Abstract

In India high rise buildings are becoming a common feature of urban landscape. Limited information is available regarding wind flow around such buildings. Effect of wind is predominant on structure depending on location, orientation of building. The flow is affected by architectural features. In this work a rectangular building is studied under the effect of wind force and how orientation affects the wind load on tall buildings shall be studied based on wind tunnel tests with rigid models, Wind pressure distributions on building with different aspect ratio will be measured and analyzed. The investigations can offer some basic understanding for estimating wind load distribution on building and facilitate wind resistant design of cladding components and their connections considering wind load. It is also proposed to study the interference when two tall buildings are built side by side. The study will involve different orientations and separating distance between the two tall buildings. Models will be tested in wind tunnel for different angles of orientation and different wind speeds.
