Introducing a diamond cable bracing with rings for steel frames

Cable bracing has many advantages, such as high tensile strength and lack of buckling in evaluation with traditional braces, the use of a cable as a brace is necessary. The aim of the present research is the use of cable bracing with a new configuration so that all cables remain in tension. For this purpose, a diamond cable bracing system for steel Structures was proposed. Sap2000 software was used to model the cables and rings. It was found that the proposed system eliminated the main weakness of the x-shaped cable bracing system. Ability to install for existing structures, easy installation, and repair, lightweight and delicate dimensions are the capabilities of this type of bracing, which makes its use in the field of reinforcement significant. Increasing or reducing the diameter of the cables can control the amount of displacement.  Among the studied models, MRF has the least amount of axial force applied to the beams. By adding steel cable braces to the frame, a large amount of axial force is added to the floor beams. In this case, by increasing the diameter of the cables, the amount of this force can be reduced.
