Based on the material characteristics of the sector lead viscoelastic dampers(SLVD),the relationship between appropriate structural parameters and restoring force equation was given,and the restoring force model of SLVD was derived.The design method of the damper was given out.The performances of the damper were tested under low frequency cyclic load.The results were compared with those of the numerical simulation and the test.The investigation results indicate that:the mechanical properties of the sector lead viscoelastic damper are mainly depended on rubber and lead and the symmetric bilinear model can be used to describe the restoring force of the damper.The experimental and numerical simulation results of SLVD hysteretic curve are in good agreement.It is feasible to adopt the given model to simulate the damper element.
