Modeling of the Load and Deflection Response of Concrete Deep Beams Reinforced with FRP Bars

Construction sector is developing in the same direction with technological developments. Thanks to these developments, we meet new designs. Examples for these designs are FRP (Fiber Reinforced Polymer) composites can be shown. It has become a preferred material in the construction sector due to its many benefits such as being resistant to corrosion, having high tensile strength and showing resistance to chemicals. In this study, the load and deflection at the midpoint of the span for 53 simple deep beams, reinforced longitudinally with FRP rods, were calculated (this analysis was derived from the research presented in reference number 10 in the literatüre). In section 7, new formulas suggested (equation 39 and 40) for load and deflection of RC deep beams with FRP and those formulas were derived using Eureqa, which is a symbolic regression program. The suggested formulas are compared with other methods in the existing literature. According to the comparison results, it has been determined that the real-life applicability of the suggested new formulas are higher and gives more accurate results compared to other studies.
