Confined Concrete

[fabbrob1]

Hi,

Which kind of law do you use for the confined concrete?

As you know, in defining material characteristics, i have to input yelding stress and strain and ultimate stress and strain.

In lots of article and book i haven't been able to find stress at fracture both for the confined and unconfined concrete.

have you got some reference to constitutive law which define all these 4 parameters?

Thank you very much!
