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 ASD diaphragm shear loads are calculated with a safety factor (Ω) of 2.35 for wind loads. To calculate ASD values for load combinations involving
earthquake, multiply values in table by 2.35 and divide by a safety factor (Ω) of 2.50. Panel buckling has been checked.
