EN13480 admissibles stresses case SUS - 04/06/11 02:50 AM

hi,
i've annotated an imperfection in the C2 quick reference guide in the indication of the evaluation of the admissible stress formula for the SUS loading case, for normal and alternate options respectively:

Pcdo/4en + 0.75iMA/Z < kfn
Sl = Pcdo/4en + SbA < kfn

the correct values of admissible stress must not be multiplied by k (occasional load factor), and the formula must be

Pcdo/4en + 0.75iMA/Z < fn
Sl = Pcdo/4en + SbA < fn

(ref. par. 12.3.3-1 of EN13480)

please confirm.
thanx

The software does not multiply the "sustained allowable" by "k". You are correct, there is a typo in the Quick Reference Guide.
