摘要

本文提出了采用橡胶隔震支座刚度因子计算隔震支座竖向刚度的方法，在此基础上提出了适于工程应用的简化计算式。研究还进行了２种不同橡胶６种规格共１２件试验体的竖向刚度及水平刚度试验。文末给出了该计算结果与试验结果的对比，表明本文所提计算方法适合于工程使用。
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.
