Finite Element Analysis on Mechanical Performance of Concrete-Filled Steel Tubular Latticed Column with Initial Stress
A finite element method (FEM), which implements ANSYS to analyze the performance of concrete-filled steel tubular (CFST) latticed column with initial stress, was presented. Studies showed that the FEM results agreed well with the test results. The full loading process of the CFST latticed column subjected to axial load was analyzed by combining FEM with two parameters of initial stress degree and slenderness ratio. Research results indicated that the initial stress in the steel tube of the CFST latticed column advances and elongates the elastic-plastic phase of the specimens and postpones the occurrence of ultimate load bearing capacity and relevant displacement. Furthermore, the ultimate load exhibits a significant decrease of up to 12% for long columns with large ISD, but not for short columns.
