About this detail

Ceiling struts connect to fire-proofed structural steel beams using various attachment configurations including clipped angles and modified strut ends. Option 1 utilizes a ten-gauge clip measuring one and one-half inches by one and one-half inches by three inches minimum, secured to the beam flange with two power-actuated fasteners having a minimum diameter of zero point one four five inches. The flattened end of the strut fastens to the clip using two number ten sheet metal screws, placed tight to the structure. Option 2 employs a twelve-gauge clip of the same profile, connecting to a slotted tube end with two number ten by two-inch sheet metal screws. The channel strut option features cut and bent flanges attached directly to the beam underside with two power-actuated fasteners. All supporting structural steel members must be a minimum of three-sixteenths of an inch thick, and power-actuated fasteners are prohibited within the protected zone of any steel member per AISC 341.
