D. To design an HBBB connection
To design a horizontal brace-beam-beam gusset connection, use the following procedure.
HBBB connections apply to joints with the following
conditions:
- no column at the joint
- 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°
