结合一中跨跨度为 96 0m的悬索桥施工猫道的抗风稳定性研究 ,提出了通过节段模型静力 3分力试验以获得静力 3分力系数 ,进而进行猫道静力稳定性的非线性计算分析的方法 ,同时进行了全模型风洞试验。比较非线性计算结果和全模型试验结果可知 ,该方法能有效地对猫道结构进行抗风稳定性评估 Based on the study of the wind stability of a catwalk with a span of 96 0 m, the 3-point static force test of the section model is proposed to obtain the static 3-component force coefficient and then the static stability of the catwalk Nonlinear calculation and analysis methods, while the full model wind tunnel test. Comparing the results of non-linear calculation and the results of full-model test, we can know that this method can effectively evaluate the wind-induced stability of the catwalk structure
