Hi everyone,

i saw in EN 13480 (ed 2012) that the allowable stress for sustained loads is defined as "ff" (and not fh ?!)

sustained :
sigma 1 < ff (formula 12.3.2-1)
with ff = min {Rp0.2t/1.5 ; Rm/2.4} (formula 5.2.1-1)

it's the same for occasionnal loads ("sigma2 < k.ff"), and even for liberal stress (sigma4 < "fa+ff")

does Caesar take this into account ??? what version ?

it seems to me that it doesn't, does anybody knows why ?

thx by advance for your help,
Alcor.
