Columns are one of the most critical components in any structural system, as they serve as primary load-bearing elements that support vertical and lateral forces. The performance and reliability of a structure heavily depend on the efficiency of its columns in transferring loads safely to the foundation. Despite their fundamental role, a major challenge in structural engineering lies in identifying and optimizing the most suitable column shapes that can carry the highest loads under relatively simple and practical conditions, while ensuring structural integrity and material efficiency. This study aims to explore and analyze a variety of column cross-sectional shapes to determine their mechanical behavior and structural performance under different load scenarios. The research focuses on comparing conventional reinforced concrete columns with specially shaped columns such as L-shaped and T-shaped sections that are proposed as viable alternatives for improving performance and material usage. The investigation involves finite element analysis (FEA) using the ANSYS simulation software to assess the structural behavior of different column geometries. The methodology consists of two main analytical stages. In the first stage, a lateral load analysis is conducted to measure the displacement response of each column shape under horizontal forces, simulating real-world conditions such as wind or seismic activity. The second stage involves modal analysis, which evaluates the dynamic behavior of the columns by examining their vibration characteristics, specifically the natural frequencies and mode shapes. Results from the simulations indicate that specially designed concrete columns with non-traditional cross-sections exhibit enhanced performance compared to standard rectangular or square columns. These special-shaped columns demonstrate reduced lateral displacements and improved dynamic responses, making them effective alternatives in scenarios requiring higher stability and resilience. Moreover, the modal analysis using the mode-superposition technique reveals that the special-shaped columns possess distinct vibrational properties, which can be strategically used in displacement-based design approaches. In conclusion, the findings suggest that alternative column shapes, particularly L-shaped and T-shaped sections, can function as effective replacements or succedanea for traditional designs, offering superior structural behaviour under both static and dynamic loads. This research provides valuable insights for structural engineers aiming to optimize column design for enhanced safety, efficiency, and performance in modern building construction.
