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 biaxial multiple (3) shake table research equipment site at the University at Nevada Reno, Reno, Nevada. The University of Nevada Reno will design, construct, install, commission, and operate one new biaxial shake table and the upgrade of two existing shake tables for large-scale geotechnical and long, linear structural and lifeline 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 structural systems through 2014. This NEES equipment site will be connected to the NEES collaboratory through the high-performance Nevada Research Network that serves as the University's connection to Internet2's Abilene Network, 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) one new, relocatable, 4.3 x 4.5 m, 445 kN payload, +1 g, + 300 mm displacement (longitudinal and lateral) shake table, (2) upgrades to two existing, moveable, 445 kN shake tables from uniaxial to biaxial (longitudinal and lateral) capability, to be identical to the new table, (3) new hydraulic distribution lines, (4) new blowdown bank with the same capacity as the existing banks, (5) upgraded hydraulic power supply, by addition of a third pump (720 lpm), (6) digital control system for three tables, (7) expansion of existing data acquisition system to accommodate teleobservation, teleoperation, teletransmission, and telestorage, and (8) equipment for teleobservation and teleoperation capabilities so that experiments on the tables will be observable and controllable via high performance network connections. The facility will consist of three biaxial shake tables, which will be relocatable on the strong floor of the Large-Scale Structures Laboratory on the University of Nevada Reno campus. A variety of table configurations will be used to meet present and future research needs. Furthermore, each table may be operated independently of the other two tables, in-phase with the other two tables (thus forming a single large table), or differentially with the other two tables for the simulation of spatial variation effects in earthquake ground motions. The facility will be the only one of its kind in the United States and will enable next generation experiments to be conducted. These include studies of spatial variation in earthquake ground motion on critical extended-in-plan lifeline systems, the biaxial response of long structural systems and their components, and the behavior of very large-scale systems that are either physically too large for existing, single-table facilities, or too heavy, or both. Together the three tables can host specimens up to 1.35 MN in total weight, with the tables separated up to a maximum of 36 m centerline-to-centerline. The total cost of the equipment requested in this proposal is $7,017,200. The University has already obtained $2,618,750 towards this goal from the U.S Department of Energy ($1,000,000) and the U.S. Department of Housing and Urban Development ($1,618,750) reducing the budget request to NSF to $4,398,450. The University will integrate this shake table equipment into its research program, undergraduate and graduate assistantships and internships, high school summer camps, and K-12 outreach. The University will also provide training opportunities for outside researchers through on-site courses and workshops.

小乔治·布朗（George E. 根据NEES计划，该合作协议在内华达州内华达州内华达州里诺大学建立了NEE双轴多（3）摇桌研究设备。 内华达大学里诺大学将设计，构建，安装，佣金和操作一个新的双轴摇桌，并升级两个现有的摇桌，用于大规模的岩土工程学，较长的，线性的结构性和生命线地震工程实验。 该设备将在2004年或更早之前运行，并将作为国家共享的NEES设备网站管理，并具有远程观察和远程处理能力，以提供新的地震工程研究测试，直到2014年，大型结构系统。该NEES设备将与NEES与NEES合作连接到NEES NEES NEES网络，该网络与高等的Nevada Newernet网络相连，该网络与Intern Intern Intern Intern Intern Intern Internock Internock Internock Internock Internock and Internock Internock and Introgn Internoct and Intions 2功能。 共享使用访问和培训将通过NEES联盟进行协调。 该奖项是对计划征集NSF 00-6的提案的同行评审的结果，“ NEES：地震工程研究设备”。 该奖项下提供以下设备：（1）一个新的，可重新定位的4.3 x 4.5 m，445 kN有效载荷，+1 g， + 300 mm位移（纵向和侧面）摇桌，（2）升级到两个现有的，可移动的，可移动的445 kN摇台，从单十一型和较长的持续的桌子上，是新的（较长），是新的（较长的），是识别的，是识别的。 lines, (4) new blowdown bank with the same capacity as the existing banks, (5) upgraded hydraulic power supply, by addition of a third pump (720 lpm), (6) digital control system for three tables, (7) expansion of existing data acquisition system to accommodate teleobservation, teleoperation, teletransmission, and telestorage, and (8) equipment for teleobservation and teleoperation capabilities so that experiments on the tables可以通过高性能网络连接可观察到可控。 该设施将由三张双轴摇桌组成，它们可以在内华达大学里诺大学校园的大型结构实验室的强大地板上重新定位。 各种表配置将用于满足当前和未来的研究需求。此外，每个表可以独立于其他两个表格，并与其他两个表（从而形成单个大表），也可以与其他两个表差异化，以模拟地震地面运动中的空间变化效应。 该设施将是美国唯一同类设施，并将实现下一代实验。 其中包括研究地震地面运动在关键的扩展延长生命线系统上的空间变化，长结构系统及其组件的双轴反应以及非常大规模的系统的行为，这些系统在物理上来说对于现有的单台设施而言太大，或者是太重，或者是太重。 这三张桌子一起可以容纳总重量高达1.35 mn的样品，桌子分开最多36 m中心线至中心线。 该提案中要求的设备总成本为7,017,200美元。 该大学已经从美国能源部（1,000,000美元）和美国住房和城市发展部（1,618,750美元）获得了2,618,750美元的目标，将预算请求减少到4,398,450美元。 该大学将将这种摇桌设备纳入其研究计划，本科生和研究生助理和实习，高中夏令营以及K-12外展活动。 该大学还将通过现场课程和研讨会为外部研究人员提供培训机会。
