| Abstract: | This paper introduces the stiffness matrix of cable roof structures, the characteristics of the random wind excitations which are filtered white noises, and the method of how to generate a filtered white noise vector with spatial correlation using a white noise process. It also analyzes the wind induced random response of the cable roof structures using the discrete analysis method for random vibrations. Based on the numerical results, the variation of the wind induced random response with its parameters is discussed. |
