| 摘 要： | 通过对某双塔高层建筑进行了风洞试验,对该双塔高层建筑表面风压的非高斯分布特性进行了研究;基于各风向角下风压系数的三阶、四阶矩统计量,对高层建筑各立面风压进行了高斯与非高斯分布的分区;最后,对高斯区和非高斯区设计风压系数的峰值因子取值问题进行了探讨,发现在实际应用中对非高斯区的峰值因子取值偏小。

| Abstract: | The non-Gaussian features of the wind-induced pressure on the twin-tower tall buildings are studied through the wind tunnel tests.Based on the third and the fourth order statistical moments of wind pressure coefficients,the Gaussian and non-Gaussian regions of the wind pressure at a given wind direction are identified on the surfaces of the twin-tower tall buildings,respectively.Finally,the determination method of peak factor for the design wind pressure coefficient at the Gaussian and non-Gaussian regions ... |
