摘要：

为了更好地确定建筑表面的设计极值风压,以具有“靴型”造型的复杂超高层建筑为例,研究非高斯峰值因子的计算方法.在风洞试验的基础上对各风向角下的风压系数时程数据进行三阶、四阶矩统计量分析,研究该复杂超高层建筑表面风压的非高斯分布特性.分别通过基于零穿越率的峰值因子法、改进峰值因子法、SadekSimiu法和改进Gumbel法对各风向角下风压数据的峰值因子进行估计,并在改进峰值因子法的基础上提出偏度非高斯峰值因子法.对各种方法的适用性及计算结果进行对比分析表明,改进峰值因子法在峰度小于3的情况下不适用；偏度非高斯峰值因子法与SadekSimiu法相比,两者的计算结果十分吻合.
Abstract:

Peak factors of non-Gaussian pressure process was investigated by taking a complex super-tall building with a boot-like shape for example in order to evaluate the design pressure coefficients on building surface more properly. The third and the fourth order statistical moments of wind pressure coefficients were analyzed based on the wind tunnel test. The non-Gaussian characteristics of wind-induced pressures on the complex building were systematically analyzed. The traditional peak factor method based on a zero-crossing rate, the improved peak factor method, the Sadek-Simiu method and the improved Gumbel method were employed to estimate the peak factors of wind-induced pressures. A new skewness-parameter non-Gaussian peak factor method was developed based on the improved peak factor method in order to overcome the shortcomings of the improved peak factor method. The applicability of various methods was discussed and compared to each other. Results show that the improved peak factor method is not applicable for some pressure processes with kurtosis smaller than three. Results of the proposed method accorded well with that of the Sadek-Simiu method.
