9802629 Ham This award supports a 24 month Japan Society for the Promotion of Science (JSPS) Postdoctoral Fellowship for Dr. Hee J. Ham at the Institute of Industrial Science, Tokyo University in Japan. Dr. Ham will work with Dr. Shuzo Murakami of the Institute of Industrial Science on a research project entitled, "Numerical Simulation and Novel Tool Analysis of Dynamic Wind-Structure Interactions for Low- Rise Structures." The proposed research will involve applying computational fluid dynamics to simulate dynamic and unsteady wind flow and low-rise structure interactions. The results will be compared with physical wind-tunnel simulation data. Novel tools (proper orthogonal decomposition and continuous/discrete wavelet analysis) will be developed and applied to both data sets simulated by physical and numerical methods to characterize the dynamic wind flow and load patterns. The results of this cooperative research will improve the development of methods for mitigating the effects of dynamic surface pressure fluctuations on low-rise structures due to extreme wind. ***

9802629 Ham 该奖项为日本东京大学工业科学研究所的 Hee J. Ham 博士提供为期 24 个月的日本学术振兴会 (JSPS) 博士后奖学金。 Ham 博士将与工业科学研究所的 Shuzo Murakami 博士合作开展一项名为“低层结构动态风-结构相互作用的数值模拟和新型工具分析”的研究项目。 拟议的研究将涉及应用计算流体动力学来模拟动态和不稳定的风流以及低层结构的相互作用。 结果将与物理风洞模拟数据进行比较。 将开发新工具（适当的正交分解和连续/离散小波分析）并将其应用于通过物理和数值方法模拟的数据集，以表征动态风流和荷载模式。 这项合作研究的结果将促进减轻极端风造成的动态表面压力波动对低层结构影响的方法的开发。 ***
