摘　　要：鉴于传统输电塔结构造型单一,针对兼顾结构美观性与周围环境协调性新型景观输电塔,采用AR模型模拟20 km/h的风速时程作用下进行风振响应分析,并把风振系数理论计算值与规范计算值进行了比较。结果表明:随着高度增加,输电塔风振系数基于软件SAP2000实际计算值与规范计算值相差较大,建议风振系数值采用理论计算值。In view of the single structure of the traditional power transmission tower,this paper aims at the new landscape power transmission tower that takes into account the aesthetics of the structure and the coordination of the surrounding environment.The AR model is used to simulate the wind vibration response of 20 wind speed and time history,and the wind vibration coefficient is theoretically calculated.The value is compared with the standard calculated value.The results show that as the height increases,the actual calculated value of the wind-vibration coefficient of the transmission tower based on the software SAP2000 differs greatly from the standard calculated value.It is recommended that the theoretically calculated value of the wind-vibration coefficient is used.
