SGER: Collection of Perishable Data on Woodframe Residential Structures in the Wake of Hurricane Katrina

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分在洛杉矶的普拉克明教区登陆。不幸的是，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和坚固的建筑物。本研究的目的是收集和处理路易斯安那州、亚拉巴马州、和密西西比，可用于研究和设计代码开发社区，以提高性能的木结构的强风（横向）负荷。一项提案要求提供资金，以支持由学术界和工业界成员组成的多机构灾后工作组在卡特里娜飓风后立即获取有关木结构破坏和性能的易腐数据。这样的数据是易逝的，一旦修理开始和清理木结构碎片正在进行中，它不再是可用于工程界，以便我们可以学习如何提高性能的木结构在非常大风。美国绝大多数的住宅建筑都是轻型结构或木结构建筑，包括路易斯安那州、亚拉巴马州和密西西比州的受灾地区。这次SGER赠款申请的资金将用于（1）9月中下旬结构木材和风力专家小组前往受灾地区，特别是（2）记录从飓风路径边缘和内陆到海岸的4天系统性工作对住宅木结构的破坏。不需要人员时间，只需要为大学小组成员提供最低限度的差旅费。所有参加该小组的行业人员都同意支付自己的费用。其中包括由APA副总裁汤姆威廉姆森和史蒂芬普赖尔，在辛普森强领带横向力抵抗系统经理组织的"APA-工程木材协会"团队。因此，拟议的努力是学术界、代码开发人员、专业工程师和工业界的合作。拟议的SGER项目的智力价值主要是使用实时GIS应用程序，将严重和中度风害与NOAA风速数据相关联，后者将有助于提高性能-基于风力工程的概念。拟议研究的更广泛影响包括传播可用于通过设计代码开发提高木结构性能的数据，从而减少居住在木结构房屋中的家庭的风险，并减少损害。

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.
