1 Tabulated diaphragm shear values are for attachment of steel deck to base steel thicknesses , t f , with the range 1 / 8 " ≤ t f
≤ 6 mm . 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 .
