The utility model discloses a two limbs are friction energy dissipation shock attenuation binder for pier relates to bridge construction technical field, including being four sleeves of X type cruciate fixation in same vertical plane, upper and lower two adjacent sleeve contained angles are alpha, establishing the sliding scale pole in the sleeve, establishing the spring between sliding scale pole and sleeve bottom, sliding scale pole outer end is fixed on two limb piers, establish the sliding friction face between sliding scale pole and sleeve, realize energy dissipation through the themogenesis of this sliding friction face sliding friction. It is continuous through sliding scale pole and two limb piers, utilize the sleeve of X type crossing to carry out horizontal sidewise restraint to the pier pier shaft, the quiet kinetic stability that has improved the pier can, the seismic energy who utilizes the friction between sliding scale pole and sleeve to bear the pier turns into heat energy through frictional h
