1 Tabulated diaphragm shear values are for attachment of steel deck to base steel thicknesses, t f , with the range 16 gauge (1.5 mm) ≤ t f ≤ 6 mm.
2 Tabulated LSD diaphragm shear loads are calculated with a phi factor (Φ) of 0.65 for wind loads. To calculate LSD values for load combinations involving
earthquake, divide values in table by 0.65 and multiply by a phi factor (Φ) of 0.60. Panel buckling has been checked.
