The ring beam in the masonry structure should be closed, which can improve the integrity of the structure and is very beneficial to earthquake resistance.
In the filling wall of the frame, the wall is generally built to the bottom of the beam, and there is no other ring beam, but the lintel of the top of the door and window is more.
Because the load-bearing system of the frame structure is the frame, not the wall, so even if there is a need to set the ring beam does not need to be closed.
