In this paper, shear strain dependence of high hardness laminated rubber bearings were studied through tests. The shear strain dependency test is considered the changes by increase the shear strain by 50%, 100% and 150% based on 100% of total rubber thickness. As the test results shear strain increases were identified a tendency to decrease the shear stiffness.

Noise and vibration is the most problematic thing in the rail way bridges. In this study, we compared the vibration reduction test of two types of Spherical bearing. The results of the experiment were able to get the following conclusion. The elastomer layered spherical bearings vibration reduction performance is two times better than that of the steel type spherical bearing.
