Re: ACI crack control

[Subject Prev][Subject Next][Thread Prev][Thread Next]
William,

Thanks for your reply. In fact I was looking for control of flexural
cracking.
I see that ACI 350 is still using the old z factor, and the new ACI 318-02
has a different
approach, but not covering structures subjected to special enironmental
conditions.
Will ACI 350 be refreshed, in the light of ACI 318-02 or something ?
Best Regards,

Raul Labbé  S.E.
