I suggest that you use ACP pre and pro for this simulation and define the composite material in this module. After you are done with this part of your analysis you can define the concrete in Mechanical which is going to be incontact with CFRP. I attached a PDF file that explain both method of modelling directly in workbench as well as ACP pre and pro.
Thank you very much for your interaction...I have recently found that I have to simulate the joint overall models...Im sorry to request again of there is any reference for ANSYS in joint...actually I am facing not converging problem because I have a cantilever beam in my model. "Solution not converged at time..."
If you are modeling concrete using SOLID65 legacy element then there will be high probability of solution non convergence if cracking and crushing are activated. Also this element is highly sensitive to the mesh size used, you can deactivate cracking and crushing of the element by setting them values of (-1) and then solve just to see if this is the reason behind non convergence. In general it's tricky to get SOLID65 element to converge with both cracking and crushing activated, the load (displacement controlled) should be applied at a very slow rate with a fine mesh. You can try the newly developed Microplane model using SOLID185 with damage elasticity/plasticity or with CPT215 coupled damage plasticity.
There are numerous references online on simulation of beam column joint
