Abstract:

The development of high strength concrete, higher grade steel, new construction techniques and advanced computational technique has resulted in the emergence of a new generation of tall structures that are flexible, low in damping, slender and light in weight. These types of flexible structures are very sensitive to dynamic wind loads and adversely affect the serviceability and occupant comfort. Thus, aerodynamic modification has become an important aspect of tall building design process. Various aerodynamic modifications on building could be made in order to improve the aerodynamic performance. To ensure the functional performance of tall flexible structures and to control the wind induced motion of the tall buildings various types of aerodynamic modifications to the shape/geometry of the buildings are possible. The purpose of the present work is to investigate the effect of height to width ratio of tapered shape tall building on wind pressure coefficient distribution around different surface of building models. For the present study height to width ratio 3, 3.5, 4, 4.5 and 5 are taken to study the wind pressure coefficient variation along height. The results show that height to width ratio has significant effect on wind pressure coefficient distribution around building.
