Lead-rubber-dampers to install on building exterior for seismic retrofit was proposed and tested. Dependency of the strength and stiffness on the displacement amplitude and frequency was evaluated through cyclic loading tests. The elastic stiffness of the experimental bi-linear model for the proposed damper was influenced by loading frequency, while the peak load of the damper was affected by the displacement amplitude, primarily.
