In recent years, the devastating earthquakes that occurred in many parts of the world have made it even more important the design of earthquake-resistant structures and earthquake performance assessment of existing structures. When innovative systems are examined in building design, it is seen that depending on the developments in recent years, performance-based designs come to the fore in addition to force-based design. This paper provides a new design method’s model for multi-storey buildings that can achieve the same resistance against seismic movements by using less concrete and reinforcement using the SAP2000. Modeling studies of the braced frame system used in steel structures for reinforced concrete and multi-storey buildings with different heights was carried out according to 2019 Turkey Building Earthquake Code (TBEC) and Turkish Standard 498 (TS 498). In the modeling studies carried out in reinforced concrete and 20, 30 and 40 storey buildings, the same strength was tried to be obtained with less concrete and reinforcement. As a result of the studies, it has been seen that this new system, which is determined for all models, is an advantageous and performance system in terms of both volume, weight and stabilization compared to reinforced concrete structures with shear wall frame system.
