Abstract:

Based on the random vibration theory, the frequency domain calculation method is adopted to analyze the wind-induced response of a monolayer cable net. Some parameters crucial to the response of the wind vibration are highlighted, and different algorithms for the frequency domain calculation and the selected spatial coherence functions are discussed. According to the different algorithms and spatial coherences, three analysis patterns of the monolayer cable net are established to analyze the effect of the parameters. The results show that the coupling effect between different modes is significant; the selected coherence function greatly affects the computation, and the coherence function related to the wind frequency is more reasonable.
