| Abstract: | The paper presents a method for analyzing the vertical stiffness of rubber bearings by a new concept of stiffness factor, and a simple formula is derived on the basis of stiffness factor method. Total 12 specimens, corresponding to 2 types of shear moduli of rubber and 6 types of shape fac tors, are tested by using a standard method to confirm the new stiffness factor method. Finally, the comparison results between computation and test show that the new method can be used effectively in engineering. |
