    Eurocode 0: Basis of structural design
ArticleCommentary
A1.1 (1)NA can give guidance on the design working life of certain buildings.

The user has to impose the design life time. The default is set to 50 years.
A1.2.1(1)NA can give guidance on what to do when effects of actions cannot exist simultaneously.

No specific implementation in Diamonds. You can set loads incompatible when required.
A1.2.2 (Table A1.1)NA can give guidance on which \Psi-factors to use for buildings.

When no NA is chosen in Diamonds, the \Psi-factors from Table A1.1 are used:
\begin{matrix}&\Psi_0 &\Psi_1 &\Psi_2 \\\text{Category A} &0.7 &0.5 &0.3 \\\text{Category B} &0.7 &0.5 &0.3 \\\text{Category C} &0.7 &0.7 &0.6 \\\text{Category D} &0.7 &0.7 &0.6 \\\text{Category E} &1.0 &0.9 &0.8 \\\text{Category F} &0.7 &0.7 &0.6 \\\text{Category G} &0.7 &0.5 &0.3 \\\text{Category H} &0 &0 &0 \\\text{snow FI, IC, NO, SW} &0.7 &0.5 &0.2 \\\text{snow} > \text{1000m} &0.7 &0.5 &0.2 \\\text{snow} \le \text{1000m} &0.5 &0.2 &0 \\\text{Wind} &0.6 &0.2 &0 \\\text{Temperature} &0.6 &0.5 &0\end{matrix}
A1.3.1(1) NOTE
Annex B		NA can give guidance on how to alter the partial safety factors in Tables A1.2(B) for different reliability levels (consequence classes).

When no NA is chosen in Diamonds, the KFI-factors in Table B3 are used.
A1.3.1 (Table A1.2(B))
  • NOTE 1: NA can give guidance on which equation to use for the ULS FC combinations and if (6.10a) should only include permanent loads. We’ll refer to it as “(6.10a) modified”.

    When no NA is chosen in Diamonds, you can choose between (6.10) and (6.10a&b). The default is (6.10).
    • (6.10a) modified is not implemented in Diamonds.
  • NOTE 2: The \gamma and \xi values may be set by the National annex.
    When no NA is chosen in Diamonds, it will use the following values (design lifetime 50 years and concequence class 2):
    \gamma_{Gj.sup}=1.35
    \gamma_{Gj.inf}=1.00
    \gamma_{Q,1}=1.50 (0 where favourable)
    \gamma_{Q,i}=1.50 (0 where favourable)
    \xi=0.85
A1.3.1(5) NOTENA can give guidance on which approach to use when designing structural members (footings, piles, basement walls, …) (STR) involving geotechnical actions and the resistance of the ground (GEO).

Only Approach 2 is supported by Diamonds. By consequence, only the values of Table A1.2(B) are implemented in Diamonds. The partial safety factors can manually be adjusted to those in Table A1.2(A) or (C) when needed.
A1.3.2 (Table A1.3)NA can give guidance on which \Psi-factor to use in accidental combinations.

When no NA is chosen in Diamonds, the user can choose between \Psi_{1.1} or \Psi_{2.1} to generate the ULS FI combinations.
A1.4.2(2)NA can give guidance on the serviceability criteria (for example maximum allowed displacement) to be used.

Diamonds calculates the horizontale and vertical displacements, but there is no function that will compare the calculated displacements with allowable displacements. That’s something the user must do manually.

Articles for which the NA data is implemented in Diamonds (= green articles), are listed in the national overviews below. Articles for which the NA data is not implemented in Diamonds (= blue articles), are not listed in the national overviews below even though NA data might be available.

Note (3) under Table A1.1 decribes that whenever a variable load of short term (< 1 month) is combined with another variable load of short term, \Psi_0=0.3.

This is implemented in Diamonds for wind and snow. The effect of \Psi_0=0.3 is only visible in the generated combinations , not in the dialog for the Load groups .

When any variable load other than wind is leading, use \Psi_{2.1} for the leading load and \Psi_{2.1} for the other variable loads.

This is implemented in Diamonds.
