中文摘要：
在这篇论文，评估 along-wind-induced 的一个分析框架一个传播塔的动态回答被介绍。二个分析模型和一个新方法被开发：(1 ) 一个更高的模式概括了力量光谱(GFS ) 传播塔的模型被推出；(2 ) 包括更高的模式的贡献的一个分析模型进一步作为一个合理代数学的公式被导出估计结构的排水量反应；并且(3 ) 一条新途径，与排水量(ALD ) 使用负担而不是力量，塔被给解决传播的内部力量。不同于常规方法， ALD 方法能避免计算相等的静态的风负担(ESWL ) 。最后，传播塔结构被用作一个数字例子验证 ALD 方法的可行性和精确性。
英文摘要：
In this paper, an analytical framework to evaluate the along-wind-induced dynamic responses of a transmission tower is presented. Two analytical models and a new method are developed： （1） a higher mode generalized force spectrum （GFS） model of the transmission tower is deduced; （2） an analytical model that includes the contributions of the higher modes is further derived as a rational algebraic formula to estimate the structural displacement response; and （3） a new approach, applying load with displacement （ALD） instead of force, to solve the internal force of transmission tower is given. Unlike conventional methods, the ALD method can avoid calculating equivalent static wind loads （ESWLs）. Finally, a transmission tower structure is used as a numerical example to verify the feasibility and accuracy of the ALD method.
