Innovative Solutions For Risk Management And Mitigation of Damage Produced by Windthrown Trees

每年被风吹倒的树木给建筑物、生命线和车辆造成数百万美元的损失。在飓风或龙卷风中，这种类型的碎片甚至可能造成伤害和死亡。这项工作将通过将树的载荷和对冲击波的响应研究结果与自然风场模型相结合来研究缓解程序。将研究树木和直接风损害的综合影响，以及树木移除导致更多暴露的结构与树木相关损害风险的影响。降低风险的技术，如根加固，树冠减少，并在新的和现有的城市和郊区发展的背景下研究抗风物种的选择。这项工作对每年遭受极端大风袭击的美国大部分地区的人口来说可能是实质性的。

Each year windthrown trees produce millions of dollars in damages to structures, lifelines, and vehicles. In hurricanes or tornadoes this type of debris may even cause injury and death. This work will investigate mitigation procedures by coupling the results from research on tree loading and response to blast waves with natural wind field model. The combined effect of tree and direct wind damage will be studied as well as the effects of tree removal resulting in more exposed structures versus the risk of tree- related damage. Risk reduction techniques such as root reinforcement, tree crown reduction, and selection of wind resistant species will be examined in the context of new and existing urban and suburban developments. The benefits from this work could be substantive to the population of a big portion of the United States subjected every year to extreme wind episodes.
