According to EN 1992-4,7.2.1.3 and 7.2.1.4 and ETA-15/0785 partial safety coefficients on the resistance side of
yM = 1.5 and on the action side of yG = 1.35 were taken into account.
All the specifications in the European Technical Assessment ETA-15/0785 must be taken into account when dimensioning.
