Abstract
Abstract The ubiquitous stone column used in building construction in the ancient world was often fluted, it had parallel vertical grooves or channels cut into its surface. In this research, forty-two columns with different types of flutes and thickness were tested and their behaviour was studied. A Finite Element Analysis (FEA) model was developed to perform analysis of fluted columns subjected to compression. The cases with a different number of flutes such as 3, 4, and 5 respectively and with varying thickness of steel sheets 0.6 mm, 0.8 mm, 1 mm 1.2 mm, 1.4 mm, 1.6 mm, and 1.8 mm have been considered in this study. From the analytical investigation results it is understood that the increased number of flutes in columns directly effects on the load-carrying capacity of columns with five numbers of flutes having the highest load-carrying capacity, the lowest stress levels and less deflection relative to columns containing lesser number of flutes. The application of various thicknesses of column often has a strong impact on the ability to bear the load. The column with D/t of 88.88 exhibits greater load capacity, stress reduction, and lower deformation values compared to rest of column with different thickness.
