1 Tabulated diaphragm shear values are for attachment of steel deck to base steel thicknesses 3 / 16 " ≤ t f ≤ 3 / 8 ". For attachment to base steel with range 1 / 8 " ≤ t f
< 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 LRFD diaphragm shear loads are calculated with a phi factor ( Φ ) of 0.80 for wind loads . To calculate LRFD values for load combinations involving earthquake , divide values in table by 0.80 and multiply by a phi factor ( Φ ) of 0.70 . Panel buckling has been checked .
