About this detail

This structural detail provides sizing schedules, framing layouts, and reinforcement requirements for openings in metal deck and composite floor slabs. Steel angles ranging from L3x3x3/16 to L6x4x3/8 (LLV) serve as perimeter framing around openings up to 7'-0" in dimension, supported by steel joists or beams as shown on plan. Concrete slab openings require two #5 bars placed on each side of the opening, alongside two #5 by 5'-0" bars positioned diagonally at each corner. Pre-engineered adjustable framing systems are acceptable alternatives to angle framing subject to structural engineer approval. Maximum equipment load on framing is limited to 1000 pounds (1.0 kips).
