卡特里娜飓风于 2005 年 8 月 29 日登陆，对建筑环境造成严重破坏，包括建筑物、道路和桥梁、电力和水的公用分配系统、废水收集设施以及重要的通信网络。本文详细介绍了 MCEER 组织的卡特里娜飓风过后立即对墨西哥湾沿岸进行的灾后实地勘察。勘察的目的是从多种灾害的角度检查和记录卡特里娜飓风的影响。更具体地说，正在评估从卡特里娜飓风中汲取的经验教训，以减轻未来飓风造成的损害，以及地震或恐怖袭击等其他极端事件造成的损害。例如，该任务的多灾种目标是确定地震后通常观察到的损害与卡特里娜飓风造成的损害之间的相似性，目的是确定可以减轻风和风暴潮力造成的结构损害的抗震设计原则。研究人员观察到，包层、窗户和屋顶安装设备的非结构性损坏造成了巨大损失，而结构框架却没有损坏。然而，在密西西比海岸等风暴潮地区，暴露在风暴潮和驳船等大型风暴潮碎片影响下的建筑物和桥梁出现了结构性损坏，其中大部分与海啸风险有关。
Hurricane Katrina made landfall on August 29, 2005 causing significant damage to the built environment including buildings, roads and bridges, utility distribution systems for electric power and water, waste water collection facilities, and vital communication networks. This paper details post-disaster field reconnaissance of the Gulf Coast immediately following Hurricane Katrina organized by MCEER. The objectives of the reconnaissance were to examine and document the impact of Hurricane Katrina from a multi-hazard perspective. More specifically, lessons learned from Hurricane Katrina are being evaluated to mitigate damage not only from future hurricanes, but also from other extreme events such as earthquakes or terrorist attacks. As an example, a multi-hazard objective of this mission was to identify similarities between damage typically observed after earthquakes and damage caused by Hurricane Katrina with the goal of identifying seismic design principles that could mitigate structural damage caused by wind and storm surge forces. Researchers observed extensive losses from nonstructural damage to cladding, windows, and roof-mounted equipment while the structural frame remained undamaged. In storm surge regions such as the Mississippi coast, however, structural damage was observed in buildings and bridges exposed to storm surge and impact from large storm surge debris such as barges, much of which relates to tsunami risk.
