Partial safety factor for concrete: the reduction based on using reduced or measured geometrical data design, γC,red3
Eurocode 2 part 1-1: Design of concrete structures A.2.2 (2) - Annex A (informative)
Under the conditions given in § A.2.2 (1), and provided that the coefficient of variation of the concrete strength is shown not to exceed 10%, the partial factor for concrete may be reduced to γC,red3.
Recommendation
The recommended value of the partial factor γC,red3 is 1,35.
