Moment connections for structural steel frames and construction methods thereof

Abstract

An assembly for a moment connection between a steel beam and a steel column includes a bracket and a clamp. The bracket and the clamp can be made of steel and are configured to be slidably connected to one another. The bracket is configured to be affixed to the column. The clamp is configured to be affixed to an end of the beam. The bracket has an elongated body. The clamp includes a hollow structural member extending laterally to the length direction of the beam. The clamp also includes first to third bars extending from a vertical sidewall of the hollow structural member in the length direction of the beam, toward the bracket. The first to third bars define a space between them that houses the bracket inside. The first to third bars surround the bracket in a way that forms a moment connection between the clamp and the bracket.
