摘要
脉动风荷载数值模拟是进行风荷载响应分析的基础。采用三角级数法对脉动风荷载进行了模拟,并借助有限元分析软件,对风荷载作用下塔架结构的动力时程响应及频谱特征进行了分析。
Numerical simulation of turbulent wind load is the basis of the analysis for wind load response. In this paper, by using the trigonometric series method the history curve of turbulent wind load is simulated, and response and frequency characteristics is analyzed.
