Reinforced Concrete Material Properties (Nonlinear)

The reinforced concrete material model is treated as statistically homogeneous with different tensile and compressive behaviors. It follows a “smeared” crack model where cracking and crushing are simulated via degeneration of the elasticity at integration points instead of tracking individual macroscopic cracks.
