The analysis is focused on the effects of the storey number of of the rubber, the mass of the intermediate steel plates and the structural parameters of the laminated rubber bearing.

BIL located between pile caps and the super structure, mainly consisting of laminated rubber bearings and viscous dampers.

Study on vertical repetition load fatigue test of rubber bearing;

A Simple method for computing vertical stiffness of rubber bearings;

A series of real-time hybrid loading tests on velocity-dependent rubber bearings are conducted by using the test system.

Test study on vertical property of rubber isolators;

In order to reveal the tension property of rubber isolators and verify the new tension stiffness stress-strain computation model proposed in this article, the author investigated the relations between vertical tensile force and deformation property, and relations among the biasing tension origin stiffness under shear tension state, horizontal stiffness, damping and shears strain.
