I am modeling a flat plate on Abaqus, I need to simulate the connection between the slab and column using Macro model e.g. shell and connector element.
I used Ansys to build up my Macro-model. Here some tips on how to use it in Ansys which might be useful in Abaqus.
If you want to capture the non-linear behavior then you could use (COMBIN39) and (COMBIN14) for linear behavior which they are nonlinear and linear elements available in Ansys . For Macr-omodel you should concentrate on the critical sections and simulate them and define the force-displacement properties for each element.
