This report presents a new hysteresis model of laminated rubber bearings for base isolated structures. Conventional models presented by manufacturers are not verified their propriety on estimating superstructures. Essential components of the new model are classified as follows. Non-linearity of second tangent stiffness is also highly significant as dependency of skeleton curve on strain. Unloading curve shape and variance of yielding load are significant. Hysteresis characteristics of lead-plugged rubber bearings (LRB) and highdamping rubber bearings (HDR) are idealized through assembling regression formulas. The new model is superior in expression of both variances caused by conditions of bearings and unloading curve shape.
