In this tutorial, the Simulation Ultra-high-Performance circular short CFST column in Abaqus under compression test has been investigated.The concrete core is modeled as a three-dimensional solid part. The steel tube is modeled as a three-dimensional shell part. You can see a figure of the assembled parts below
CFST columns are considered as an economical option for the composite structural members since most of the concentrically compressive force is carried out by the concrete which is cheaper than the steel. Accordingly, further economies could be obtained by utilizing UHPC in CFST columns. The use of UHPC in CFST columns considerably decreases the cross-sectional size, and thus saves the work space area. However, the use of UHPC in CFST columns significantly reduces their ductility. The Concrete Damaged Plasticity model is used to define UHPC behavior. The elastic-plastic material with ductile damage criterion is used to mode steel tube behavior under compression load. The general static step with some changes in the convergence model is selected. The general contact capability with contact property is assumed to consider all contact in the contact domain. The surface to surface contact with contact property or perfect(Ideal) contact can be used to define the interaction between steel tube and concrete core. The fixed boundary condition is assigned to the bottom rigid body and displacement to the upper one. The mesh should be fine to obtain a good result
After the simulation, all results such as stress, strain, failure, force-displacement diagram, and … are available. You can see some figures for the results below
