## FREQUENCY DOMAIN CALCULATION METHOD FOR WIND-INDUCED RESPONSE OF MONOLAYER CABLE NET

• 摘要: 以随机振动理论为基础，采用频域法对单层索网结构风振响应进行了研究，主要探讨不同计算方法和空间相干函数的选取等问题对索网结构风振响应的影响. 依据不同的计算方法和空间相干函数，建立了3 种分析模式进行了分析. 分析结果表明：对于频率密集的索网结构，需要考虑模态交叉项对计算结果的影响；空间相干函数的选取对计算结果影响较大，采用与风频率相干的空间相干函数更为合理.

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.
