摘　　要：采用线性滤波法,根据Davenport风速谱,得出塔架的脉动风速时程曲线及功率谱曲线;建立简化模型,对单管塔和组合塔架进行脉动风时程分析,得出塔架的脉动风振响应。采用阵风荷载因子法,对风振分析结果进行处理,得到塔架的位移风振系数及荷载风振系数。According to Davenport wind spectrum, the pulsate wind velocity-time history curves and power spectrum curves correlation are simulated by linear filtering method. The wind-induced vibration response analysis of single-tube tower and concrete filled double skin steel tube （CFDST） tower are conducted with simplified models. The wind-induced vibration coefficient due to displacement and wind vibration coefficient due to load are got by processing the results of wind-induced vibration analysis through gust loading factor method.
