Examining Strain and Bending Deformation Parameters From Nonlinear Static Analysis of Concrete, Reinforced Concrete, and Fiber-Reinforced (FRP ) Concrete Samples

Abstract

Fiber-made composite materials as fiber-reinforced polymers (FRPs) in polymer resin media are today replacing traditional materials and existing procedures. Thus, the present study was aimed at examining the strain and bending deformation parameters from nonlinear static analysis of concrete, reinforced concrete and fibers-based reinforced concrete samples. In this research, FRP effects on strain and bending deformation parameters from nonlinear static analysis of concrete, reinforced concrete, and fibers-based reinforced concrete samples were examined using the finite element method and ABAQUS software. This study, carried out by the force control method, yielded the maximum strain values of the lower and upper surfaces of the models along with the maximum bending values in the middle of each beam span for all three models. The findings suggested that FRP-reinforced bending significantly reduced the bending deformation value. This study found that the FRP had reduced the bending by 80%, as the use of an FRP plate of 1.4 mm thick significantly reduced the middle of the span bending.
