Unveiling the failure mechanism of concrete cover separation in FRP flexural-strengthened RC beams

Key Points

• Concrete cover separation occurs in flexural-strengthened reinforced concrete beams, indicating a design flaw.
• Key findings show that reduced bond strength in FRP applications leads to this failure mechanism.
• Analysis of concrete cover behavior under stress provides insights into structural integrity in engineering designs.
• Understanding these mechanisms may enhance the overall safety and efficacy of future strengthened structures.
