The magnitude 8.8 earthquake that occurred in Chile on February 27, 2010, presents a unique opportunity to study the response of the modern built environment to large ground motions. Through support under this RAPID award, the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) equipment site operated by the University California, Los Angeles (UCLA), will send personnel and state-of-the-art monitoring equipment to Chile in March to gather strong-motion aftershock data from buildings and other structures as part of the NSF-supported Earthquake Engineering Research Institute (EERI) post-earthquake reconnaissance team. The UCLA team will deploy two 24-channel digital monitoring systems at initial monitoring sites to be selected with the EERI team and collaborating Chilean researchers. With Chilean support, the UCLA team will then deploy the monitoring systems on multiple structures for an initial two-week period. One of the monitoring systems will remain on structures in Chile through March and April, and be operated by newly-trained Chilean university staff and students. Data and equipment will then be retrieved during a second trip by one of the UCLA NEES staff in early May. The primary objectives of this RAPID award are the following: (1) to gather timely important data on the response of damaged and undamaged structures to strong shaking during aftershocks, (2) to provide a structural monitoring resource for the EERI post-earthquake reconnaissance team and Chilean researchers, and (3) to demonstrate the use of NEES resources for post-earthquake studies. Results of the monitoring will be posted on a web site as they are completed and widely publicized so that interested researchers will have access to information about these activities. This award is co-funded by the NSF Office of International Science and Engineering (OISE).

2010年2月27日发生在智利的8.8级地震，为研究现代建筑环境对大地面运动的反应提供了一个独特的机会。通过RAPID合同的支持，由加州大学洛杉矶分校（UCLA）运营的小乔治·e·布朗地震工程模拟网络（NEES）设备站点将于3月向智利派遣人员和最先进的监测设备，作为nsf支持的地震工程研究所（EERI）震后侦察小组的一部分，从建筑物和其他结构中收集强震余震数据。加州大学洛杉矶分校的研究小组将在最初的监测点部署两个24通道数字监测系统，这些监测点将与EERI团队和合作的智利研究人员一起选择。在智利的支持下，加州大学洛杉矶分校的研究小组将在最初的两周内在多个建筑上部署监测系统。其中一个监测系统将在智利的建筑物上运行到3月和4月，并由新培训的智利大学工作人员和学生操作。数据和设备将在5月初加州大学洛杉矶分校NEES工作人员的第二次访问中检索。RAPID的主要目标是：(1)及时收集受损和未受损结构在余震期间对强烈震动的反应的重要数据，(2)为EERI地震后侦察小组和智利研究人员提供结构监测资源，(3)展示NEES资源在地震后研究中的应用。监测结果完成后将在一个网站上公布，并广为宣传，以便感兴趣的研究人员能够获得有关这些活动的资料。该奖项由美国国家科学基金会国际科学与工程办公室（OISE）共同资助。
