Concrete07 – Chang Mander’s 1994 Concrete Model

Concrete07 is an implementation of Chang Mander's 1994 concrete model with simplified unloading and reloading curves. Additionally the tension envelope shift with respect to the origin proposed by Chang and Mander has been removed. The model requires eight input parameters to define the monotonic envelope of confined and unconfined concrete ...
