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.
