Flexural Behaviors of Double Reinforced Beam with High-Performance Cement Composite and Steel Bar

This paper describes the flexural behaviors of double reinforced beams with strain hardening cement-based composite (SHCC) materials and high-performance steel bar (HPSB). To evaluate the effects of cement composite type and strength on flexural response of reinforced beam, three specimens made and tested under monotonic flexural loading. Test results indicated that superior flexural and uniaxial performance with multiple fine cracking are observed for SHCC materials compared to those of conventional high strength concrete (HSC). Specifically, HPSB reinforced beam with SHCC materials exhibits more effectively crack-damage mitigation and flexural performance than that with HSC.
