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).

该奖项为加州大学伯克利分校(UCB)提供资金，以升级小乔治·E·布朗的实验能力。地震工程模拟网络(NEES)UCB的可重构反应墙地震模拟器设施，将由NEES Consortium，Inc.在2005财年至2014财年作为国家共享设施运营。UCB NEES现场的主要设备包括坚固的反应底板、可重新配置的反应墙、液压供应、七个长冲程高速执行器、128通道数据采集系统(DAQ)、一系列仪器和一台400万磅的压缩张力机，能够对各种结构部件进行测试。所要求的设备为UCB NEES现场提供了额外的设备，是根据有兴趣使用该设备的地震工程研究人员提供的意见选定的，其中包括：一个升级到数据采集系统的频道、一个高保真表面损伤可视化(Hi-Fi Viz)系统和一个可重新配置的地震测试测试平台(重复)。额外的数据通道使测量和测试更多种类的结构成为可能。Hi-Fi Viz系统为研究人员提供了获取、量化和查看发生在部分或整个标本表面的损伤的能力。该系统将包括2D-3D投影仪系统、激光扫描系统和高速摄像系统。重复钢结构框架为各种测试配置提供了可重复使用的平台，从而减少了为每个实验建立专用测试装置的需要。这种设备将通过NEES联合体公司，UCB NEES设施提供给地震工程研究界。该奖项由NSF NEES重大研究设备和设施建设(MREFC)项目资助，是国家减少地震灾害计划(NEHRP)的一部分。
