FE validation In terms of load-displacement curves, Figs. 15 and 16 present a comparison between experimental and finite element findings. All the specimens' FE findings revealed behaviors that were almost identical to those seen experimentally, although with a more noticeable deviation. The influence of the elements under investigation was almost identical to the experimental data, indicating that the FE model can accurately predict the performance of rubberized concrete columns with respect to their load capacity and mode of failure (Fig. 17). Table 4 illustrates the ultimate load and displacement at ultimate load dependent on the experimental and FEM results. With error values ranging from 2.56% to 5.5% for ultimate load and from 8.9% to 1.25% for displacement at ultimate load, the findings demonstrated a high concurrence between the experimental
