Analysis of the structural performance of CES columns under axial compression using FEM

Concrete-Encased Steel (CES) columns have become a vital element in modern construction due to their superior load-bearing capacity and stiffness. This study investigates the behavior of CES columns subjected to axially compressive loading. The research involves the simulation of experimental models using concrete with various strengths using Finite Element Modeling (FEM). Additionally, a comparative analysis is conducted between CES columns reinforced with fibers and those utilizing conventional concrete. The research results reveal a significant enhancement in compressive load-bearing capacity with the increase in concrete strength and the incorporation of fibers. These findings offer a deeper understanding of the behavior of CES columns using various concrete strengths, contributing valuable insights for the design and optimization of these structural components.
