Abstract:

In this study, the seismic performance of the concentric braced steel frames was studied in the proposed structure. In multi storied buildings, the lateral load resisting system must be of closed loops, so that it is able to transfer all the forces either vertically or horizontally. The braced frame is one which resisting lateral load system and provides high plane rigidity to the building, thereby increasing the overall stiffness of the system. The performance of the steel frame building has been investigated for five different types of bracing system such as concentric X bracing, V- bracing, inverted V- bracing, forward and backward bracings. These bracings are placed outer and inner core of the building and to compare the result of seismic analysis of high rise steel frame building with different pattern of bracing system and without bracing system. The results of the above bracing systems will be compared at different locations in the building. The performance of the building has been evaluated in terms of lateral storey displacement of X and Y direction and storey drift for unbraced and different types of braced structure by using finite element software ETABS and the results are compared to both outer and inner core. The diagonal bracing is more efficient when compared to the other bracing systems. The cost analysis for the total building was also calculated.
