Finite Element Modeling (FEM) of GFRP Bar Reinforced Concrete Beam: Flexural Behavior

Abstract:

This paper presents flexural analysis of a GFRP bar reinforced concrete beam by using Finite Element Modeling (FEM) approach. The FEM model is developed using solid element for concrete and bar element for GFRP reinforcement. Results from FEM show good agreement with the reported experimental result under service loading, in terms of load vs. mid-span deflection. The first cracking load from FEM matches analytical solution fairly well, while ultimate flexural capacity of RC beam from FEM shows 8.3% higher than that calculated with ACI 440 Equation.
