1 Tabulated diaphragm shear values are for attachment of steel deck to base steel thicknesses , t f , with the range 1 / 8 " ≤ t f
≤ 1 / 4 ". 2 Tabulated ASD diaphragm shear loads are calculated with a safety factor ( Ω ) of 2.00 for wind loads . To calculate ASD values for load combinations involving earthquake , multiply values in table by 2.00 and divide by a safety factor ( Ω ) of 2.30 . Panel buckling has been checked . 3 Please refer to footnotes 3 through 7 on page 171 .
