1 Tabulated diaphragm shear values are for attachment of steel deck to base steel thicknesses , t f , with the range 16 gauge ( 0.0598 ") ≤ t f
≤ 1 / 4 ". 2 Tabulated ASD diaphragm shear loads are calculated with a safety factor ( Ω ) of 2.35 for wind loads . To calculate ASD values for load combinations involving earthquake , multiply values in table by 2.35 and divide by a safety factor ( Ω ) of 2.50 . Panel buckling has been checked . 3 Please refer to footnotes 4 through 8 at the end of Section 1.6 on page 60 .
