Earthquake is one of the destructive natural phenomena that has left a lot of human an‎d financial losses in the last half century alone, an‎d considering the earthquake-proneness of our country an‎d its location on the Himalayan Alpine belt, it is necessary to use more methods Dealing with this phenomenon, including structural systems against earthquakes. Concrete structures are one of the most common structural forms in the design of structures. Bending frames are generally used to deal with the lateral force an‎d sometimes to distribute the axial forces between the main an‎d secondary columns. In recent decades, a variety of dual systems have been invented an‎d recommended, each of which has specific advantages an‎d disadvantages. The vibration behavior of conventional concrete flexural frames has various problems. Among these problems, we can mention the low plasticity an‎d incomplete hysteresis curve of these structures an‎d their low performance level. In this research, the use of non-buckling braces in concrete bending frames is proposed as a new generation of bracing, an‎d the results showed that the lateral displacement in concrete buildings with buckling braces is reduced, an‎d this indicates the positive effect of these braces in reducing the lateral displacement of concrete frames.
