Investigating The Effective Position of Shear Walls in High Rise Building

Abstract

This paper investigates the effective positioning of shear walls in high-rise buildings design by using 9 models of G+15 story with a story height of 3m each and a plan dimension of 16m x 24m. All the models are analyzed using a dynamic response spectrum analysis in the seismic zone iv following the IS 1893-2016. The structural analysis software ETABS v16 is used to referee all the models. The findings show that the MOD9 (model 9) which is having an interior core shear wall resists more seismic forces as compared to the other configurations and it was observed that when the shear wall is placed systematically approaching the centre of the building it stiffens the building and the base shear increases. The implementation of the core at the centre reduces the displacement, inter-story drift, and time period by 36.57%, 47.05% and 53.33% respectively and stiff the building by 42.26%, 60.11% in terms of base shear and overturning moment respectively when compared with the model with no shear wall (MOD1).
