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.

该研究为结构可靠性评估中自然灾害荷载的准确表达提供了新的思路。重点是建筑构件上高度相关的非高斯极端风荷载的建模和仿真。建模工作将集中在概率内容，空间和时间的连贯性，在大面积的整体效应，瞬态和高阶现象与极端的风力在建筑围护结构。鲁棒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。同时进行的近地面飓风风速的全面测量将为推进这一研究提供必要的数据。教育目标是生产准备设计对抗自然灾害的工程师，并提供一个媒介，在这个新兴领域的研究生工作。
