Tall buildings are going up all over the world, so it increases the importance of design for wind-induced
building motion. Tall structures that comply with lateral drift requirements specified in building codes
can still experience significant swaying under strong wind conditions. Severe wind-related disasters in
India and the United States have highlighted the fact that many existing buildings are not entirely wind-resistant. This underscores the need to reevaluate and enhance the computational techniques currently
used to determine along-wind loads. This paper examines methods for calculating wind load using the
gust factor method. The analysis focuses on a G+17 RCC high-rise building, considering the effects of
wind load on its structural integrity. By employing the gust factor method, this study aims to provide a
comprehensive understanding of wind load impacts and improve the design and resilience of high-rise
buildings against strong winds. change in zones 3 and 5 and terrain categories 3 and 4 and analyzed
for story drift ratio, bending moment, shear force, gust factor, and gust pressure as per the unrevised
and revised code by using ETABS-2016. Results are plotted graphically to study the pattern of variation
in story drift ratio, bending moment, shear force, gust factor, and gust pressure. Comparisons are made
with results obtained from the software, and it was observed that the IS: 875 Part 3-2015 gives more
sensitive and accurate values as compared to the IS: 875 Part 3-1987 and the value is approximately
30% to 40% higher for the revised code.
