The project delved into the analysis of the Concrete-Filled Steel Tube (CFST) composite columns, which were subjected to a uni-axial eccentric compressive load. The column curves, strain, load-axial displacement curves, and Finite Element Analysis (FEA) are used for the evaluation .To provide a comprehensive comparison, two models of CFST columns with connecting plates were created, one is made by corrugated steel and the other using regular steel. In addition with an FRP plate was introduced to enable a thorough assessment. The ANSYS2021R2 program was utilized to produce the column connecting plates and its modeling. To compare the load-axial displacement curves got from the FEA models with those from the tests and evaluating the failure mechanisms. The results obtained from the FEA simulations of the double-plate linked Uni-axial eccentric compression performance of the CFST composite columns aligned remarkably with the test findings. Moreover, the study involved comparing various forms of double-plate linked CFST Columns with two mechanical characteristics to those of L-shape, T shape, Cross shape double plate connected CFST Column filled with concrete. The FEA results were also evaluated against the computed N-M correlation curves. By a rigorous assessment of the CFST composite columns, which involved a thorough evaluation of their load-axial displacement curves, strain, column curves, and FEA. By providing a detailed comparison of the double-plate linked CFST columns with different mechanical characteristics, this study provides a critical recommendations for engineering design.
