Simulation Behavior of thin-walled dodecagonal section double skin concrete-filled steel tubular beam-columns in Abaqus

In this tutorial, Simulation Behavior of thin-walled dodecagonal section double skin concrete-filled steel tubular beam-columns in Abaqus had been studied. The steel sections are modeled as a three-dimensional shell part and the concrete is modeled as a three-dimensional solid part. You can see a figure of the assembled parts at below

The use of concrete-filled steel tubes (CFST) is growing because of their superior performance. A creative innovation of composite construction is known as concrete-filled double skin steel tubes (CFDST) which were introduced and have been studied by many researchers. CFDSTs are composite members which consist of an inner and outer steel skin with the annulus between the skins filled with concrete. CFDSTs also hold the characteristics of concrete-filled steel tubes (CFST) and have less self-weight. This kind of composite columns has been recognized to have a series of advantages, such as high strength and bending stiffness, good seismic and fire performance

In this tutorial two analysis is performed. First, static stimulation and second dynamic explicit simulation. The perfect contact between concrete and steel profiles is assumed. The surface to surface contact with friction coefficient, shear limit, and elastic slip can be used. The general contact interaction for all parts in the contact domain is used. The displacement load control is used to model load and fixed boundary conditions are assigned to the bottom rigid plate. The mesh should be fine to predict damage in all parts. To define concrete material, the CDP model and for stell elastic-plastic model are used. After the simulation, all results, especially the force-displacement diagram, and damage can be available.  You can see some figure for the result below
