Assessment of Full-Scale Thin Wire Reinforced Concrete Beams

This research introduces a novel technique for reinforcing reinforced concrete (RC) beams by employing thin wire reinforcement bars of varying diameters (3mm, 4mm, 5mm, and 6mm), these steel thin wires which have small diameter from diameter (from 2mm to 8mm)(slender wires) have been proven to enhance stress distribution more effectively and enhance the bond strength between steel rebars and concrete by increasing the contact surface area between the two materials. Additionally, the percentage of the used bottom reinforcement for all beams remains constant at 100%, similar to the control beam, despite variations in the number of bars utilized in each beam, this alternative approach has the potential to significantly yield results. The research demonstrates a substantial improvement in beam strength through the utilization of thin wire rebars. The experimental investigation involved five full scale beams reinforced with mild steel rebar diameters. The results indicate that the tensile strength of reinforced concrete beams is influenced not only by the strength of the rebars but also by the surface area of the steel bars and their interaction with the concrete. Thin rebars exhibit superior flexibility and compatibility compared to larger diameter rebars. The experimental program yielded positive outcomes in terms of flexural capacity, deflection, ductility, and energy dissipation.
