英文摘要	Aiming at a system of rubber bearings serially connected with columns, its natural frequencies were investigated, and the effects of axial load and different rubber bearings were discussed. Taking the effects of cross-section rotatry, shear distortion and compression axial force into account, the mathematical model for free vibration of the system was established. The differential quadrature method was employed for discretizing the governing equations and the boundary conditions. The natural frequencies of the system with clamped-free boundary conditions were solved numerically, and the curves of natural frequencies versus compression axial force were presented. It was shown that increase in axial force reduces the lower order natural frequencies significantly, and in cases of the unchanged total height, decrease in the equivalent bending stiffness of rubber bearings reduces the natural frequencies to a certain level.
