通过对梅州体育场进行测压试验,得到平均风压系数、脉动风压系数,对其风压特性做了详细分析。结果表明:控制体育场屋面的风压主要为负压,屋盖凸起处气流分离较大,导致其负压较大;当来流由低屋面进入高屋面时,在高屋面区域产生“上吸下顶”的受荷情况,负压增大;通过对屋盖测点风压时程第三、第四阶矩的统计分析发现,非高斯性测点主要分布在屋盖气流分离区和受尾流旋涡影响的区域;高斯分布和三参数伽马分布能较好地描述体育场表面风压概率特性;Sadek-Simiu法考虑了脉动风压非高斯特性,能准确地估计非高斯风压的极值。 Meizhou stadium through the pressure test, get the average wind pressure coefficient, fluctuating wind pressure coefficient, the wind pressure characteristics of a detailed analysis. The results show that the main wind pressure in the control roof of stadium is negative pressure, and the air flow in the convex part of the roof is separated greatly, resulting in a large negative pressure. When the flow from low roof to high roof, Suction under the top "load conditions, negative pressure increases; by measuring the roof pressure gauge third and fourth moments of statistical analysis found that non-Gaussian test points are mainly distributed in the roof airflow separation zone Gaussian distribution and three-parameter gamma distribution can well describe the probability of wind pressure on the stadium surface. The Sadek-Simiu method considers the non-Gaussian characteristics of fluctuating wind pressure and can accurately estimate the non-Gaussian wind pressure The extreme value
