UCB NEES Equipment Site Upgrade

该奖项为加州大学伯克利分校（UCB）提供资金，以提升乔治E的实验能力。小布朗地震工程模拟网络（NEES）将由NEES联合体公司运营的UCB可重新配置反应墙地震模拟器设施，2005 - 2014财政年度作为国家共享使用设施。 UCB NEES现场的主要设备包括一个强大的反应地板，一个可重新配置的反应墙，液压供应，七个长行程高速执行器，一个128通道数据采集系统（DAQ），一系列仪器和一个400万磅的压缩-拉伸机，可以测试各种各样的结构部件。 所要求的设备为UCB NEES站点提供了额外的设备，是根据对使用该设备站点感兴趣的地震工程研究人员的输入选择的，包括：64通道升级到DAQ系统，高保真表面损伤可视化（Hi-Fi Viz）系统和可重新配置的地震测试平台（REPEAT）。 额外的数据通道使仪器和测试更广泛的结构成为可能。 Hi-Fi Viz系统为研究人员提供了获取、量化和查看部分或整个样本表面损伤的能力。 该系统将包括2D-3D投影仪系统、激光扫描仪系统和高速摄像机系统。 REPEAT钢结构框架为各种测试配置提供了一个可重复使用的平台，从而减少了为每个实验构建专用测试装置的需求。 该设备将通过NEES联盟公司提供给地震工程研究界，UCB NEES设施。 该奖项由NSF NEES主要研究设备和设施建设（MREFC）项目资助，是国家地震灾害减少计划（NEHRP）的一部分。

This award provides funding to the University of California, Berkeley (UCB), to upgrade the experimental capabilities of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) reconfigurable reaction wall earthquake simulator facility at UCB that will be operated by NEES Consortium, Inc., as a national shared use facility during FY 2005 - FY 2014. The major equipment at the UCB NEES site, which consists of a strong reaction floor, a reconfigurable reaction wall, hydraulic supply, seven long-stroke high-speed actuators, a 128-channel data acquisition system (DAQ), a portfolio of instrumentation, and a four-million pound compression-tension machine, enables testing of a wide variety of structural components. The requested equipment provides additional equipment for the UCB NEES site, was selected based on input from earthquake engineering researchers interested in using this equipment site, and includes: a 64-channel upgrade to the DAQ system, a high-fidelity surface damage visualization (Hi-Fi Viz) system, and a reconfigurable test platform for earthquake testing (REPEAT). The additional data channels make it possible to instrument and test a wider variety of structures. The Hi-Fi Viz system provides researchers the capability to acquire, quantify, and view damage occurring on the surface of a portion of or the entire specimen. This system will include a 2D-3D projector system, laser scanner system, and high-speed camera system. The REPEAT steel structure frame provides a reusable platform for various test configurations, thus reducing the need to build special-purpose test set-ups for each experiment. This equipment will be available to the earthquake engineering research community through the NEES Consortium, Inc., UCB NEES facility. This award is funded by the NSF NEES Major Research Equipment and Facilities Construction (MREFC) project and is a component of the National Earthquake Hazards Reduction Program (NEHRP).
