This paper investigates the interaction of structural steel reinforcement and strain-hardening cement composites (SHCC) in uniaxial tension. The effects of cement composite on the steel reinforced composite deformation behavior are experimentally investigated and contrasted to conventional reinforced concrete. Also, Using an expansive admixture can reduce an initial shrinkage crack and improve a prestress. Axial tension members made of both normal and high strength concrete are used to investigate tension stiffening and cracking of SHCC to determine experimentally if any relationship exists between SHCC strength and post-cracking behavior. Tension stiffening represents the tensile strength of concrete between cracks in a reinforced concrete member and can significantly affect member stiffness, deformation, and crack widths under service loads. A specimens using 30 and 100 MPa SHCC were reinforced with D16 bars. The presence of fibers controlled the splitting cracks and led to significant increases in the tension stiffening of SHCC using an expansive admixture
