AbstractOne of the worst natural disasters in U.S. history is hurricane Katrina which madelandfall on August 29, 2005 at 7:10 a.m. in Plaquemines Parish, LA. Tragically, Katrinacaused widespread damage and loss of life in several states but has also provided anopportunity to collect data which may be useful for design engineers and building codeofficials in order to design safe and strong buildings in the future. The objective of theproposed study is to gather and process perishable data on residential woodframestructures in non-flooded regions of Louisiana, Alabama, and Mississippi that canbe used by the research and design code development community to improve theperformance of woodframe structures to strong wind (lateral) loading.This Small Grant for Exploratory Research (SGER) proposal is requesting funding tosupport the acquisition of perishable data on damage to and performance of woodframestructures immediately following hurricane Katrina by a multi-institutional post-disasterteam made up of members from academia and industry. Such data is perishable in thatonce repairs begin and clearing of woodframe debris is underway it is no longer availableto the engineering community in order that we may learn how to improve theperformance of woodframe structures during very high winds. The vast majority of theresidential building stock in the U.S. is light-frame, or woodframe, construction includingthe affected areas in Louisiana, Alabama, and Mississippi.The funds requested for this SGER grant will be used for (1) travel to and around theaffected area in mid to late September for the post-disaster team of structural wood andwind experts, and specifically to (2) record damage to residential woodframe structuresfor 4 days systematically working from the edge of the hurricane path and inland towardthe coast. A small amount of support costs is also requested for materials such as film,gasoline, etc. No personnel time is requested, and only minimal travel-relatedexpenses for the university team members are being requested. All industrypersonnel participating with the team have agreed to pay their own expenses. Theseinclude the "APA-The Engineered Wood Association" team organized by the APA VicePresident Tom Williamson and Steven Pryor, the lateral force resisting systems managerat Simpson Strong Tie. Thus the proposed effort is a collaboration of academics, codedevelopers, professional engineers, and industry.The intellectual merit of the proposed SGER project will be mainly the use of real-timeGIS applications, correlation of severe and moderate wind damage with NOAA windspeed data, the later of which will help with development of performance-based windengineering concepts.The broader impacts of the proposed research includes the dissemination of data thatcan be used to improve the performance of woodframe structures through design codedevelopment, thus decreasing risk to families living in woodframe houses, as well as reducing damage.

美国历史上最严重的自然灾害之一是卡特里娜飓风，它于2005年8月29日上午7点10分登陆。路易斯安那州普莱克明斯教区。可悲的是，卡特里娜飓风在几个州造成了广泛的破坏和生命损失，但也提供了一个收集数据的机会，这些数据可能对设计工程师和建筑规范官员有用，以便在未来设计安全而坚固的建筑。这项拟议研究的目的是收集和处理路易斯安那州、阿拉巴马州和密西西比州非洪灾地区住宅木架结构的易腐烂数据，研究和设计代码开发社区可以使用这些数据来改善木架结构在强风(横向)荷载下的性能。这项小额探索性研究拨款(SGER)提案要求提供资金，以支持由一个由学术界和工业界成员组成的多机构灾后小组立即获取关于木架结构损坏和性能的易腐数据。这样的数据很容易腐烂，因为一旦开始维修和清理木框碎片，工程界就不再可以获得这些数据，以便我们可以学习如何在大风中改善木框结构的性能。美国绝大多数住宅建筑是轻框架或木结构建筑，包括路易斯安那州、阿拉巴马州和密西西比州的受灾地区。为这项SGER拨款申请的资金将用于(1)由结构木材和风力专家组成的灾后团队在9月中下旬前往受灾地区及其周围，特别是(2)记录住宅木结构结构的损坏情况，从飓风路径边缘和内陆到海岸有系统地工作4天。还要求为胶片、汽油等材料支付少量支助费用，不要求人员时间，只要求为大学团队成员提供最低限度的差旅费用。所有随队参赛的行业人员已同意自付费用。其中包括由APA副总裁汤姆·威廉姆森和史蒂文·普赖尔组织的“APA-工程木材协会”团队，他们是Simpson Strong Tie的侧向力抵抗系统经理。因此，拟议的工作是学者、代码开发人员、专业工程师和业界的合作。拟议的SGER项目的智力优势将主要是使用实时地理信息系统应用程序，将严重和中度风灾与NOAA风速数据进行关联，后者将有助于开发基于性能的风工程概念。拟议研究的更广泛影响包括传播数据，这些数据可用于通过设计代码开发来改善木结构结构的性能，从而降低居住在木结构房屋中的家庭的风险，以及减少损害。
