Optimum Positioning of Shear Walls in High-Rise Buildings Using STAAD Pro

Abstract

Shear wall systems are among high-rise buildings' most widely used and feasible lateral loadresisting
technologies. Their high plane stiffness and strength simultaneously support huge
horizontal and gravity loads. It is increasingly essential for multi-storey structures to include
shear walls to withstand lateral pressures like wind and seismic stresses. Therefore, it is crucial to
ascertain where shear walls will function best. Shear wall placement has to be done precisely
since anything less will work against you. The distance of the shear wall from the mass centre also
significantly impacts the shear wall's shear contribution when the hardness centre and mass centre
coincide. This project is a research to find the best possible structural arrangement for a multistorey
structure by drastically altering the placements of the shear walls. Using computer
application software called ETABS, four distinct scenarios of shear wall placement for a G+10
storey structure that maintains zero eccentricity between the mass and hardness centres have been
examined, and a frame system has been created. In compliance with IS requirements, the framed
structure is subjected to lateral and gravity loads; the results are examined to ascertain the best
location for the shear wall.
