Bracing systems play a critical role in enhancing the stability and load-carrying capacity of reinforced concrete (RC) frames, particularly under lateral and compressive loading that may lead to buckling. This review examines the effectiveness of various bracing configurations—such as diagonal, X-bracing, K-bracing, knee bracing, and concrete–steel composite bracing—in improving the buckling resistance of RC structures. Emphasis is placed on understanding how bracing layout, stiffness, material properties, and connection detailing influence the global and local stability of RC frames. The study synthesizes findings from experimental investigations, analytical modeling, and numerical simulations to provide insights into optimal bracing strategies for mitigating buckling and improving overall structural performance. The review concludes that well-designed bracing systems significantly enhance the ductility, stiffness, and energy-dissipation capacity of RC frames, making them a valuable technique for strengthening existing structures and improving the reliability of new construction.
