A new macro has been included with the program to generate load combinations for the Strength limit state per Eurocode – Basis of structural design, BS EN 1990:2002+A1:2005.

The load combination generator is capable of creating load combinations per equations 6.10, 6.10a, or 6.10b found in Cl. 6.4.3.2.

These equations specify the following combinations of loads:

 $Σ j ≥ 1 γ G , j G k , j + γ p P + γ Q , 1 Q k , 1 + Σ i > 1 γ Q , 1 ψ 0 , 1 Q k , 1$ (6.10)

Alternatively, for the strength limit state, the less favorable of equations 6.10a and 6.10b may be used:

 $Σ j ≥ 1 γ G , j G k , j + γ p P + γ Q , 1 ψ 0 , 1 Q k , 1 + Σ i > 1 γ Q , 1 ψ 0 , 1 Q k , 1$ (6.10a)

 $Σ j ≥ 1 ξ j γ G , j G k , j + γ p P + γ Q , 1 Q k , 1 + Σ i > 1 γ Q , 1 ψ 0 , 1 Q k , 1$ (6.10b)

where
 Gk = Permanent actions P = Prestress actions Qk = Variable actions
Note: The effects in each of the above equations are always additive. If any effect is negative (that is, would reduce the final sum), its effect is taken as zero.
