| 摘 要： | 对幕墙结构中风荷载的脉动特性进行了分析，采用沿高度变化的E．Simiu风速谱，用改进的谐波叠加法模拟了不同高度处脉动风速和风压的时程曲线，给出了风荷载的计算公式，结果表明该方法简单有效，且能够反映脉动风的随机特性，解决了玻璃幕墙风荷载的动力计算问题。

| Abstract: | The pulsation characteristic of wind load acting on the curtain walls is analyzed. Based on the E.Simiu wind velocity power spectrum varying along the altitude of the engineering structure, the time history curves of pulsation wind velocity and pressure in different heights are simulated by improved superposition of harmonic method. The formula for calculating the wind load is proposed. The results show that this method is rational and available. The achievements in this paper may be referenced for the dynamic analysis of wind load for glass curtain walls. |
