Concrete Stress with Additive Tension Stiffening Allowance

Resulting concrete stress as the sum of the base material response and the additive tension stiffening aggregate.

σc=σc,Basisε+Δσc

σc

Concrete stress in the tension zone

σc,Basis(ε)

Concrete stress of the base material model, for example, a damage model

Δσc

Additive tension stiffening factor for concrete stress
