Abstract: Eight large reinforced self compacting engineering cement-based composite (r-sc-ecc) beams with different reinforcement ratios were designed, prepared, poured and cured, and the failure tests were carried out at the age of 28 days. The experimental results are compared with the theoretical values predicted by EC2, RILEM and Vector2 models. The results show that the bending and shear failure modes of r-sc-ecc beams are equivalent to those of ordinary reinforced concrete beams. However, contrary to Vector2, EC2 and RILEM models are not suitable for predicting the reasonable ultimate bending moment of beams, while the results of Vector2 model are used to successfully predict the failure modes and load deflection curves of all r-sc-ecc beams. It has been concluded that r-sc-ecc belongs to the pipeline categorylity class medium to high which gives advantages of using R-SC-ECC beams in regions susceptible to seismic activities.
