1 Tabulated diaphragm shear values are for attachment of steel deck to a base steel thickness , t f
≥ 1 / 4 ". 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 . 3 Please refer to footnotes 3 through 7 on page 171 .
