Abstract

In construction and engineering techniques, a realistic shift in architectural designs of highrise buildings can be perceived. This kind of buildings are most frequently taller and distinctive shaped
rather than normal. Predominantly, shape and orientation of the building are determined on the premises
of architectural and empirical deliberations, but the wind-induced excitations are stimulated by irregularity
of the building shapes can not be neglected also. To protect the functional necessity of high-rise flexible
buildings and to mitigate the excitations, miscellaneous methods are accessible. Between these methods,
aerodynamic modifications techniques are very influence which affect the structure of tall-buildings
significantly and have obtained a lot of awareness in recent years. For investigations of the effects of
building modification on reduction of wind load on high-rise buildings. A benchmark models can be tested
by pressure measurements. Based on the preliminary results, mean wind pressure co-efficient, base
moment co-efficient and local wind force co-efficient of the modified models are discussed to provide
comprehensive evaluations of the effects through aerodynamic modification. This paper aims a review on
various aerodynamic modification techniques applied to high-rise buildings.
