A stiffening Method of existing cylindrical steel piers is studied by experimental ways. On the experimental way steel piers are stiffened by rectangular steel plates on it. On the Stiffening structures are set using the plates and local buckling points created forcibly on the pier. The part of the pier which yields local buckling is controlled in base zone of it by this Stiffening structures and the ductility of the piers are improved with small increase the ultimate strength of it. We have been able to improve the ductility of piers by the Stiffening structures..
