Simulation of Proposed Concrete Filled Steel Tube Connections under Reversed Cyclic Loading in Abaqus

In this tutorial, Simulation of Proposed Concrete Filled Steel Tube Connections under Reversed Cyclic Loading in Abaqus has been studied. Composite steel-concrete structures are used in civil engineering projects worldwide. In recent decades, concrete-filled steel tube (CFT) structures have become accepted and used in buildings that they can provide the enhanced advantages of ductility associated with steel structures and concrete components. The advantages of CFT columns over other steel-concrete composite structures called either mixed or hybrid systems include the fact that inside concrete prevents local buckling of the steel tube wall and that the steel tube extends the ability of concrete spalling. Although the CFT can be an economical form of composite construction, their use has been limited due to the complexity of the beam-to-column connections and the limited construction experience

The steel column and beams are modeled as a three-dimensional shell part. The concrete is modeled as a three dimensional solid part. You can see a figure of the assembled parts at below

The steel material is modeled as a elastic-plastic material with ductile damage criterion to predict damage initiation and propagation during cyclic loading. The concrete material is modeled as an elastic material with the Concrete Damage Plasticity model to predict tensile damage during the analysis. The general static step with a specific time period is selected. The contact beam and column and steel column with concrete are assumed as perfect contact. The fixed boundary condition is assigned to the top and bottom surfaces of the column and displacement in the reverse direction are assigned to the two beams. The mesh for all parts should be fine especially near the contact zone

After the simulation all results such as stress, damage, tensile damage, strain, force-displacement diagram,….can be achievable. You can see some figures for the result below
