1 Tabulated diaphragm shear values are for attachment of steel deck to a base steel thickness , 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 .
