conditions like high wind loads , shock or fatigue may require a different safety factor . Wood or steel members connected to the substrate must be investigated in accordance with accepted design criteria . 2 Multiple fasteners are recommended for any attachment . 3 The steel deck profile for the 3 ” deep composite floor deck has a minimum thickness of 20 gauge ( 0.0358 ”) and a minimum Fy = 33 ksi . Lower and upper flute width must be a minimum of 3-7 / 8 ”. Figure 1 in Fastener

Locations When Installing into Lightweight Concrete Over Metal Deck shows the nominal flute dimensions , fastener locations and load orientations for the deck profile . Structural lightweight concrete fill above top of steel deck must be minimum 3-1 / 4 ". 4 The steel deck profile for the 1-1 / 2 ” deep composite floor deck has a minimum thickness of 20 gauge ( 0.0358 ”) and a minimum Fy = 33 ksi . Lower flute and upper flute widths must be a minimum of 1-3 / 4 ” and 3-1 / 2 ”,

respectively . This deck may also be inverted as shown inFigure 2 in Fastener Locations When Installing into Lightweight Concrete Over Metal Deck . Figure 1 and Figure 3 in Fastener Locations When Installing into Lightweight Concrete Over Metal Deck show the nominal flute dimensions , fastener locations and load orientations for the deck profile . Structural lightweight concrete fill above top of steel deck must be minimum 2-1 / 2 ”. 5 For installation in the lower flute only .

Allowable loads are calculated based on a safety factor of at least 5.0 . Some conditions like high wind loads , shock or fatigue may require a different safety factor . 2 The tabulated allowable and ultimate load values are for low-velocity fasteners installed in normal weight or lightweight concrete masonry units conforming to ASTM C90 . 3 The tabulated allowable and ultimate load values are for low-velocity fasteners installed in concrete masonry units with mortar conforming to ASTM C270 , Type S . 4 The tabulated allowable and ultimate load values are for low-velocity fasteners installed in concrete masonry units with grout conforming to ASTM C476 . 5 The tabulated allowable and ultimate load values are for one low-velocity fastener installed in an individual masonry unit cell and at least 4 ” from the edge of the wall . 6 Multiple fasteners are recommended for any attachment . 7 Fastener can be located anywhere on the face shell or mortar joints as shown in the figure below . 8 Shear load direction can be horizontal or vertical ( Bed Joint or T-Joint ) along the CMU wall plane . 9 Fastener located in center of grouted cell installed vertically . 10 Shear load can be in any direction in the top of grouted cell application .
