Abstract

In the recent past, many tall buildings are being built in India. The effect of wind loads (WL) becomes predominant
for the design of tall buildings. Several failures of structures have occurred in India due to wind. The IS 875 Part-
3 deals with WLs on different types of structures. This study presents the wind effects on windward and leeward
column columns of buildings with different aspect ratio and height of building. The models are categorized
based on number of stories and aspect ratio of the building. The effect of WL on gravity load is studied. All the
frame models are idealized as three-dimensional models, and analyzed using the software ETABS. The variations
of bending moment and axial force in windward and leeward columns are considered to study the behavior of
frames. From the study, it is concluded that leeward column are vulnerable compared to windward column.
