Abstract: Multistorey building would be the greater part influenced by quake constrains to seismic prone areas. The major concern in the design of the multi-storey building is the structure to have enough lateral stability to resist lateral forces, buckling, to control lateral drift and displacement of the building. The application of the shear wall system in Reinforced Concrete (RC) buildings has been widely used to minimize seismic consequences. Besides, the buildings with concentrated steel bracings system are used for the same reasons in steel structures buildings. Both of the systems have significance of the structural performance. Although both systems are used for same reasons, their effect shows unequal variations and behavior against seismic load. In this project, G+9 storey building, along with shear wall and bracings are being considered for the analysis. The performance of building will be evaluated on the basis of following parameters –Storey displacement, Storey drift, Base shear. In this work, the shear walls and bracings are provided at different locations with the overall analysis to be carried out using Etabs9.7 software.
