Steel structures provide better resistance against lateral and various other combinations of loads. Steel structures have various advantages over RCC structures as they have high strength to weight ratio, uniformity, elasticity flexibility and take minimum time for erection (as large prefabricated structures are available). Steel is recyclable too. Bracing systems are well known to increase the stiffness of any type of structure. Using bracing system in steel structures increases the stiffness of the structures to a large extent. In present paper, the evaluation of different kinds of curved bracing system was carried out for steel framed structure while performing dynamic seismic analysis as per IS:1893:2016. The behavior and performance of various shaped of curved bracing was analyzed in software staad.pro and results were collected and represented in the form of tables, graphs and figures. For this purpose, 14 storey regular building was chosen and different geometric and design parameters were taken as per the codal provisions. The height of each floor was considered as 3.6m. Whereas, the plan of the building entails 6 x 6 bays in both the direction and the size of each panel was taken as 5 x 5m. After scrutinizing the results gathered, it can be concluded that ‘AV Arc’ bracing system is the most effective bracing system and it can be used effectively to resist lateral loads such as earthquake loads.
