Abstract:In the wind tunnel test of the rigid model for Wuxi Lihu Technology Building,the average and fluctuating wind pressure on the model surface are measured. The coefficients of the average wind pressure and the shape coefficient of wind load at each monitoring points under different wind angles and the shape coefficient of wind load at each floor are achieved in the test. The influence of wind field and wind angle on the coefficients of the average wind pressure and shape coefficient,as well as the aerodynamic interaction between two square section towers are discussed. The feasibility of the application of the shape coefficient of wind load on the structure design are analysed. It was concluded that the shape coefficient of the one of double towers is greater than that of the single tower.

Keywords:double tower tall building; wind tunnel test; wind pressure coefficient; shape coefficient of wind load
