Finite Element Analysis of Axially Loaded GFRP-Reinforced Concrete Hollow Square Columns

Hollow concrete columns are often employed in bridge constructions because of their lighter weight and effective section characteristics. In addition, to reduce the issue steel reinforcement corrosion create a strong light construction, hollow also reinforced with bars made fiber-reinforced polymer. This research aimed analyze effect GFRP (glass fiber polymer) on compression strength square under an axial concentric load. The finite element application ABAQUS 2019 version was used simulate model, calibrated utilizing experimental data from previous studies for various geometric models material specifications reinforcement. findings model exhibit excellent agreement. Finally, according parametric study's results, A analysis is done assess impact changing ratio, spacing between ties, inner-to-outer width comparison computational results clearly show how Increased longitudinal ratio improves columns' bearing capability, but when compared reinforcement, it provides less capability. For optimum outcome columns, advised adopt limit i/o 0.27 0.38. stirrups shown not significantly capacity load columns.
