The George E. Brown, Jr. 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 large-scale laboratory experimentation equipment site towards real-time hybrid seismic testing at the University at Buffalo, The State University of New York, Buffalo, NY. The University at Buffalo will design, construct, install, commission, and operate a modular and highly flexible dynamic testing facility for large-scale geotechnical and structural earthquake engineering experimentation. This equipment will be operation by September 30, 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 for large structural systems through 2014. This NEES equipment site will be connected to the NEES collaboratory through the University's vBNS connection, with Gigabit Ethernet capabilities. Shared-use access and training with be coordinated through the NEES Consortium. This award is an outcome of the peer review of proposals submitted to program solicitation NSF 00-6, "NEES: Earthquake Engineering Research Equipment." The following equipment is provided under this award: (1) Three 100 ton dynamic actuators equipped with dual 400 gpm servovalves, +/- 500 mm stroke, (2) two 200 ton static actuators with 15 gpm servovalves, +/- 500 mm stroke, (3) hydraulic distribution lines and manifolds, (4) surge tank and accumulators, (5) two hydraulic pumps of 185 gpm each for continuous operation which along with the accumulator banks can provide maximum flow of 1600 gpm for 30 seconds, (6) digital control system, (7) test control package for both static and dynamic tests, (8) upgrade and expansion of existing data acquisition system to accommodate teleobservation, teleoperation, teletransmission, and telestorage, (9) data management and processing system to accommodate real-time systems, data acquisition, storage, distribution and analysis, and test instrumentation, (10) equipment for teleobservation and teleoperation capabilities so that experiments on the equipment will be observable and controllable via high performance network connections, (11) video imaging equipment with the eventual goal of streaming real-time video, and (12) sensors and measurement devices. The experimental facility allows for multiple configurations of full-scale component tests combined simultaneously with real-time numerical simulations to investigate the seismic behavior of large structural systems incorporating use of actuators, reactions walls, strong floor, and shake tables (one moveable). Further, the equipment will be used to develop new hybrid testing algorithms for near full-scale/large-scale testing. The University has committed $4 million for expansion and infrastructure improvements of the Structural Engineering and Earthquake Simulation Laboratory in Ketter Hall on the University at Buffalo campus to house the upgraded and new equipment. This expansion includes a new research laboratory area with a strong floor and reaction walls, control rooms and offices for training and data processing, service areas, storage and office spaces, and a new 40 metric ton crane. The University at Buffalo will integrate this large-scale, high performance testing equipment into its research program and undergraduate and graduate curricula, provide training opportunities for outside researchers through on site courses, host visiting scholars, and develop a web-based teleoperation simulator of the NEES equipment.

乔治E.小布朗地震工程模拟网络（NEES）计划是美国国家科学基金会主要研究设备计划资助的一个项目。 根据NEES计划，该合作协议在纽约州立大学布法罗的布法罗大学建立了一个NEES大型实验室实验设备现场，用于实时混合地震测试。 布法罗大学将设计、建造、安装、调试和运营一个模块化和高度灵活的动态测试设施，用于大规模岩土和结构地震工程实验。 该设备将于2004年9月30日或更早投入使用，并将作为国家共享的NEES设备站点进行管理，具有远程观测和远程操作能力，以在2014年之前为大型结构系统提供新的地震工程研究测试能力。 该NEES设备站点将通过大学的vBNS连接连接到NEES合作实验室，具有千兆以太网功能。 通过NEES联盟协调共享使用的访问和培训。 该奖项是对提交给NSF 00-6“NEES：地震工程研究设备”项目招标的提案进行同行评审的结果。“根据这项裁决提供了下列设备：（1）三个100吨动态执行器，配备双400 gpm伺服阀，+/- 500 mm冲程，（2）两个200吨静态执行器，配备15 gpm伺服阀，+/- 500 mm冲程，（3）液压分配管线和歧管，（4）稳压罐和稳压器，（5）两个液压泵，每个液压泵185 gpm，用于连续操作，其沿着蓄能器组可以提供30秒的1600 gpm的最大流量，（6）数字控制系统，（7）用于静态和动态测试的测试控制包，（8）现有数据采集系统的升级和扩展，以适应远程观察，远程操作，远程传输和远程存储，（9）数据管理和处理系统，以适应实时系统、数据采集、存储、分发和分析，以及测试仪器，（10）用于远程观测和远程操作能力的设备，使得设备上的实验将通过高性能网络连接被观测和控制，（11）视频成像设备，最终目标是实时视频流，以及（12）传感器和测量设备。 该实验设施允许多种配置的全尺寸组件测试与实时数值模拟相结合，以研究大型结构系统的抗震性能，包括使用致动器，反应墙，坚固的地板和振动台（一个可移动）。 此外，该设备将用于开发新的混合测试算法，用于近全尺寸/大尺寸测试。 该大学已承诺400万美元，用于扩建和改善位于布法罗校园Ketter Hall的结构工程和地震模拟实验室的基础设施，以容纳升级后的新设备。 此次扩建包括一个新的研究实验室区域，具有坚固的地板和反应墙，控制室和用于培训和数据处理的办公室，服务区，存储和办公空间，以及一台新的40公吨起重机。 布法罗大学将把这种大规模、高性能的测试设备整合到其研究计划、本科和研究生课程中，通过现场课程为外部研究人员提供培训机会，接待访问学者，并开发基于网络的NEES设备远程操作模拟器。
