    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.

    Oct 05 2020 All the columns failed in a compression failure mode due to concrete crushing. The GFRP bars developed higher tensile strains in the HSC due to the axialflexural load compared to columns made with normal-strength concrete NSC. A minimum reinforcement ratio of 1 in the case of HSC proved practical.
