联邦紧急管理局(fema)2021年初步灾害评估(pda)口袋指南说明书
PDA Pocket Guide August 2021This Page Intentionally Left BlankOverviewThe Preliminary Damage Assessment (PDA) Pocket Guide serves as a quick reference tool for FEMA, state, local, tribal, and territorial (SLTT) government partners conducting PDAs to determine the magnitude of damage and impact of disasters. For more detailed information on PDAs, refer to the FEMA Preliminary Damage Assessment Guide.What are Preliminary Damage Assessments?The PDA process is a mechanism used to determine the impact and magnitude of damage and the resulting unmet needs of individuals, businesses, the public sector, and the community. Information collected is used by the state as a basis for the governor's request and by FEMA to document the recommendation made to the President in response to the governor's request.With the support of the state, tribe, or territory, local governments first conduct initial damage assessments (IDA) to determine if they require federal support. Once SLTT governments determine their capability to respond to or recover from the event is exceeded, the state, tribe, or territory requests a joint PDA with FEMA.The PDA ProcessRemindersKey Information SLTT Can Provide FEMATo expedite and streamline the joint PDA process, SLTT governments should collect and document damage information, including the following:•Locations of damages (including projected damages) using Global Positioning System (GPS) or annotated maps;•Damage dimensions, materials, and the size or capacity of damaged facility elements;•Representative sample of photographs of damage;•Known access and functional needs (AFN) populations;•Location of displaced families;•How the state/tribe/locals are assisting (state disaster programs, food stamps, etc.);•Lack of temporary housing; and•Primary languages spoken.The list of federally recognized tribes can be found here for reference.Do’s and Don’ts of the PDA ProcessThis Page Intentionally Left BlankIndividual AssistanceFEMA individual assistance (IA) programs deliver supplemental assistance to disaster survivors for unmet needs caused by a disaster. Support may include assistance for temporary housing and housing repairs, critical disaster-related expenses, the replacement of essential personal property, and funding to the SLTT government for IA program services. For more information, refer to the Individual Assistance Program and Policy Guide (IAPPG).Degrees of Damage DefinitionsFor the purposes of efficiency, FEMA has established four categories of damage that an impacted home may fall within: destroyed, major, minor, or affected. In many cases, the size and needs of the unfolding disaster will not allow PDA teams to conduct a detailed review of each home. Joint PDA teams should use the following standards for categorizing degrees of damage:•Affected: a home is considered affected if thedamage to the home is mostly cosmetic.•Minor: a home with repairable non-structural damage.•Major: a home with structural damage or othersignificant damage that requires extensive repairs.•Destroyed: the home is a total loss.For more detailed information on the four degrees of damage, reference the degree of damage tables presented later in this pocket guide. I n d i v i d u a l A s s i s t a n c eEssential Living SpacesDuring the PDA process, it is important to consider what is considered an essential living space. An essential living space is a room within a home that serves the function of a bedroom, bathroom, kitchen, and/or living room that is regularly occupied or used by one or more members of the household and requires repair to bring its functionality back to the home (e.g., kitchens are considered essential as long as there is not another undamaged kitchen in the home).Inaccessible ResidencesFor both manufactured and conventionally built homes, inaccessible residences are those in which damage to the home cannot be visually verified because of disaster-related loss of access.•In the case of flooding incidents, flood waters are blocking access to residences by covering, washingout, or destroying roads, bridges, or access routes sothat the degree of damage cannot be visually verified.•In the case of non-flood incidents, debris from landslides, mudslides, severe soil erosion, orblowdown is blocking access to residences bydisrupting or destroying roads, bridges, or access routes so that the degree of damage cannot bevisually verified.

