| چکیده | ||
| Reinforced Cement Concrete (RCC) structures experience progressive deterioration and cracking, which reduces their service lifetime and durability characteristics. The research investigates a dual repair method that incorporates epoxy grouting together with Carbon Fiber Reinforced Polymer (CFRP) wrapping for restoring and reinforcing RCC beams. Epoxy injection works as an internal crack treatment while CFRP wrapping reinforces structures from the outside. A critical assessment determines the joint effect of the methods on structural properties while filling a research gap because past studies evaluated them separately. In the experimental study, six RCC beams were tested under different loading conditions and different wrapping configurations, including bottom-only, U-shaped, and end-strip enhanced CFRP patterns. The results shows that the combined method significantly improves both crack resistance as well as load carrying capacity. The U-shaped wrapping provided 80% more load capacity, whereas end strips enhanced strength capability up to 140% relative to standard wrapping methods. When using two-point loading, it yields superior outcomes compared to single-point loading specimens due to optimal load distribution. The results demonstrate that the epoxy–CFRP hybrid technique provides a durable, efficient, and sustainable method for strengthening RCC members. This repair technique provides useful benefits for infrastructure maintenance purposes, especially when structures become old or show signs of damage. The study also lays a foundation for further exploration into optimized wrapping configurations under varying environmental and loading conditions. | ||
