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.
A structural joint connection comprising a horizontal beam connected to a vertical column, said beam having top and bottom flanges and a web between said flanges, said joint connection comprising two vertical plates disposed in parallel relationship on opposite sides of said column, said vertical plates being in face-to-face relationship with respect to each other, and welded to said column, said vertical plates extending horizontally from said column along the sides of said horizontal beam, plate means attached to said horizontal beam flanges by horizontal welds, said plate means further attached to said vertical plates by horizontal welds, said horizontal welds extending longitudinally in the direction of said horizontal beam.
A structural joint connection comprising a horizontal beam connected to a vertical column having vertical edges, said joint connection comprising two vertical plates disposed on opposite sides of said column and wherein said vertical plates are welded along vertical lines to said vertical edges of said column, wherein said vertical plates are in face-to-face relationship with respect to each other, and wherein said vertical plates extend from said column along the sides of said beam and wherein is included weld securement means attaching said vertical plates to said beam, said weld securement means comprised of welds running longitudinally in the direction of said horizontal beam on said horizontal beam and on said vertical plates.
A moment resisting frame connection comprising a horizontal beam connected to a vertical column, the combination which comprises:
