Abstract
This paper discusses the stability of laminated rubber bearings with high damping materials both theoretically and experimentally. The specimens adopted for this study were tested under static loading before shaking table tests were conducted to check their dynamic stability. As a result of the static loading test we have obtained the fact that the geometrical nonlinearity can be separated from the material nonlinearity under large deformation. The shaking table tests also support the stability criterion that is predicted from the geometrical nonlinear theory, which has been proved by the static loading tests in the previous studies. This paper successfully explains the coherence between the experimental results and the theoretical predictions expected from the rigorous solutions based on the nonlinear model we have developed in the previous study.
