<p>Fiber-reinforced polymer (FRP) has emerged as a promising alternative to steel bars. Polyvinyl Alcohol Fiber (PVA) bars are often used in concrete. However, the effect of the rate of temperature change on the fracture properties of concrete requires critical investigation. The study aims to investigate the dynamic fracture analysis of PVA-reinforced concrete exposed to different rates of temperature change, including 0&#xa0;°C/min, 0.042&#xa0;°C/min, and 0.01&#xa0;°C/min under a flexural bending test. Non-contact full-field testing methods, including Digital Image Correlation (DIC) and Acoustic Emission (AE) systems, were employed to analyze fracture behavior. This analysis was coupled with the use of a bubble spacing coefficient analyzer to investigate the effect of temperature change rate on fracture properties. The results indicated that the bending strength of the PVA-reinforced concrete decreases with the increase in temperature change rate. The strain cloud map obtained through DIC analysis provides an intuitive representation of the strain evolution and the entire crack generation and penetration process in PVA fiber-reinforced concrete. The AE technique illustrated that the cumulative value of the ringing count increases with a decrease in the temperature change rate; the established AE ringing count-load curve can reflect the entire process of compressive failure in PVA fiber-reinforced concrete. The study provides vital information regarding the reinforcing effect of PVA in concrete, highlighting its advantages, such as improving crack resistance and reducing permeability due to shrinkage and temperature change, which are problematic in cold regions. PVA fibers contribute to the longevity and structural integrity of concrete in cold regions.</p>
