Textile Reinforced Concrete (TRC) is a thin and lightweight cement-fibre composite material. In this study, the mechanical performance of TRC under quasi-cyclic loading is evaluated through an experimental program. TRC specimen of size 500 x 60 x 10 mm with four layers of AR- glass textile fibers were prepared and tested under uniaxial tensile quasi-cyclic loading. The load- deflection response and stiffness degradation are evaluated to understand the damage progression in TRC. The result indicates substantial stiffness degradation from 17% to 60% in Zone II due to multiple crack formation indicating an accelerated deterioration process. The combined DIC and AE analysis shows that matrix cracking and crack initiation cause dense and high-frequency AE activity up to the multiple cracking zone (<0.2% strain). As cracks stabilize, widen, and propagate at increasing strain, the density of AE events reduces.
