Discussed in this paper is the vertical load supporting mechanism of laminated rubber bearings with hollow circular sections. The compressive stiffness of the hollow circular rubber bearings is analytically studied. Key issues discussed in this paper are 1) derivation of the governing equation that determines the compressive stiffness of the device 2) effect of bulk modulus on the compressive stiffness 3) proposition of a simple formula which is close to the rigorous solution. As a result of this analytical study, the compressive stiffness of the rubber bearings is proved to be 20 % smaller than is expected from the commonly used conventional model.
