Analytical Model for Elastoplastic and Creep-Like Behavior of High-Damping Rubber Bearings
In the present study, a new analytical model of high-damping rubber bearings (HDRBs) for time-history analysis is proposed. The proposed model is used in the evaluation of elastoplastic and creep-like behavior of HDRBs under bidirectional seismic and strong wind loading. The analytical model was developed by reducing the degrees of freedom of a new type of constitutive law that was proposed by the authors for finite-element analysis of seismic isolation bearings. First, the validity of the proposed model for time-history response analysis was examined through various tests of HDRBs under unidirectional and bidirectional loading. The analytical results agreed well with the test results. Next, wind loading tests were conducted and the reproducibility of creep-like behavior of HDRBs under wind loading was evaluated. The effectiveness of the proposed model was verified by the tests, and the limitations of the applicability of the proposed model were determined.
