1 Tabulated diaphragm shear values are for attachment of steel deck to base steel thicknesses 3 / 16 " ≤ tf ≤ 3 / 8 ". For attachment to base steel with range 1 / 8 " ≤ tf < 3 / 16 ", diaphragm shear values should be calculated in accordance with Section 3.5.1.7 , or by using Hilti Profis DF software .
2 Tabulated S ASD diaphragm shear loads are calculated with a safety factor ( Ω ) of 0.80 for wind loads . When a safety factor ( Ω ) of 2.00 for wind loads is used , the S ASD diaphragm shear loads in this table can be increase by 17.5 %. To calculate S ASD values for load combinations involving earthquake , multiply S ASD values in table by
0.80 and divide by a safety factor ( Ω ) of 2.50 . Panel buckling has been checked . 3 Please refer to footnote 3 through 7 on page 171 of Hilti North American Product Technical Guide Volume 1 : Direct Fastening
