| 摘 要： | 对结构高度为492 m的上海环球金融中心大楼顶部实测到的良态强风时段下的平均风速和脉动风速数据进行了分析,得到了3 s、10 min以及1 h时距下的平均风速值,并对其进行线性拟合.结果表明,10 min平均风速与3 s平均最大(瞬时最大)风速的比值约为0.876 8.根据实测数据,还分析了湍流度和阵风因子,结果表明,湍流度和阵风因子均随平均风速的增大而减小,此外,对比了部分时段内的实测脉动风速功率谱密度与VonKarman谱,两者较为吻合.

| Abstract: | The mean and fluctuating wind speed data of strong wind of normal climate measured on the top of Shanghai World Financial Center with a height of 492 m were analyzed.Mean wind speeds in different intervals of 3 s,10 min and 1 hour were separately computed.The results showed that the averaged mean wind speed ratio between 10 min mean wind speed and 3 s maximum mean wind speed was approximately 0.876 8.The formulas for the ratios were then derived by using curve-fitting technique.The turbulence intensity,gust... |
