A Review on Finite Element Analysis of Fibre Reinforced Polymer Reinforced Concrete Beam

A reinforced concrete beam’s structural behaviour and performance can be improved with fibre reinforced polymer (FRP) composite material. This review article investigates a reinforced concrete beam review using finite element analysis (FEA) software such as ABAQUS and ANSYS to conduct the behaviour of composite beams with FRP. The FEA model provides several mechanical indices, including load-deflection curve, component strain, and fracture propagation. The calculations performed with the effect of interface slip are taken into account and closer to experimental values, demonstrating that FEA model can reliably predict the general mechanical behaviour of composite beams under negative moments. Finally, a parametric composition of composite beams’ constant and permanent behaviour strengthened with/without FRP laminates is committed using FEA simulation method. The beams’ bearing capacity is studied concerning factors such as the FRP’s width, design location, number of layers, ratio of longitudinal reinforcement, and degree of shear connection. As a result of the negative moments applied to composite beams, the load-deflection, stiffness, and bending resistance can be significantly increased using FRP composite material. The bearing capacity is found to be highly dependent on the layout width and layer number of the FRP laminates at a low reinforcement ratio. At the same time, the increase rate becomes insignificant after three layers. The reinforcing ratio significantly affects the composite beams’ bearing capacity under negative moments but not under shear connection degree.
