Abstract:

This study presents a numerical simulation of the behavior of reinforced concrete columns under eccentric loading using the finite element method. Three columns with different eccentricities were analyzed using Abaqus software. The results were compared with laboratory experiments to validate the accuracy of the simulations. The analysis focused on the concrete damage and cracks, force-displacement curves, and bearing and ultimate capacity of the columns. The results showed that as the eccentricity increased, the bearing capacity of the columns decreased, and the bending behavior of the columns became more pronounced. Todeschini’s behavioral model was found to accurately predict the behavior of the columns when the eccentricity was low but less accurate at high eccentricity values. These findings have important implications for designing and analysing reinforced concrete columns under eccentric loading.
