Damage Survey from Hurricane KatrinaABSTRACTHurricane Katrina wreaked massive damage along the Gulf Coast of Alabama, Mississippi and Louisiana. While much of the damage associated with hurricanes is related to wind and flooding, damage as a result of storm surge in coastal areas in particular can be significant, and this damage mechanism is very similar to what can happen during a tsunami. This is clearly the case for Katrina.Development of design guidelines for coastal construction to resist storm surge and tsunami wave loading has been hampered by the lack of experimental research and field data. Although excellent records are often collected of coastal run-up, either via field surveys or satellite imagery, the effects of storm surge and tsunami loading on the built infrastructure is often not well documented. To supplement our work under a recently-received NEES-R grant to develop Performance Based Tsunami Engineering (PBTE), we will survey the structural damage associated principally with storm surge and the resulting hydrodynamic forces on areas of the U.S. Gulf Coast.A significant amount of the damage to the Biloxi coast area appears to have resulted from the storm surge and waves. However, it appears that large engineered buildings withstood the storm surge and waves. Damage to these types of buildings appears to be primarily from debris, either water-borne or wind-borne. The former appears to have caused the most significant structural damage, including partial collapse of several large structures.A first hand assessment of the storm surge and debris impact damage from Katrina will help us to focus more clearly on the damage mechanisms that occur in both hurricane storm surge and tsunami conditions. We also anticipate that damage from unexpected sources will become evident. The survey represents a rare opportunity to document the damage in an industrialized country resulting from a tsunami-like event.

卡特里娜飓风造成的损失调查摘要卡特里娜飓风对阿拉巴马州、密西西比州和路易斯安那州墨西哥湾沿岸造成了巨大破坏。虽然与飓风相关的大部分损害与风和洪水有关，但沿海地区风暴潮造成的损害尤其严重，而且这种损害机制与海啸期间可能发生的情况非常相似。 卡特里娜飓风的情况显然就是如此。由于缺乏实验研究和现场数据，制定沿海建筑抵御风暴潮和海啸波浪载荷的设计指南受到了阻碍。 尽管通过实地调查或卫星图像通常可以收集到沿海上涨的优秀记录，但风暴潮和海啸载荷对已建基础设施的影响往往没有得到很好的记录。 为了补充我们最近收到的 NEES-R 拨款开发基于性能的海啸工程 (PBTE) 的工作，我们将调查主要与风暴潮相关的结构损坏以及由此产生的美国墨西哥湾沿岸地区的水动力。比洛克西海岸地区的大部分损坏似乎是由风暴潮和波浪造成的。 然而，大型工程建筑似乎经受住了风暴潮和海浪的考验。这类建筑物的损坏似乎主要是由水传播或风传播的碎片造成的。前者似乎造成了最严重的结构性损坏，包括几个大型结构的部分倒塌。对卡特里娜飓风造成的风暴潮和碎片冲击损害的第一手评估将帮助我们更清楚地关注飓风风暴潮和海啸条件下发生的损害机制。我们还预计，意外来源造成的损害将会变得明显。这项调查是记录工业化国家因海啸类事件造成的损失的难得机会。
