The rapid increase in population, industrialization, land cost, and land availability, the necessity for a multi-storey building is escalating by the day, however high-rise buildings are heavily influenced by lateral loads. On increasing the height the lateral forces increase, making it necessary to improve the lateral resisting capacity of multi-story buildings. The Bracing system may be one of the greatest ways to resist these lateral loads. The bracing mechanism is often used to effectively control displacement and storey drift. The bracing system's mechanism is similar to that of a truss, and it controls lateral deflection. The main problem in multi-story steel building design is to have a good lateral load resisting system in addition to the gravity load system because it also influences the design. Any construction is designed to withstand a variety of loads. Dead and live loads occur vertically downward and so effectively support the building, when the structure is not only subjected to vertical forces but might also is subjected to horizontal forces owing to Earthquake, wind load, and other factors. Because of these horizontal stresses, the structure is prone to overturning or twisting. These horizontal pressures are inherently dynamic. Bracing is important in resisting horizontal forces. As a result, the impact of wind on the structure is assessed. Four distinct types of bracing systems are used in this investigation. Most commonly x and v bracing are utilized along with mixed diagonal bracing are also used. Mega cross bracing is also employed. The impact of wind forces on the models is investigated. In this study, the structural performance is evaluated using the ETAB 2018 software programme. The results of various assessments indicate which type of bracing is best suited for certain heights.
