Partial and correlation factors for ultimate limit states and recommended values

A.1 Partial factors and correlation factors

(1)P The partial factors γ for ultimate limit states in persistent and transient design situations, and the correlation factors ξ for pile foundations in all design situations, shall be those mentioned in this annex.

A.2 Partial factors for equilibrium limit state (EQU) verification

(1)P For the verification of equilibrium limit sate (EQU) the following partial factors on actions γ_F shall be applied:

• γ_G;dst on destabilising unfavourable permanent actions;
• γ_G;stb on stabilising favourable permanent actions;
• γ_Q;dst on destabilising unfavourable variable actions;
• γ_Q;stb on stabilising favourable variable actions.

NOTE The values to be ascribed to γ_G;dst, γ_G;stb, γ_Q;dst and γ_Q;stb for use in a country may be found in its National annex to EN 1990:2002. The recommended values for buildings in EN 1990:2002 are given in table A.1.

(2)P For the verification of equilibrium limit state (EQU) the following partial factors on soil parameters γ_M shall be applied:

• γ_φ' on the tangent of the angle of shearing resistance;
• γ_c' on effective cohesion;
• γ_cu on undrained shear strength;
• γ_qu on unconfined strength;
• γ_γ on weight density.

NOTE The values to be ascribed to γ_φ', γ_c', γ_cu, γ_qu, and γ_γ for use in a country may be found in its National annex to this standard. The recommended values are given in table A.2.
