摘　　要：顺风向风振是随机振动 ,而索在其上作用风力时是非线性 ,因而带索的高耸结构风振是非线性结构的随机振动。本文在评述非线性结构的随机振动分析方法的基础上 ,提出较合理的分析方法和索上风力团聚在两端的线性化的实用方法。例子计算表明 ,提出方法简便又合理 ,可供应用参考。In the case of any cable subjected to wind loading directly,along wind vibration of tower structure with cables is random and nonlinear.In this paper,after the review of analysis method for random and nonlinear vibration,both a more reasonable analysis method and a practice method based on lumped wind loading on cable to both ends of it are presented.Examples show that these methods are convenient in calculation and more reasonable in theory,and may be a reference for application.
