Shear Walls are Used in Performance-Based Seismic Assessments of High- Rise Buildings to Minimize Lateral Displacement

Abstract

The main objectives of this study are to
compare and analyze the behaviour of
structures across various time intervals, as
well as storey displacements, storey shear,
and storey drift. Each of the four variations is
based on a skyscraper with twenty stories.
The normal structure will be considered in
Model I, the floating column structure in
Model II, the shear wall structure in Model
III, and the combination of shear walls and
floating columns in Model IV. Similar static
approaches and the response spectrum are
used in seismic performance evaluations of
structures of 20 stories or higher. using
Indian Standard code IS 1893(Part1) 2002
and ETABS-2018 software. Calculations are
made for drift, shear, storey displacements,
and seismic zone IV time.
For types II, III, and IV, the storey drift was
smaller than that of a typical construction. In
model II, the storey shear about the normal
structure decreased, while in models III and
IV, it increased. Model II has a longer
floating column structure period than the
other three versions. When compared to the
other four varieties, the model III
construction performs better and has
stronger strength and smaller displacements.
