Does Concrete02 material considers concrete crushing mode? I mean, for example, if one of the columns fails due to crushing of concrete, does this material capture it? I know that we cannot model rebar buckling and reber fracture failure mode with a fiber element. I was wondering if i could capture concrete crushing failure mode with this material.

This command is used to construct a modified uniaxial Kent-Scott-Park concrete material object with degraded linear unloading/reloading stiffness according to the work of Karsan-Jirsa and no tensile strength. The modification is to model the effect of Stuff In The Cracks (SITC). The command is as follows:
Heavy damage (medium to major damage): spalling and crushing of concrete, buckling of reinforcement, or shear failure in columns were observed, and lateral resistance of shear walls might be reduced by heavy shear cracking; and • 3. Collapse (partial and total collapse), which also included those buildings demolished at the time of investigation.
