To resist the lateral loads, one of the most feasible and commonly used mechanisms are the shear wall system. Shear walls provide high plane stiffness and strength which can be utilized to resist large horizontal loads and support gravity loads simultaneously. While placing the shear walls in a building structure, a major issue is the orientation and location which plays a vital role in the seismic performance of such a system against lateral loads. If shear walls are not placed properly, they may generate eccentricity in buildings which is the main cause for torsion. In this study, attempts have been carried out to find out the proper orientation and location of shear walls in RC buildings to control drifts and deflection by modeling and analyzing buildings with different shear wall positions. For this purpose, a 10 storey RC building has been modeled in computer application software ETABS with different locations of shear walls (i.e. shear walls at center, shear walls at sides and inner walls, shear walls at the periphery, shear walls at corners, and shear walls at center and edges). The framed building structure was subjected to lateral and gravity loadings under BNBC 2020 and the analytical results of each model have been compared with that of the bare frame in terms of storey shear, storey drift, storey displacement, stiffness, torsional irregularity, and time period. Based on the results of structural analysis, it has been concluded that shear walls at the periphery are the best location to control deflection and drifts of reinforced concrete buildings. © 2021 The Authors.
