This paper studied the composite action of concrete-filled circular aluminum alloy tubular (CFCAT) stub columns under axial compression. A fine-meshed finite three-dimensional (3D) solid element model making use a tri-axial plastic-damage constitutive concrete and elastoplastic was established. parametric study utilizing verified (FE) carried out analytical results were exploited to investigate actions subjected Compared with steel tube (CFCST) columns, exerted weaker constraint effect on...
The mechanical behaviors of recycled aggregate concrete (RAC) are upgraded by outer steel tube confinement, and the performance concrete-filled tubular (RACFST) columns is similar to that traditional (CFST) columns. purpose this study investigate rectangular (RACFRST) stub under axial loading. Three-dimensional finite element (FE) models were established, which utilized a triaxial plastic-damage constitutive RAC model considering replacement ratio aggregates. analysis results indicated...
Recycled aggregate concrete-filled steel tubular (RACFST) columns are widely recognized as efficient structural members that can reduce the environmental impact of building industry and improve mechanical behavior recycled concrete (RAC). The objective this study is to investigate circular (RACFCST) stub subjected axial loading. Three-dimensional finite element (FE) models were established using a triaxial plastic-damage constitutive model RAC considering replacement ratio aggregates. FE...
This paper presents a numerical investigation of lightweight aggregate concrete-filled circular steel tubular (LACFCST) stub columns under axial compression. A finite 3D solid element model the LACFCST column was established by adopting plastic-damage constitutive concrete (LAC). The (FEM) analysis results revealed that confinement effect tube on infilled LAC weaker than conventional concrete. parametric study making use 95 full-scale FEMs conducted to investigate influences various design...
