摘　　要：本文对Davenport风速谱和Kaimal风速谱进行了分析比较,并且以江苏某通讯角钢塔为例,采用两种不同的风速谱计算了结构的风振响应,得出了在通讯角钢塔的工程计算中Kaimal风速谱更加接近实际风速时程的结论。A comparative study is performed between Davenport Wind Spectrum and Kaimal Wind Spectrum in the design of communication tower.A communication angle steel tower in Jiangsu Province is randomly chosen as a sample in the paper,and two different wind spectrums are used to calculate the wind-induced vibration of the structure.A conclusion is drawn that Kaimal wind speed spectrum can more accurately simulate the real wind speed time-history than davenport wind spectrum in the design of communication angle steel tower.
