Modern tall buildings having multiplex functions are increasing in height for the powerful use of land by the development of construction skills, the progress of structural analysis techniques, the concentration of population, and industrial and economic development of modern society. Wind-induced vibration of tall buildings are mainly due to buffeting, vortex and wake. Also, wind-induced responses of buildings are different according to the geometry of buildings, structural characteristics such as stiffness, mass and damping, and turbulent characteristics of wind. In this paper, wind-tunnel experiments are performed using variables such as the plane and elevation shapes and aerodynamic apparatus of buildings. The square, equilateral triangular and circular sections were selected as plane shapes of buildings, and the setback and tapered types were tried for the circular section. Also, wind-induced responses were investigated for a total of nine models having equivalent effective slenderness ratios by attaching ribs and spirals to the circular model, the setback type model, and the tapered type model. From the results of the experiments, wind-induced response was the least for the circular section, and the wind-induced response for the setback type was much smaller than that of the tapered type. The ribs and spirals as aerodynamic apparatus had the similar damping effects in the cross-wind direction.
