摘要: 根据脉动风压功率谱与脉动风速功率谱之间的关系,利用风压功率谱密度函数矩阵的分解,通过一组余弦函数的和对过黄河渡槽随机形式的脉动风荷载进行了计算机模拟。Abstract: Based on the relationship between the wind pressure spectrum and the wind speed spectrum,the pulsating wind load in random of the aqueduct across the Yellow River was simulated with a series of cosine functions by the decomposition of cross-spectral density matrix.
