Wood or steel members connected to the substrate must be investigated in accortlance wifh accepted design criteria. 2 The steel deck profile is 3"deep composite floor deck with a thickness of 20 gauge{0.0358"). Figure 1 (Section 32.1 1.6)shows the nominal flute dimensions, fastener locations and load orientations for the deck profile. 3 Structural lightweight concrete fill above top of inetal deck shall be a minimum of 3-t/4"deep. 4 Multiple fasteners are recommended tor any attachment.
