Abstract
The study examines how well step-back set-back structures perform seismically when they are resting
on a 27° slope in terms of base shear, maximum story displacement, story drift, and time period. Shear
walls 200 mm thick are positioned at various points. The seismic performance of the square plan
structure having shear wall at corner locations is presented in this study. The study’s findings indicate
that the shear wall’s position affects the forces that are attracted, so it must be in the right place. The
displacement of the top story in entirely structures without a shear wall is maximal in both the X and Y
directions. The average displacement reduction is 36% in the X direction and 40% in the Y direction
as long as we supply shear walls. The eighth story is where the story drift reaches its maximum, and
the average percentage reduction in the X and Y directions is 74% and 65%, respectively. The structure
with a shear wall configuration experiences, on average, 24% more base shear than the structure
without a shear wall. Shear walls have an impact on the structure’s overall performance, which
emphasizes how crucial they are for improving seismic resilience. From above, it is clear that the stepback set-back structure with its six steps from the top has less top story displacement, story drift, and
time period than a regular structure.
