Upgrading, Development and Integration of Next Generation Earthquake Engineering Experimental Capability at Rensselaer's 100 g-ton Geotechnical Centrifuge

CMS-0086555 Dobry地震工程模拟网络（NEES）计划是NSF主要研究设备计划资助的一个项目。 根据NEES计划，该合作协议在伦斯勒理工学院（RPI）建立了一个NEES离心机地震工程研究设备站点。 RPI将设计、购买、建造、安装、调试和操作新设备，并对其现有的100 g吨岩土工程设备进行升级。升级后的地震监测站将于2004年或更早投入使用，并将作为国家共享的NEES设备站进行管理，具有远程观测和远程操作能力，以在2014年之前提供新的地震工程研究测试能力。 该NEES设备站点将通过高性能网络连接到NEES协作实验室。 共享使用的访问和培训将通过NEES联盟进行协调。 该奖项是同行评审的结果，该提案提交给项目招标NSF 00-6，NEES：地震工程研究设备。自1991年以来，RPI的岩土工程师已经成功地被RPI的教师和学生以及其他研究人员使用。 该图书馆位于RPI校园Jonsson工程中心的中心。 该奖项提供以下设备：（a）一个2D飞行振动台（两个原型水平部件）和相关联的2D层状箱容器，以允许更逼真的2D建模，（B）对振动器的修改，以使2D振动器能够安全操作，（c）一个四自由度机器人、机器人工具和相关联的软件，能够在飞行中执行诸如建筑和挖掘、打桩、地面修复、锥贯入以及静态和循环载荷测试的操作而不停止飞行器，（d）具有因特网远程观测/远程操作能力的联网数据采集系统，（e）两台高速摄像机、图像处理软件和商用传感器;（f）用于更好地解析测量模型响应的高级传感器;（g）附加仪器、特殊容器和其他设备。 该升级版将提供研究地震工程中三个重要问题的能力：由于土壤液化引起的横向扩展和流动破坏，由于液化和横向扩展引起的土壤-结构相互作用和基础响应，以及创新的边坡稳定系统的地震行为。该奖项包括一个分奖给圣地亚哥的加州大学，在发展的卫星的远程观测/远程操作能力的试点项目。 RPI将把升级后的实验室整合到其研究计划和本科生和研究生课程中，并为外部研究人员提供培训机会。

CMS-0086555DobryThe Network for Earthquake Engineering Simulation (NEES) Program is a project funded under the NSF Major Research Equipment Program. This cooperative agreement, under the NEES Program, establishes a NEES centrifuge earthquake engineering research equipment site at Rensselaer Polytechnic Institute (RPI). RPI will design, purchase, construct, install, commission, and operate new equipment for, and upgrades to, its existing 100 g-ton Geotechnical Centrifuge. The upgraded Centrifuge will be operational by 2004 or earlier and will be managed as a national shared-use NEES equipment site, with teleobservation and teleoperation capabilities, to provide new earthquake engineering research testing capabilities through 2014. This NEES equipment site will be connected to the NEES collaboratory through a high performance network. Shared-use access and training will be coordinated through the NEES Consortium. This award is the outcome of peer review of this proposal submitted to program solicitation NSF 00-6, NEES: Earthquake Engineering Research Equipment. RPI's Geotechnical Centrifuge has been successfully used by RPI faculty and students and other researchers since 1991. The Centrifuge is located centrally on the RPI campus in the Jonsson Engineering Center. This award provides the following equipment: (a) one 2D in flight shaker (two prototype horizontal components) and associated 2D laminar box container to allow for more realistic 2D modeling, (b) modifications to the Centrifuge to enable safe operation of the 2D shaker, (c) one four degree-of-freedom robot, robot tools, and associated software, capable of performing in flight operations such as construction and excavation, pile driving, ground remediation, cone penetration, and static and cyclic loading tests without stopping the Centrifuge, (d) a networked data acquisition system with Internet teleobservation/teleoperation capability, to be linked to the high-speed RPI Gigabit Ethernet Backbone, (e) two high-speed cameras, image processing software, and commercial sensors, (f) advanced sensors for better resolution of the measured model response, and (g) additional instruments, special containers, and other equipment. This upgraded Centrifuge will provide capabilities to investigate three important problems in earthquake engineering: lateral spreading and flow failure due to soil liquefaction, soil-structure interaction and foundation response due to liquefaction and lateral spreading, and the seismic behavior of innovative slope stabilization systems. This award includes a subaward to the University of California, San Diego, for a pilot project during the development of the Centrifuge's teleobservation/teleoperation capability. RPI will integrate experimentation with the upgraded Centrifuge into its research program and undergraduate and graduate curricula and provide training opportunities for outside researchers.
