A steel moment resisting frame (SMRF) connection connects a vertical column to a horizontal beam. It is useful in both original and retrofit construction. A primary trunk assembly is comprised of two, vertical, parallel plates which are welded to the vertical column on opposing sides and which plates extend from the column along the sides of a horizontal beam. A secondary branch assembly is comprised of the horizontal beam and horizontal plates which are welded to the flanges of the horizontal beam. Such plates are welded also to the vertical parallel plates, thereby connecting the column to the beam. Additional plates may be welded between the web and flanges of the horizontal beam and the vertical, parallel plates and, also, between the web and flanges of the vertical column and the vertical, parallel plates.