箱式建筑施工工艺流程
箱式建筑施工工艺流程The construction process of modular buildings, also known as box-like buildings, involves a series of stepsthat ensure the efficient and streamlined assembly of the structure. From design to completion, this construction technique offers numerous advantages over traditional methods. In this article, we will explore the various stages of the box-style building construction process, highlighting its benefits and addressing potential challenges.The first step in constructing a box-style building is the design phase. Architects and engineers collaborate to create a detailed plan that meets the client's requirements and complies with local building codes. This stage involves considering factors such as the building's purpose, size, layout, and aesthetic appeal. The use of computer-aided design (CAD) software allows for precise measurements and accurate visualizations, enabling stakeholders to make informed decisions.Once the design is finalized, the fabrication of modular components begins. These components, also known as modules or boxes, are prefabricated off-site in acontrolled factory environment. The controlled environment ensures high-quality construction and minimizes the risk of weather-related delays. The modules are typically constructed using steel or wood frames, which are then clad with various materials such as concrete, glass, or metal panels.After fabrication, the modules are transported to the construction site. This transportation phase requires careful planning and coordination, as oversized modules may require special permits or escorts. The modules are delivered using flatbed trucks or other specialized equipment and are carefully positioned using cranes or other lifting machinery. Once on-site, the modules are then secured together, forming the final structure.The assembly of the modules is a relatively quick and efficient process. The modules are designed to interlock,allowing for easy and precise alignment. This eliminates the need for extensive on-site construction work, such as pouring concrete or erecting walls. The use of modular components also allows for flexibility in the building's layout, as modules can be easily added, removed, or reconfigured to accommodate changing needs.One of the key advantages of box-style building construction is its time and cost efficiency. The off-site fabrication of modules reduces on-site construction time, resulting in faster project completion. Additionally, the controlled factory environment allows for better quality control and reduces the risk of errors or defects. The reduced construction time also translates to cost savings, as labor and equipment costs are minimized.Furthermore, box-style buildings are known for their sustainability. The modular construction process generates less waste compared to traditional construction methods, as materials can be recycled or reused. Additionally, the controlled factory environment allows for more efficient energy usage and reduces the environmental impact of theconstruction process. The ability to easily disassemble and relocate modules also promotes sustainability, as buildings can be repurposed or relocated rather than demolished.Despite its numerous benefits, box-style building construction does present some challenges. The transportation of oversized modules can be logistically complex, requiring careful planning and coordination. Additionally, the need for specialized equipment, such as cranes, can add to the overall project cost. Moreover, while modular construction offers flexibility in design, it may not be suitable for highly customized or intricate architectural designs.In conclusion, the construction process of box-style buildings involves several stages, from design to assembly. The use of modular components offers numerous advantages, including time and cost efficiency, sustainability, and flexibility. Despite some challenges, the popularity ofbox-style construction continues to grow, as it provides a practical and innovative solution for various building projects.。

