摘要 首先总结了各国荷载规范中风荷载规定的差异,然后对某地26年的实测风速资料进行统计分析,分十六个风向处理数据,采用Gumbel极值分布模型基于不同样本进行极值风速预测,参照我国现行风荷载规范对计算结果进行分析;得到了分方向的极值风速计算结果,与现行规范的结果对比,说明分方向预测极值风速可以合理降低设防风速,使得工程设计更加经济合理。 Main differences in wind load standards of different countries are summarized firstly.Then a statistical analysis was made for the practical measured wind data of 26 years somewhere and the data were processed under sixteen wind directions.Extreme wind velocity was predicted using Gumbel extreme value distribution models based on different samples.The calculated results were analyzed according to the current wind load standards in china,and the extreme wind velocity was obtained for different directions.Upon the comparison with the results from the current code,the proposed solution can reduce the defence wind velocity reasonably,and make the practical design more economic and reasonable.
