Dynamic Loading Tests and Hysteretic Modelling of Damper with High-damping Rubber

Abstract

Dynamic loading tests of dampers with high-damping rubber were carried out, and the hysteretic model was proposed by using the test results. The damper with high-damping rubber has amplitude-dependent property, but its frequency-dependency is small. The proposed hysteretic model can model the amplitude-dependent property accurately by determining the model parameters on the test results . The validity of the proposed hysteretic model is demonstrated by comparing the test results with the simulations via the proposed model. Response analyses of a building subjected to an earthquake motion are carried out to illustrate the effects of the installed dampers.
