Abstract
Based on the random vibration theory, the frequency domain calculation method is adopted to analyze the wind-induced response of monolayer cable net. Some parameters crucial to the response of wind vibration are highlighted, including different algorithm of frequency domain calculation and the selected spatial coherence function. Three analysis patterns of monolayer cable net were established to analyze effect of parameters. The results shown that the coupling effect between modes is significant; the selected coherence function has a great impact on the computation, the coherence function related to wind frequency is more reasonable.
