Landlord, there are no ring beams and windows in your picture. In practice, there are two ways to cut off the ring beam in the window:
The ring beam penetrates upward (or downward) along the window with a dotted line. According to the structure, additional steel bars are added at the corners.
On the other hand, the ring beam stops at the window opening, and the window opening lintel extends to both sides (each side extends to 1000 mm).
