Abstract

In this research, the flexural fatigue performance of Textile Reinforced Concrete (TRC) panels is experimentally evaluated. TRC panels made of four layers of E-glass textile fibres are prepared and tested under a three-point bending configuration in conjunction with the Digital Image Correlation (DIC) technique. The load-deflection response, stiffness degradation, and crack propagation are evaluated to understand the fatigue damage progression in TRC panels, and a comparison is drawn between its monotonic and fatigue behaviour. From the analysis, it is realized that the fatigue strength of TRC panels could be considered until when fatigue deflection value reaches 70 % of the deflection value corresponding to the strain-hardening peak load of monotonic response. The DIC results reveal that the failure of TRC specimen due to fatigue loading takes place at a significantly lower crack width compared to the monotonic loading. Further, the TRC panels under fatigue fail with sufficient warning through visible large deformation, unlike plain concrete.
