| Abstract | ||
| This research presents a new technique for reinforcing concrete beams using thin wires of stainless-steel reinforcement of varying diameters (3mm, 4mm, 5mm, and 6mm). These thin steel wires have proven effective in improving stress distribution and enhancing bond strength between the reinforcement bars and concrete by increasing the contact surface area between the two materials. Additionally, this method helps prevent corrosion, which occurs over time and can cause the structural elements to collapse, especially in small reinforcement diameters, as they corrode quickly in carbon steel. The percentage of reinforcement used in the bottom reinforcement of the concrete beams varies between 33%, 67%, and 100% for each group, with the same diameter reinforcement being used in these three percentages. These are compared to a concrete beam reinforced with 8mm diameter carbon steel bars as the control beam. Despite the variation in the number of bars used in each beam and the percentage of reinforcement, this alternative method shows great potential for achieving significant results. The research demonstrates a substantial improvement in beam strength using thin wires of stainless-steel reinforcement. The experimental study involved 12 full-scale beams reinforced with stainless steel rebars of varying diameters and a control beam reinforced with 8mm steel bars. The results indicate that the tensile strength of reinforced concrete beams depends not only on the strength of the rebars but also on the surface area of the bars and their interaction with the concrete. The thin bars exhibited greater flexibility and compatibility compared to larger diameter rebars. | ||
