It appears that you have misunderstood the point about available length of residual bar that can serve the demand of negative moment. You do not have 990mm. I have already addressed that: You can provide extra rebars as per details shown by Ayesha. It is what it is! You cannot avoid them. What you can do is to limit their width so that the structure can have an longer service life, and the rebars remain corrosion free. I hope you understand that main/non-main depends on whether there is one-way or two-way action.
