摘要

摘要: 基于1959年~2008年厦门地区的台风详细资料,采用Yan Meng风场模型进行台风数值模拟,得到了台风极值风速序列,并推算出厦门地区不同重现期的极值风速,与年极值风速实测资料统计结果及现行规范值进行比较,为结构抗风设计提供了更为合理的荷载信息；同时,讨论了风向对极值风速分布的影响,为正确选择建筑方位提供理论指导。最后,基于Yan Meng风场不同半径位置处风剖面的变化规律,提取厦门地区沿高度的极值风速,研究了台风条件下的风剖面规律。

Abstract: Based on observed data of typhoons in Xiamen region during 1959- 2008, numerical simulation of typhoon is conducted using the Yan Meng wind-field model to obtain the extreme wind velocity series. Then, extreme wind velocity for different return periods is estimated and compared with the statistical results of the observed data of annual extreme wind velocity in Xiamen region, as well as the current structural code, to provide more accurate wind load information for the wind-resistant structural design. Furthermore, the effect of wind direction on extreme wind velocity is discussed in this paper to provide theoretical guidance of choosing appropriate building direction. Finally, gradient wind level as well as typhoon-governed wind profile in Xiamen region is proposed based on numerical simulation of the Yan Meng typhoon wind-field model.
