Numerical Simulation Study on the Characteristics of Typhoon Wind-Field in Xiamen Region

厦门地处东南沿海，是我国遭受台风灾害最为严重的地区之一。近年来，随着经济发展和城市化建设加速，高层建筑、大跨结构、高耸结构不断涌现，而这类结构对风荷载非常敏感，风荷载是结构抗风设计的主要设计参量。现行规范给定的基本风速、风压是根据气象部门实测风资料统计分析的，但在台风多发区，台风条件下测量仪器易损、测量时间间隔过长都可能造成风载估计不准确。利用台风模拟推算不同重现期的极值风速、风压是目前国外应用较为广泛的研究方法，能够为结构抗风设计提供更为准确的风载信息。 台风关键参数和台风风场是进行台风模拟的前提。台风关键参数是能够表示台风性征的物理量，本论文依据厦门地区1959~2008年台风资料，研究...Xiamen, located at China’s southeast coast, is one of the most typhoon-prone regions all over the world. With the rapid development of economy and society during the last few decades, super-high buildings, large-span and high-rise structures are emerging, which are very susceptible to wind loads. It is well known that wind is mainly governed load in the design process of these structures, so it is...学位：工学硕士院系专业：建筑与土木工程学院土木工程系_结构工程学号：2532007115219
