A Finite Element Approach to Evaluate and Predict the Shear Capacity of Steel Fiber-Reinforced Concrete Beams

Adding steel fibers to a concrete matrix enhances the shear capacity of reinforced beams. A comprehensive understanding this phenomenon is essential evaluate engineering designs accurately. The Steel Fiber Reinforced Concrete (SFRC) beams affected by many parameters, such as ratio span effective depth SFRC beam, compressive strength concrete, longitudinal reinforcement ratio, volume fraction, aspect and type fibers. Therefore, cover influence these parameters on beams, 91 from previous studies, divided into 10 groups, were considered in current study. Two approaches have been used predict first approach 7 predicting equations derived studies second one finite element analysis (ANSYS software) simulate Despite structure elements, there no reliable able satisfactorily study does. log file ANSYS software was calculate results show reasonable agreement with experimental tests. extracted much closer more realistic than those obtained equations. Also, χ factor (squared value predicted capacity) 97%, while closest proposed equation gives 91%.
