it is difficoult to understand which is the problem you are facing and why Link180 is not working in you model.
If you are new to model reinforced concrete elements in ANSYS, I suggest to follow this video https://www.youtube.com/watch?v=h2BApwflt3E&t=417s . It explains very well how to model concrete with solid65 and rebars with link180 with an example. Maybe, by comparison, you can find which is the problem with your model.
