D5.D.9.1 Clause 6.1 – General

The partial safety factors will use the following values:

Resistance of cross-sections, γ_M0 = 1.0
Resistance of members to instability, γ_M1 = 1.0
Resistance of cross sections to tension, γ_M2 = 1.1

The design function in STAAD.Pro sets these values as the default values for the SS-NA (NA 7 is specified)..

Note: You can change these values through the GM0, GM1, & GM2 design parameters. Refer to D5.C.6 Design Parameters

Note: If any of these parameters have been specified by the user as "0", STAAD.Pro will ignore the specified value and use the default values as given above.
