General method of second order analysis: the value of γCE
Eurocode 2 part 1-1: Design of concrete structures 5.8.6 (3)
With stress-strain diagrams based on design values, a design value of the ultimate load is obtained directly from the analysis. In the k value of Expression (3.14), Ecm is substituted by:
|Ecd = Ecm/γCE||(5.20)|
The recommended value for γCE is 1,2.
