Abstract: This study presents a numerical analysis of the seismic response of tubular steel columns with circular and square cross-sections. The analysis focuses on three dimensional models for each cross-sectional type: 300 mm, 400 mm, and 500 mm in diameter or width, with corresponding wall thicknesses of 6 mm, 8 mm, and 10 mm, respectively. Using Finite Element Analysis (FEA) seismostruct, the study investigates the behaviour of these columns under seismic loading, examining the impact of cross-sectional shape, dimensions, and boundary conditions on their structural performance. The results highlight critical factors affecting seismic resilience and provide recommendations for optimizing the design of tubular steel columns.
