运用静态转换法模拟了弦支穹顶结构上层网壳节点的非高斯脉动风压,将风压加载至弦支穹顶进行时程分析,求出了弦支穹顶节点的位移响应时程以及根方差,并与高斯脉动风压的计算结果做对比分析。分析表明:非高斯风压作用下弦支穹顶结构的位移极值是高斯风压作用下的2.3倍;位移响应根方差比高斯风压作用下大20%~50%。 The static non-Gaussian pulsating wind pressure is simulated by the static transformation method and the wind pressure is applied to the chord support dome for time history analysis. The displacement response time history and root variance of the chord support node are obtained. And compared with Gaussian pulsating wind pressure calculation results. The analysis shows that the displacement of the suspend-dome structure under non-Gaussian wind pressure is 2.3 times that of Gaussian wind pressure and the root variance of displacement response is 20% -50% larger than that of Gaussian wind pressure.
