Feb 01, 2013  Steel-fiber-reinforced concrete (SFRC) is an efficient cement-based composite material that can compensate for the drawbacks of the material properties of conventional concrete and has better structural performances than conventional concrete. It can improve torsional behavior as well as flexural and shear behavior.

Torsional responses of steel fiber-reinforced concrete ...

This study introduces two analytical approaches to estimate the torsional behavior of steel fiber reinforced concrete (SFRC) members. The first approach utilized the tensile constitutive relationship of SFRC in tension derived from SFRC panel test results, and the second approach adopted the direct tension force transfer model, which were applied to the smeared-truss model.

Reinforced concrete - Wikipedia

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually embedded passively in the concrete before the concrete ...
