Abstract

The Finite Element Method (FEM) has expanded in usage and popularity in recent years. It is now one of the fundamental techniques for analyzing how elements of reinforced structures behave. Because of its benefits over the majority of other numerical approaches, the Finite Element Analysis (FEA) method has proven to be a particularly strong tool in engineering analysis. The purpose of the research is to compare the practical results experimental studied and the theoretical results from the ANSES program. This study examined the behavior of columns until failure using the ANSYS 19 program and the finite element approach. To lower the column's weight and, consequently, the loads on the soil during foundation design, this research aims to create lightweight concrete box columns using various base materials at a lower cost. The ANSYS 19 program is used to explore finite element (FE) modelling. Eleven square short column specimens with side lengths of 200 mm, heights of 1000 mm, and basic box dimensions of 100 × 100 mm along the height of the column were modelled for this study. Axial and eccentric loads were applied to the samples until collapse happened. Previous research's experimental results were used to validate the finite element models used in this investigation. The ratio between the vertical displacements of the experimental and analytical findings ranged from 5.1% to 19.34%, and the ratio between the experimental and analytical ultimate loads ranged from 0.68 to 4.19%. The horizontality of the experimental and analytical results ranged from 3.83% to 21.27% in the displacement ratio.
