On Saturday, February 27, 2010 at 03:34 am local time (06:34:14 UTC), a Mw 8.8 earthquake struck the central south region of Chile, affecting an area with a population exceeding eight million people. This earthquake caused damage to buildings, highways, railroads, ports, airports, and other facilities due to ground shaking, liquefaction, and tsunami. Chile is a country that, in response to a history of frequent strong earthquakes, has developed and implemented building standards aimed at achieving earthquake safe construction. Many of the Chilean standards are adopted from standards in use in the United States. Although the majority of buildings performed well, an estimated 50 mid-rise concrete buildings sustained damage requiring extensive repair or demolition. By studying these buildings, U.S. engineers can improve modeling, analysis, and design methodology for U.S. buildings. The purpose of this RAPID is to travel to Chile to conduct a systematic effort to recover perishable data from a sample of heavily damaged or collapsed mid-rise concrete buildings, including building drawings and specifications, materials samples, and detailed damage documentation. The results will be archived and made available to academic researchers and practitioners for detailed study. This data gathering is urgent because several of these buildings will be demolished within the next several months.The intellectual merit of this field investigation lies in the development of rapid data collection techniques and preparation of data for online archiving using the Network for Earthquake Engineering Simulation (NEES) (http://www.nees.org) data archive or other data archiving opportunities. As a real-world laboratory, Chile can serve as a complement to the laboratories of NEES. By using selected field equipment of NEES laboratories, this project will test their applicability to post-earthquake data gathering.The broader impacts of the proposed program are extensive. The field investigation will gather fundamental data from full-scale structures subjected to strong, long-duration shaking, and the results will be available to other researchers and practitioners to conduct detailed studies on aspects such as modeling, simulation including collapse, soil-foundation-structure interaction, and design methodology. The project team will collaborate with Chilean academics, students, and practitioners, thereby enhancing international research collaborations including exchange of important data, potentially including the earthquake strong motion recordings. The results of the program will be disseminated in several ways, including: by sharing results using the NEES capabilities, by involving earthquake professionals, and by presenting results at professional meetings and in journal papers. The results will benefit society through the means noted above, most directly by providing data for studies helping define appropriate engineering design requirements for earthquake-resistant buildings in the United States. Graduate and undergraduate student experiences will be enhanced by active participation in the activity including collaboration with overseas researchers.This award is part of the National Earthquake Hazards Reduction Program (NEHRP).

2010年2月27日，星期六，当地时间凌晨3点34分（UTC时间6点34分14秒），智利中南部地区发生里氏8.8级地震，影响人口超过800万的地区。 这次地震由于地面震动、液化和海啸造成建筑物、公路、铁路、港口、机场和其他设施的损坏。智利是一个历史上经常发生强烈地震的国家，它制定并实施了旨在实现地震安全建筑的建筑标准。智利的许多标准是从美国使用的标准中采用的。虽然大多数建筑物状况良好，但估计有50座中层混凝土建筑物受到损坏，需要进行大规模维修或拆除。通过研究这些建筑，美国工程师可以改进美国建筑的建模、分析和设计方法。该RAPID的目的是前往智利进行系统的努力，从严重损坏或倒塌的中层混凝土建筑物的样本中恢复易腐烂的数据，包括建筑图纸和规格，材料样本和详细的损坏文件。结果将存档，供学术研究人员和从业人员详细研究。这种数据收集是紧迫的，因为这些建筑物中有几个将在未来几个月内被拆除。这种实地调查的智力价值在于开发快速数据收集技术和准备数据，以便使用地震工程模拟网络（NEES）（http：//www.example.com）数据存档或其他数据存档机会进行在线存档。www.nees.org作为一个现实世界的实验室，智利可以作为NEES实验室的补充。通过使用NEES实验室选定的现场设备，该项目将测试它们在地震后数据收集中的适用性。现场调查将从遭受强烈，长时间震动的全尺寸结构中收集基本数据，其结果将提供给其他研究人员和从业人员，以进行建模，包括倒塌，土壤-基础-结构相互作用和设计方法等方面的详细研究。该项目团队将与智利学者、学生和从业人员合作，从而加强国际研究合作，包括交换重要数据，可能包括地震强震记录。该计划的成果将通过几种方式传播，包括：通过使用NEES功能共享结果，通过让地震专业人员参与，以及通过在专业会议和期刊论文中展示结果。研究结果将通过上述方式造福社会，最直接的方式是为研究提供数据，帮助确定美国抗震建筑的适当工程设计要求。研究生和本科生的经验将通过积极参与活动，包括与海外研究人员的合作得到加强。该奖项是国家地震灾害减少计划（NEHRP）的一部分。
