摘要
以１８３ｍ高的某跨江输电铁塔为原型，设计制作了全塔气动弹性模型，对高耸格构式结构的风荷载及风振响应进行了风洞试验研究，获得了风振响应和风振系数等重要结果，并采用空间桁架模式，考虑风与结构耦合作用的影响，在频域中进行了随机风荷载作用下的风振响应数值计算机分析。
An experimental study was carried out on the aeroelastic model for a 183m high self supporting tower in transmission line across a river.Some valuable results such as wind load factor and wind induced response have been obtained.In addition,the numerical computation of the buffeting response was done in frequency domain based on quasi stead theory and space truss moldel.
