D. To design an HCBB connection

To design a horizontal brace-column-beam gusset connection, use the following procedure.

HCBB connections apply to joints with the following conditions:
  • at least one column with an H section at the joint
  • column is vertical (perpendicular to beams)
  • two perpendicular beams with H section and one brace with an angle section
  • beams should be parallel with the ground (X-Z plane when Y is up)
  • the brace should be in the same plane with the beams, with the angle between the brace and either beam between 30° and 60°
  1. Start the Connection Design workflow and select the applicable load envelope.
  2. Select a joint that matches the joint requirements.
  3. On the Connection Design ribbon tab, select the Gusset Connection tool in the Assign Connections group.

    The Gusset Connection dialog opens.
  4. Select an AISC design code from the Design Code drop-down list.
  5. Select Gusset Plate HCBB from the connection template drop-down list.
  6. Double-click the HCBB_CA template to add it to the selected list.
  7. Click OK.
  8. Double-click the connection list view to review the connection design. The connection pad opens.
  9. (Optional) If the girder and beam have been incorrectly specified, they can be changed:
    1. On the Connection Design ribbon tab, select the Beam and Girder Identification tool in the Frames group. The Beam-Girder Identification dialog opens.
    2. Check the Swap option for the beam-girder connection you want to switch.
    3. Click Switch.
    4. Click OK.
    5. Repeat step 8 to open the connection design again.
