Abstract
Wind loads play the most important role in the wind-resistant design for the building with a height of 220m in Chongqing. The whole static and dynamic forces induced by wind loads must be accurately studied. Therefore, rigid model is made and high-frequency-force-balance technique is used for determining the force in the boundary layer wind tunnel. This paper gives the coefficients of aerodynamic forces under different wind direction condition and offers reference for the wind resistant design of the building.
