In masonry buildings, closed reinforced concrete beams are set in the masonry along the horizontal direction to improve the spatial stiffness of the building, increase the integrity of the building, improve the shear and tensile strength of the masonry building, and prevent the building from being damaged by uneven settlement of the foundation, earthquake or other large vibration loads. The continuous reinforced concrete beam on the upper part of the building foundation is called the foundation ring beam (also called the ground fixed beam), while on the upper part of the wall, the reinforced concrete beam close to the floor is called the upper ring beam.

Because the ring beam is a continuous closed beam, it is called a ring beam. Increase the integrity of the building.
