during earthquake most of the structure fail due to weak structural design or lack of structural detailing. So there is need of modified building frame which will withstand during natural calamities. In this paper, a Comparative study of high rise steel frame with and without bracing have been carried out on symmetrical plan by considering the gravity loads and lateral load in the form of Earth quake load . A setup of different type of bracing system is introduced to reduce lateral load on structural element. In this study a G+30 Steel frame structure is analysed for zone III as per IS 1893:2002 using STAAD.Pro. The main Parameter considers in this paper to compare the seismic analysis of Steel Structure are Base Shear, Story Displacement, and Time Factor. From the table values it shows that due to bracings in both directions, base shear increases. The displacements at roof level of the building with different bracing style will reduce. Modal time period is also reducing the bracing shows highly effective and economical design of bracing style.
