Structural Behavior of Reinforced Self-Compacted Engineered Cementitious Composite Beams by Bashar S. Mohammed, M. F. Nuruddin, Muhammad Aswin, Nursyuhada Mahamood, Hashem Al-Mattarneh

“…Results show that failure modes in flexure and shear of R-SC-ECC beams are comparable to that of normal reinforced concrete beam. Nevertheless, contrary to VecTor2, models of EC2 and RILEM are not suitable for predicting reasonable ultimate moments for the beams, while results using VecTor2 model have successfully predicted the failure modes and load-deflection curves for all R-SC-ECC beams. …”
