About this detail

This structural detail provides criteria for small penetrations and grouped openings up to two feet in width within a composite floor deck. Isolated openings under six inches require no reinforcement when spacing exceeds four times the maximum hole diameter. Grouped openings with tighter spacing must be reinforced as a single combined opening per standard details, with maximum combined opening widths capped at two feet or framed accordingly. Openings wider than two feet require framed opening details, and all blockouts must be installed prior to placing concrete.
