Abstract
This research presents the findings of a numerical simulation conducted using the ABAQUS/CAE Finite Element (FE) software, with the purpose of investigating the behavior of short concrete columns constructed using recycled aggregate reinforced by Glass Fiber Reinforced Polymer (GFRP) bars. The numerical validation technique included an analysis of the experimental data of twenty columns constructed utilizing recycled aggregate reinforced by steel or GFRP rebars. Additional aspects, such as the column length, acting as an indicator of column slenderness, and the configuration of the column section, were also investigated. The results revealed a significant correlation between the failure loads and axial displacement of the computational models and those derived from the experimental methods. It was found that the increase in the column length was inversely proportional to its load carrying capacity. The drop percentage in the load carrying capacity was 6% and 11% for columns with length of 1100 mm and 1500 mm, respectively, compared to the reference square column with 700 mm length. The drop percentage in the load carrying capacity was 6.9% and 12.7% for columns with lengths of 1100 mm and 1500 mm, respectively, compared to the reference circle column with 700 mm length.
