ABSTRACT: Conventional lead-rubber bearings may have a problem of instability and unrecovered deformation against a strong ground motion. Also, their lateral stiffness is too flexible to resist the braking forces in railway bridges. Therefore, it is hard for the bearings to be used for railway bridges.