不锈钢点焊结构车体FEA建模方法
不锈钢点焊结构车体FEA建模方法摘要:针对不锈钢车体点焊结构的“点传力”特性,提出了位移主-从约束关系建模思想,并通过数值试验验证了采用位移主-从约束关系来模拟焊核比现有其它的模拟方法具有更高的精度.以城市轻轨动车组不锈钢点焊车体为应用对象,基于位移主-从约束关系建立了该车车体的有限元模型,计算结果与试验测试结果基本一致,证明了模型的正确性,为今后该类车型的设计与开发打下了良好的技术基础.关键词:FEA,位移耦合,点焊结构点焊是地铁车辆、城市轻轨车辆、甚至高速动车组的不锈钢车体结构大量金属板构件间的主要连接形式,分布于车身各部位,数量达上万个.点焊结构主要特点是:结构紧凑、重量轻、强度高、耐腐蚀.同时,它的制造工艺比较复杂,技术要求高,因此,尽管点焊结构车辆在国外已经获得了广泛应用,在国内则刚刚开始研制[1-2].如何把握点焊结构的力学特性,建立高精度的车体FEA计算模型已成为不锈钢点焊车研制过程中计算人员极为关注的问题.当前点焊结构常采用实体单元、梁单元、刚性单元和主-从关系(即位移耦合)来模拟焊核[3-4].从理论上说,点焊结构用适当高度的块体元模拟时,则可获得较高的精度,但对于大量均布、密集排列的焊点的不锈钢车体结构来说这将导致单元/结点数量急剧增加而不可行,因此,必须抓住不锈钢点焊车传力的主要特征创建FEA模型.与车辆结构尺寸相比,点焊焊核自身的尺寸可以忽略不计,在有限元模型中,可以将它们视为仅是整体坐标系下的一个“点”,在外载荷作用下,结构依靠这些“点”传递内力,这类结构可称为“点传力结构”.基于位移主-从控制关系原理[5],本文认为对于不锈钢点焊车体这类典型的“点传力结构”,用位移的主-从约束关系来模拟焊核(即等价于在计算模型中被焊接连接的两点之间位移完全一致)是更为合理的,并通过数值试验证明了主-从约束关系比其它建模方法具有更高的精度.基于位移主-从约束关系建立了城市轻轨动车组不锈钢点焊车体的FEA模型,根据相关标准进行加载计算,通过与物理试验的比较,验证了计算模型的合理性和有效性.1 主-从控制关系的正则方程主-从关系(位移耦合),指的是当一个结点被定义为另一个结点的从结点后,该从结点就失去了位移的独立性,它的位移只能且必须从属于主结点.主结点上的位移处理为独立位移,从结点上的位移为相关位移.在应用最小总势能原理求基于位移法的结构正则方程时,相关位移对总势能的贡献是通过与之有关的独立位移和指定位移表达的.结构的总势能为2 各种方法对比分析本文提出用位移主—从约束关系描写不锈钢点焊车体的点焊传力,这意味着模型中的每一点焊的焊核均被凝聚成一点,那么,这种简化与其它建模方法相比精度到底多高?以下用实体单元、梁单元、刚性单元和主-从关系(即位移耦合)为点焊结构建模来讨论各种方法的精确性.假设薄板A与B用点焊方式焊接,其厚度分别为t1与t2,t1薄板右端均匀作用有F吨拉力,t2薄板左端被约束住.焊核为三维椭球,其最大剖面的直径为d.在各方法的计算模型中,板的中心为焊点位置,也为坐标原点,梁单元的物理属性取决于板材,单元直径为d,单元长度为(t1+t2)/2;刚性单元,无物理属性,单元长度为(t1+t2)/2;实体单元物理属性取决于板材,单元尺寸取决于t1,t2;位移主-从约束不需要定义材料属性,只需指定六个自由度之间位移主-从约束关系.以实体元计算结果为标准,t1薄板上载荷方向的应力误差比列入附表.表中方法1为采用梁单元;方法2为采用刚性单元;方法3为采用位移耦合.表中位置点1至点8依次为t1薄板上过原点与载荷方向一致的坐标轴上等距离的点;位置点9至点16依次为t1薄板上过原点与载荷方向垂直的坐标轴上等距离的点.表中应力误差比的定义为(σ-σ0)/σ0,其中σ0为实体元计算结果.由附表可以看出:位移主—从约束建模方法的误差较小,刚性单元和梁元的较大.实体单元和位移耦合的两个模型沿外载荷方向的应力值比较如图1所示.结果表明:两种模型高应力区域一致;焊核附近,位移耦合模型的应力值要大于实体单元模型的,稍离开焊核,两种模型应力值几乎相同.3 工程验证城市轻轨动车组不锈钢点焊车体是典型的点传力结构,全部采用高强度车辆专用的冷弯或轧压工艺制造的不锈钢型材.除车顶、地板的波纹板之间的连接采用缝焊,其余板与梁、柱及部件与部件之间的连接均采用接触点焊.由于板薄,板与板、板与梁(柱)和柱与柱之间只能采用搭接接头,除2层、3层搭接外,最多还有5层板搭接.该不锈钢车体大约有4万个焊点,该车典型的焊接示意图如图2所示.不锈钢点焊车体在承受外载后,载荷通过数万焊点将力传递到车体各部,并由此产生车体各处的变形与应力,这一特点,在建模时必须真实体现,否则,计算模型将会失真,并将导致计算结果失真.假定车体构件的每一“点对”之间,一旦形成点焊,尽管这一点焊事实上占有一很小的面积,但相对车体构件尺寸而言,有理由视这两点被“焊成一点”,因此,在变形的过程中,点焊可以用位移主—从关系来描述.城市轻轨动车组不锈钢点焊车体有限元建模的关键问题是每一个焊点位置处必须要有结点生成.因此,在I-DEAS 软件(10.0)中创建真实地反映不锈钢车体构件之间的相互关系的、用于划分有限元网格的三维几何时,根据点焊位置,要一一创建“锚点”[6],因为“锚点”一经生成,在随后的单元网格生成过程中,“锚点”将自动转化为单元的结点,这样就为点焊的“点对”准确位置的确定创造了条件.不锈钢点焊车体四分之一的局部放大网格如图3所示.四分之一模型的求解规模为:单元总数132309;节点总数134659;焊点数8824.依据文献[7]进行加载计算,垂直总静载荷工况作用下车体和部件的Von.Mises应力云图如图4所示.该车FEA计算结果与强度试验测试结果[8]的对比如图5所示,由图5可以看出两者基本一致,因此,该计算模型质量很高.事实上,正是由于该性能仿真模型的高可靠性,设计人员才有可能进行一次又一次的方案对比.而相对最优方案也正是在这种一次又一次对比中逐步形成的,其重要意义不言而喻.5 结语FEA的置信度关键在于计算模型的质量,而创建一个计算模型的必备条件是计算机、仿真软件和使用者.事实上,功能再好的仿真软件,速度再快的计算机,也只能辅助建模者提高建模的效率而不提供建模的原则与技巧,计算模型的质量主要还是取决于使用者的理论素养和建模经验.只有具有良好的理论素养和厚实的建模经验才能够很好地消化吸收仿真软件中的精髓,并将其融化在仿真模型的建立过程之中,使仿真模型合理和科学.本文基于位移主-从约束关系(位移耦合)原理模拟不锈钢点焊车体的点焊,并利用I-DEAS仿真软件高级建模功能,建立了城市轻轨动车组不锈钢点焊车体的FEA模型.通过FEA 计算结果与物理试验结果的对比,证明本文的建模思想方法是切实可行的. 参考文献:[1]内田,博行.日本不锈钢车辆技术,国外铁道车辆[J],2001,38(4):1-4.[2]孙双进.开发生产不锈钢客车提高我国客车制造水平[J].铁道车辆,1998,36(6):18-21.[3]周长路,范子杰,陈宗渝,等,微型客车白车身模态分析[J].汽车工程,2004,26(1):78-80.[4]王宏雁,徐少英.有限元法在客车车身结构模态分析中的应用[J].北京汽车,2002,(1):13-15.[5]钟万勰.计算结构力学微机程序设计[M].北京:水利电力出版社,1984.[6]I-DEASMasterSeriesTMStudentGuide[M].StructuralDyn amicsResearchCorporation,1998.[7]JISE7105-1989.铁道车辆车体结构强度试验方法()[S].日本标准协会,1989.[8]天津滨海快速轨道交通不锈钢车体静强度试验报告[R].青岛:中国北车集团四方车辆研究所,2003.。
