Abstract
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.
