| Abstract: | Due to the increased slenderness and low damping,high-rise buildings are sensitive with wind loading.Aerodynamic modification is an effective method to minimize the displacement and vibration of high-rise buildings with low cost.In this paper,different modifications are discussed.Depending on the building features,the modification methods against wind excitation are divided into:selecting efficient building shapes,changing cross section along the height and local feature adjustments.Advantages and disadvant... |
