Abstract: To maintain the building's aesthetic appeal and create more open space, architects generally limit the columns width to prevent them to protrude from the walls and corners of the rooms. This challenge is common for structural design engineers, and finding a solution that is both technically sound and economically viable might be difficult. Research has shown that non-rectangular special shaped columns (SSC) can effectively address this issue, offering better structural performance compared to Conventional Rectangular Columns (CRC) including the reduction of overall deflections of the buildings. This study explores the effects of shear walls paired with specially shaped columns on the behavior of buildings with varying plan shapes and sizes. Analysis and designs for rectangular, L-shaped, T-shaped, and + shaped buildings were developed and compared. Twenty-storey building models are modeled and analyzed using ETABS software, with column sizes for L, T, and+shaped columns determined through a trial-and-error process. For comparison, the same building models are also assessed with conventional rectangular columns (CRC) and shear walls. The column sizes are selected to meet design criteria and ensure compliance with drift/deflection limits outlined in IS: 16700- 2023, IS: 456-2000, IS: 875-2015, and IS: 1893-2016. The results indicate that buildings with specially shaped columns perform better under seismic and wind loads compared to those with conventional rectangular columns. However, incorporating shear walls with specially shaped columns did not show any significant advantage. In contrast, the combination of conventional rectangular columns with shear walls offered clear benefits for the same building models. The study concludes that incorporating special shaped columns shows better performance of buildings under lateral loadings by reducing the overall deflections and drifts even without the need of the shear walls.
