This study employs Digital Image Correlation (DIC) to analyze the behaviour of concrete cylinders confined with Fiber Reinforced Polymer (FRP) under uniaxial compression. The DIC technique provides a non-contact, high-resolution method to capture detailed strain distributions, offering precise insights into the performance of Carbon Fiber Reinforced Polymer (CFRP) and Steel Fiber Reinforced Polymer (SFRP) confined concrete cylinders. DIC findings reveal complex deformation patterns, localized strain regions and detect subtle strain variations that conventional strain measurement methods fail to capture, offering a deeper understanding of FRP-confined concrete behaviour and failure mechanisms. This study demonstrates the potential of DIC as a precise, reliable, full-field strain measurement tool with significant implications for analyzing behaviour and optimizing the design of FRP-confined concrete. Moreover, DIC’s non-contact strain measurement capabilities establish it as a versatile instrument for research and engineering applications, advancing experimental analysis and structural performance assessment across a broad range of fields.
