This strain hardening response occurs after thefirst cracking of the material. In this paper, experimental and theoretical studies were conducted toassess the influence of using HPFRCC material instead of normal concrete in RC beams. Thetheoretical results for simply supported beams with different values of compressive strengths arepresented and compared with the available experimental data. Results indicate that using HPFRCCmaterial instead of normal concrete in RC beams concludes to more ultimate load, deflection andductility compared to normal reinforced concrete beams. Moreover, new theoretical equations areproposed for estimating the flexural characteristics of reinforced composite and reinforcedHPFRCC beams. Results show that the flexural capacity of reinforced HPFRCC beams is about6.4% higher than that of RC beams. Moreover, flexural capacity of experimental reinforcedHPFRCC beams is about 11.2% higher than that of theoretical values.}, keywords = {Concrete,HPFRCC,flexural capacity,ultimate deflection,ultimate load}, url = {https://ijstc.shirazu.ac.ir/article_2417.html}, eprint = {https://ijstc.shirazu.ac.ir/article_2417_01659b756b5ec19579ae7ef9d917f91d.pdf} }
