Yes, it's ok for the beam, but here is the case of the reinforced concrete column and steel column union. I'll make an example tonight and see. It would be better if the command, which is active when the combination command is entered for the combination of reinforced concrete column-steel beam, intersect according to the connection element in the vertical (z direction) reinforced concrete column is opened. Otherwise, the solution you mentioned is the most ideal, but in practice it is mostly done as I said. At least in my area, the connection element is placed on the column according to the beam slope. The concrete of the column is poured obliquely or the grout concrete is poured.
