CAREER: Modeling and Simulation of Wind Loads for Wind Hazard Mitigation

该研究为在结构可靠性评估中应用自然灾害荷载的精确表示提供了新的进展。重点是对建筑构件上的高度相关的非高斯极端风荷载进行建模和模拟。建模工作将集中在概率内容、空间和时间一致性、大面积的积分效应、与建筑围护结构中的极端风力相关的瞬变和更高阶现象。稳健的仿真方法将采用这些模型，并为可靠性分析的应用提供一致的框架。这将通过对严重载荷的更现实的处理来增强可靠性方法对抗危险设计的影响。在地面附近全面测量飓风风速的同时努力将为推进这项研究提供必要的数据。教育的目标是培养准备好进行设计以对抗自然灾害的工程师，并为这一新兴领域的研究生工作提供媒介。

The research offers advancements in the accurate representation of natural hazard loads for application in structural reliability assessment. The focus is on the modeling and simulation of highly correlated non-Gaussian extreme wind loads on building components. Modeling efforts will focus on the probability content, spatial and temporal coherence, integral effects over large areas, transient, and higher-order phenomena associated with extreme wind forces in the building envelope. Robust simulation methods will adopt these models, and provide a consistent frame-work for applications in reliability analysis. This will enhance the impact of reliability methods on hazard resistant design through a more realistic treatment of severe loading. Concurrent efforts in full-scale hurricane wind measurement near ground level will provide necessary data to advance this research. The educational goals are to produce engineers prepared to design against natural hazards, and to provide a medium for graduate work in this emerging field.
