About this detail

A large framed floor or roof opening in a steel deck assembly with maximum opening widths up to eight feet features W10x19 or W8x15 edge beams framing the opening perimeter unless space is one foot four inches or less, in which case edge beams can be eliminated per plan notes. Three-quarter-inch diameter shear studs are provided along the beams at twenty-four inches on center with a minimum count per beam as specified. Edge plates and perimeter reinforcement are installed per typical edge details at openings. Two number four reinforcing bars measuring three feet six inches long are placed at each corner diagonally. General notes instruct to reference un-framed opening details for smaller voids and coordinate with architectural and mechanical drawings.
