以武汉市某雷达塔架为例，采用有限元方法对其进行时程风荷载作用下的动力时程分析，得到塔架的时程位移、时程速度和时程加速度响应，并将塔架结构在静力风荷载下的位移响应和最大应力与在脉动风荷载作用下的时程位移峰值和应力峰值作了对比和误差分析，为该类型的结构风振分析提供参考。%Taking some radar tower in Wuhan as the example,finite element method is carried out for the dynamic time-history analysis under wind load. The displacement and the responses of time-history velocity and acceleration can be achieved simultaneously. The displacement re-sponse and maximum stress of tower structure under static wind loads are compared with time-history displacement and stress peak under fluctua-ting wind load and error analysis is given,this type of structure wind vibration analysis to provide the reference.
