In this tutorial, the simulation elliptical ultra-high-performance concrete-filled steel tabular column under compression load in Abaqus has been investigated. Elliptical concrete-filled steel tubular (CFST) columns have recently attracted significant attention because of their increased strength and stiffness compared with empty elliptical hollow sections. The UHPC core is modeled as a three-dimensional solid part. The steel part is modeled as a three-dimensional shell. You can see a figure of the assembled parts below
Concrete-filled steel tubular (CFST) columns are frequently chosen as building members, bridge piers, transmission towers and offshore structural elements owing to their high strength, stiffness, ductility, and energy absorption capacity. Circular or rectangular steel tubes are filled with concrete to form these composite columns. Elliptical CFST columns, a new form of composite columns, are made by filling concrete into the elliptical hollow steel tubular column. The Concrete Damaged Plasticity is used to model UHPC behavior. The data are extracted from the reference paper. The steel material is modeled as an elastic-plastic material with ductile damage criterion. The general static step with some changes in the convergence model is implied. The ideal or perfect contact between the steel tube and concrete is used. The general contact with contact property is considered among all parts. The fixed boundary condition is used for the bottom rigid body and displacement with amplitude for the top rigid body. The mesh should be fine to obtain good results
After the analysis, all results such as stress, strain, damage, force-displacement diagram,…. are achievable. You can see some figures for the results below
