bending deformation. In this paper, the basic parameters, which are necessary for the modeling of the U-shaped damper, are specified based on the experimental results of damper and the lead material testing results.
