A mechanical model for predicting the triaxial behavior of high-damping rubber bearings under bidirectional horizontal deformations and axial load is presented in this paper. This new model is developed by combining two existing models, both of which have been previously proposed by the authors. Tests of isolation bearings under bidirectional horizontal loading with different axial load levels were conducted. The experimental formulae for the bidirectional hysteresis model in the mechanical model were identified from the test results. The proposed model is shown to be capable of expressing the influence of the bidirectional deformations and axial load on the hysteresis loops.
