This RAPID award will study the effects of the magnitude 7.0 January 12, 2010, Haitian earthquake on electrical equipment. Electrical equipment, such as switchgear, motor control centers, and small transformers, are vulnerable to damage from seismic ground motion if not properly designed, constructed, and installed. This equipment, which typically plays a critical role in post-earthquake response and recovery, is often comprised of internal components that may be damaged when subjected to strong accelerations. In addition, the electrical units as a whole are often not adequately restrained and/or anchored, which can lead to significant damage due to overturning and/or translation of the units. Performance of such critical electrical equipment, located in the Port-au-Prince region, which were subjected to strong ground motion during the Haitian earthquake will be investigated. The research effort will begin with field surveys during April 2010 of both damaged and undamaged electrical equipment at up to ten sites that have been identified in the Port-au-Prince region. Both internal and external equipment damage states will be cataloged. Data collection and reduction efforts will include: (1) regional mapping of the facilities visited and the types of electrical equipment damage found at the facilities; (2) correlating the location of the equipment (both damaged and undamaged) with the available U.S. Geological Survey Shakemap data; and (3) quantifying the types of damage states observed during the site visit, the impact of the damage to operability of the equipment, and for equipment damaged beyond repair, the impact of the loss of the specific equipment and related systems. It is critical to gather, catalog, and disseminate highly perishable electrical equipment damage information that can be used by researchers, practitioners, and equipment manufacturers. The gathered data and resulting analysis will be valuable to future earthquake loss estimation studies and to ongoing initiatives such as the ATC-58 effort supported by the Federal Emergency Management Agency: Development of Next-Generation Performance-Based Seismic Design Procedures for New and Existing Buildings. Examining the consequences of failure of selected equipment will also provide information to engineers, urban planners, and social scientists who are concerned with the impact of nonstructural failures on disaster recovery efforts. A report will be produced providing a summary of the damage survey, a description of the damage types, and a summary of the data reduction efforts. Project investigators will present results of the study at a workshop for Haitian earthquake RAPID awards in summer or fall of 2010.

RAPID项目将研究2010年1月12日海地7.0级地震对电气设备的影响。电气设备，如开关设备、电机控制中心和小型变压器，如果设计、建造和安装不当，很容易受到地震地面运动的损坏。这种设备通常在地震后的反应和恢复中起着至关重要的作用，通常由内部组件组成，当受到强烈的加速度时可能会损坏。此外，电气单元作为一个整体通常没有充分的约束和/或锚定，这可能导致严重的损坏，由于推翻和/或平移的单位。将对位于太子港地区的这些在海地地震期间受到强烈地面运动影响的关键电气设备的性能进行调查。研究工作将于2010年4月开始，在太子港地区已确定的多达10个地点对受损和未受损的电气设备进行实地调查。将对内部和外部设备的损坏状态进行分类。数据收集和减少工作将包括：(1)所访问设施的区域地图和在设施中发现的电气设备损坏类型；(2)将设备（损坏和未损坏）的位置与美国地质调查局的地震地图数据相关联；(3)量化现场考察中观察到的损坏状态类型，损坏对设备可操作性的影响，以及对于无法修复的设备，具体设备和相关系统损失的影响。收集、编目和传播研究人员、从业人员和设备制造商可以使用的高度易腐电气设备损坏信息至关重要。收集的数据和结果分析将对未来的地震损失估计研究和正在进行的倡议有价值，例如联邦紧急事务管理局支持的ATC-58努力：为新建筑和现有建筑开发下一代基于性能的地震设计程序。检查所选设备故障的后果也将为工程师、城市规划者和社会科学家提供信息，他们关注非结构性故障对灾难恢复工作的影响。将编制一份报告，提供损害调查的摘要、损害类型的描述和减少数据工作的摘要。项目调查人员将在2010年夏季或秋季海地地震RAPID奖的研讨会上展示研究结果。
