Flexural Performance of PVA Reinforced ECC Beams: Numerical and Parametric Studies

Engineered cementitious composite (ECC) refers to the group of cementitious mixtures possessing the strainhardening and crack control abilities. In this research, the mechanical performance of ECC beams will be investigated with respect to the effect of aggregate size and amount, by employing nonlin...
