D5.D.4.1 Clause 6.1(1) – General: Partial Safety Factors for buildings
EN 1993-1-1:2005 specifies the use of the partial safety factors to be used in for design as given in Cl. 6.1 of the code. These factors are γM0, γM1, and γM2. EN 1993 provides default values for these factors. However, any National Annex is allowed to override these default values.
The partial safety factors will use the following values:
- Resistance of cross-sections - γM0 = 1.05
- Resistance of members to instability - γM1 = 1.05
- Resistance of cross sections to tension - γM2 = 1.25
The design function in STAAD.Pro sets these values as the default values for the Norwegian-NA (NA 3 is specified).
Refer to the basic code (EC3) for a description of these clauses. The sections below refer to the corresponding clauses in the Norwegian -NA.
