Manicka Dhanasekar Popular answer

I think the question is modelling assumption related - rather than a specific tool (ANSYS). If you 'merge' concrete fill with the steel tube, you are inherently assuming the two have 'perfect' bond. You will not be able to detect delamination/ separation meaningfully.
