Abstract

Use of the damper using laminated high damping rubber for the seismic retrofit of an existing long cablestayed bridge is in progress. A scaled model of the laminated rubber damper consisting of plural laminated high damping rubber assemblies was examined by quasi-static loading tests for the verification of the performance as vibration control device system. The test results show that the damper system exhibits sufficient damping and energy absorption capability, and axial load dependence of the damping force characteristics is small. The masimum shear strain capacity of the high damping rubber assembly exceeding 300% is vefiried by a single-cycle and a cyclic loading tests. Therefore, the current design methodology of the laminated rubber damper is valid and can be regarded as a effective vibration control device for a long cable-stayed bridge.
