Nonlinear wind-resistant design method for cable net façades

Cable net façades are sensitive to the fluctuating wind loads due to their high flexibility, light weight, and small damping. Since the cable net façade is a new kind of structure with obvious geometrically nonlinear behavior, there is no proper corresponding wind-resistant design method. In this paper, first, the nonlinear random vibration theory is used to determine the wind-induced nonlinear response formulation of the cable net façade. Then, a nonlinear wind-resistant design method for the cable net façade is developed based on the structural response. Finally, the accuracy of this wind-resistant method is verified, and the scope of the application is discussed.
