Wind Excited Action around Tall Building Having Different Corner Configurations by Rahul Kumar Meena, Ritu Raj, S. Anbukumar

“…Wind effects on building shapes having different corners change the characteristics of the separated shear layer and reduce the downstream wake which helps to reduce drag and lift forces simultaneously. Recent study shows that the windward pressure distribution pattern is almost independent of building size and height. …”
