Which failure type is most likely as the cross-sectional area of rebar decreases in a concrete beam?

💡 Explanation

A brittle tensile concrete fracture occurs because less rebar reduces tensile strength, causing concrete cracking at lower strain, therefore leading to sudden concrete failure, rather than ductile steel yielding requiring sufficient rebar area.
