Abstract
‘]
The demand for land has risen, causing scarcity and leading to a significant increase in the construction
of tall residential and commercial buildings. With limited land and a growing population, expanding
horizontally is not feasible, making multistory buildings the solution. Urbanization has led to the
construction of numerous high-rise structures, emphasizing the need for a thorough understanding and
analysis of these structures. The present study aims to determine the critical design loads for a
multistory building subjected to basic wind speeds of 55 m/s and earthquake zone classified as V, which
are considered extreme conditions for load calculations. The analysis is conducted according to the
earthquake loads specified in IS 1893:2016 and wind loads according to IS 875:1987 code. It provides
a basis for determining the principal design loads for a specific building situated in a specific wind and
earthquake zone. The analysis focuses on three high-rise structures with consistent side dimensions,
namely G+20 (60 m), G+25 (75 m), and G+30 (90 m). The study also accounts for three live load cases
(2 kN/m2
, 4 kN/m2
, and 6 kN/m2
) for all models to evaluate their impact on lateral loads. The study
compares the maximum displacements and story shears of the models. The results indicate that the
magnitude of the wind load is greater than the earthquake load with an increase in height. The story
shear of the building increases linearly in response to wind load, while the earthquake load results in
a more or less constant shear after a certain extent. The findings also suggest that the building’s
behavior is influenced by seismic loads, but the wind loads remain consistent for live load cases
considered.
