Abstract- It is well-established fact that shear walls are quite effective in lateral load resistance of low-rise to
medium-rise reinforced concrete buildings. Restriction in the architectural design by the presence of the shear
walls may contribute to discourage the engineers from adopting the shear walls. Due to this a new concept of
providing storey deep and bay wide discrete staggered shear wall panels have been introduced.
In this study, the effect of various configurations of shear walls on high-rise structure is analysed. The drift
and inter-storey drift of the structure in the following configurations of shear wall panels is studied and is
compared with that of bare frame: (1) Conventional shear walls. (2) Alternate arrangement of shear walls. (3)
Diagonal arrangement of shear walls. (4) Zigzag arrangement of shear walls. (5) Influence of lift core walls.
Of the configurations studied, the zigzag shear wall configuration is found to be better than the other systems
studied in controlling the response to earthquake loading. The diagonal configuration is found to be having
significant role in controlling the response of structures to earthquake.
