What is it about?
It is very important to have a unified methodology to perform sectional analysis for different concrete members with different types of reinforcement (steel, FRP,...etc.) and hybrid concrete. The presented in this paper methodology offers a more complete solution for the general shape sections of various structural concrete members for the strain, stress, curvature, and deflection before and after cracking and extends to estimate the ultimate strength under different static load combinations. This methodology considers tensile strain softening and tension stiffening of concrete in the strain-stress analysis of the concrete members as primary mechanisms, occurring first, and the tension stiffening of steel bars due to the tensile resistance of the surrounding concrete layer only much later as a secondary mechanism, occurring after the concrete tensile stress attained the strength limit.

Why is it important?
To avoid using different procedures for different concrete members
Perspectives
Comparison to different experimental data, the methodology proved its reliability to simulate the behavior of different concrete members.
