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 LRFD diaphragm shear loads are calculated with a phi factor ( Φ ) of 0.70 for wind loads . To calculate LRFD values for load combinations involving earthquake , divide values in table by 0.70 and multiply by a phi factor ( Φ ) of 0.65 . Panel buckling has been checked . 3 Please refer to footnotes 4 through 8 at the end of Section 1.6 on page 60 .
