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 earthquake engineering shake table research equipment site at the University at Buffalo, The State University of New York, Buffalo, NY. The University at Buffalo will design, construct, install, commission, and operate two six degree of freedom (DOF) shake tables for geotechnical and structural earthquake engineering experimentation. This equipment 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 for large/full-scale and long span structures 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 will 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) upgrade of the existing 3.6 m x 3.6 m, 50 metric ton, shake table from 5 DOF to 6 DOF by adding a transverse DOF, (2) a new, movable 3.6 m x 3.6 m, 50 metric ton, 100 Hz shake table, (3) upgrade and expansion of the existing data acquisition system to accommodate teleobservation, teleoperation, teletransmission, and telestorage, (4) data management and processing system to accommodate real-time systems, data acquisition, storage, distribution and analysis, and test instrumentation, (5) equipment for teleobservation and teleoperation capabilities so that experiments on the equipment will be observable and controllable via high performance network connections, (6) video imaging equipment with the eventual goal of streaming real-time video, and (7) sensors and measurement devices. The new shake table can be rapidly repositioned from immediately adjacent to the existing shake table to 30 m linearly from it. Together these two tables can host specimens of up to 100 metric tons, as long as 36 m, and subjected to fully in-phase or totally uncorrelated dynamic excitations. 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 room 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 shake table 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NEES地震工程振动台研究设备场地。 布法罗大学将设计、建造、安装、调试和操作两个六自由度（DOF）振动台，用于岩土和结构地震工程实验。 该设备将于2004年或更早投入使用，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，以便在2014年之前为大型/全尺寸和长跨度结构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。 共享使用的访问和培训将通过NEES联盟进行协调。 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。" 根据这一合同提供了下列设备：（1）通过增加横向自由度，将现有的3.6 m x 3.6 m，50公吨，振动台从5个自由度升级到6个自由度，（2）一个新的，可移动的3.6 m x 3.6 m，50公吨，100 Hz振动台，（3）升级和扩展现有的数据采集系统，以适应远程观测，远程操作、远程传输和远程存储，（4）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，（5）用于远程观察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可观察和可控制，（6）视频成像设备，最终目标是实时视频流，以及（7）传感器和测量设备。 新的振动台可以从紧邻现有振动台的位置快速重新定位到距离现有振动台30 m的直线位置。这两个振动台可以承载长达36 m、重达100吨的试件，并承受完全同相或完全不相关的动态激励。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振动台设备整合到其研究计划和本科生和研究生课程中，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。
