Performance of a Lead Rubber Damper under Cyclic Lateral Loading

Abstract:

This study investigates the performance of a new lead rubber damper (LRD), which is more advanced than existing lead-rubber based isolation devices. In contrast to the existing devices, multiple lead cores are installed in the LRD in order to optimize the behavior of the laminated rubber and lead. It is able to perform effectively under the application of shear force. An experiment was performed to investigate its dependency on the level of shear strain and frequency. The damping ratio, energy dissipation capacity and effective stiffness of the device were also evaluated.
