摘要
对合肥电视塔脉动风荷载的仿真及其结构风振响应进行了分析。首先建立了脉动风荷载的功率谱密度函数矩阵。采用频谱表示法 ,仿真得到了作用在合肥电视塔上的与塔高竖向相关的 19条脉动风荷载时程样本。在此基础上 。
The simulation of fluctuating wind load acting on Hefei TV Tower and the wind induced vibration response analysis are presented in this paper.The matrix of power spectral density function of fluctuating wind load is established first.With the spectral representation method,19 samples of fluctuating wind load are simulated considering the vertical co relation.Then, the wind induced vibration response of the tower is calculated.
