A ductile steel beam-to-column connection is connected between an H-beam and a column surface. The H-beam has a pair ol flange plates and a web plate positioned between the flange plates, a plastic moment capacity and a demand moment capacity. The beam-to-column connection comprises a web plate member and a pair ol flange plate members. The web plate member is disposed at an end ol the H-beam integrally formed with the web plate ol the H-beam. The pair ol flange plate members are also disposed at the end ol the H-beam and respectively integrally formed with the flange plates. One ol the flange plate members includes a tapered zone that is non-uniform.
