RAPID: Effects of the January 2010 Haitian Earthquake on Selected Electrical Equipment

该RAPID奖将研究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发挥关键作用，通常由内部部件组成，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被充分地约束和/或锚固，这可能由于单元的翻转和/或平移而导致显著的损坏。将调查位于太子港地区的这些关键电力设备的性能，这些设备在海地地震期间受到强烈的地面运动。 研究工作将开始，于2010年4月在太子港地区确定的多达10个地点实地调查受损和未受损的电力设备。将对内部和外部设备损坏状态进行编目。 数据收集和整理工作将包括：（1）绘制所访问设施的区域地图，以及在设施中发现的电力设备损坏类型;（2）将设备的位置联系起来（包括受损和未受损的）与现有的美国地质调查局Shakemap数据;以及（3）量化在现场访问期间观察到的损坏状态的类型、损坏对设备可操作性的影响，以及对于损坏到无法修复的设备，具体设备及相关系统的损失影响。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易腐电气设备损坏信息至关重要。所收集的数据和分析结果将对未来的地震损失评估研究和正在进行的计划（如由联邦应急管理局支持的ATC-58工作：为新建和现有建筑物开发下一代基于性能的抗震设计程序）有价值。 检查选定的设备故障的后果也将提供信息的工程师，城市规划师和社会科学家谁是关心的非结构性故障对灾难恢复工作的影响。 将编写一份报告，提供损害调查摘要、损害类型说明和数据整理工作摘要。项目调查人员将在2010年夏季或秋季举行的海地地震RAPID奖研讨会上介绍研究结果。

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.
