1 Tabulated diaphragm shear values are for attachment of steel deck to base steel thicknesses 5 mm ≤ t f ≤ 10 mm . For attachment to base steel thickness with range 3 mm ≤ t f
< 5 mm , diaphragm shear values should be calculated in accordance with Section 3.5.1.7 , or by using Hilti Profis DF software . 2 Tabulated LSD diaphragm shear loads are calculated with a phi factor ( Φ ) of 0.75 for wind loads . To calculate LSD values for load combinations involving earthquake , divide values in table by 0.75 and multiply by a phi factor ( Φ ) of 0.55 . Panel buckling has been checked . 3 Please refer to footnotes 3 through 7 on page 171 .
