The reasons of the damage rate at the bottom of piers in Wenchuan earthquake are also analyzed. Furthermore, the difference of the seismic load transmission path and the energy dissipation mechanism should be paid attention when the modifications and suggests of seismic specifications citing directly from the provisions of American or Japan. Combining with the difference on seismic performance of elastomeric pad bearing, lead rubber bearings, high damping rubber bearing, friction pendulum system, the view that bearings should be used as fuse-like elements in the seismic design is proposed. Referred to the design method of American and Japan, seismic design method of small and medium spans bridge considering bearing friction slipping is given in this paper. Seismic design methods of multilevel fortification and hierarchical energy dissipation are also suggested. Finally, the corresponding failure modes in longitudinal and transverse direction are proposed and some questions need to be studied are also discussed.
