Hi, I could observe many things to be changed/improved in your model. I will mention a few for example,
1] cyclic load definition - you should not use the same displacement level both at the time series definition and at the load definition under condition tab.
2] material definition - implicit algorithm may give convergence issues, so change it to implex
3]gravity loading - 2e5 N/mm on the column seems to be too high, please check it. I reduced it approximately by dividing it by the respective length. You can put the exact value by doing a check.
4]I have also changed the modeling of the embedded rebars.
5] You should go for penalty constraint handler in case there multiple master and slave definitions at the same node, not the transformation constraint handler.
6] I also changed some your analysis settings. Please go through the model and check if it works fine for you, and you can modify it to suit your requirement.
7] I don't see the location of your control node and reaction nodes (cn and bn in the selection set of the model)
Attached is the revised model, which works without convergence issue, however, you need to modify the properties of materials and loading accordingly.
