International ClassesE04B 001/19E04B 001/38 AbstractA 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.Field of SearchMultilevelFloor intermediate wall ends Superimposed vertical structure with spacing horizontal structure Horizontal structure includes component of settable material Abutting vertical structure at horizontal structure juncture Cross bracing On column (e.g., elevated floor) Trihedral shafts-type corner Barrier or module seated on projecting means on vertical structure COPLANAR SUSTAINERS; E.G., JOIST TO WALL (SEE 52/702) Outside corner or peripherally bordered (i.e., framing, etc.) Framework Having specific connector, etc. Fusion bond, e.g., weld, etc. Metallic fusion material Added bonding material, e.g., solder, braze, etc. Axially bolted or riveted INTERFITTED MEMBERS WITH EXTERNAL BRIDGING PIECE | |
