Description Of Bridge Bearing Pad
It is made from multilayers of rubber sheets and steel plates, by high temperature vulcanization bonding. It has enough vertical stiffness, and can transfer the counter-force of superstructure to abutment. It has good elasticity for beam end rotation, and better shear deformation for horizontal displacement of superstructures.
