The influence of different safety formats proposed by Eurocode 2 on the deformability and design of slender structural elements

Second order effects in slender concrete columns-reformulation of the Eurocode 2 method based on nominal curvature

“…Critics to the NCM are also made in [10,11] where is pointed out that the method gives conservative results because in some case overestimates curvature. The different safety formats used in EC2 for non linear analysis are discussed in [12], namely using a partial safety coefficient or an overall safety factor.…”
