Abstract0429276WillamThis award provides funding to the University of Colorado - Boulder (CU), to upgrade the experimental capabilities of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Fast Hybrid Test Platform for the Seismic Performance Evaluation of Structural Systems site that will be operated by NEES Consortium, Inc., as a national shared use facility during FY 2005 - FY 2014. The major equipment at the CU NEES site includes: (I) hydraulic equipment; (II) instrumentation package; (III) control, computation, data acquisition, and networking systems.Under this award, the following equipment will be purchased for this site: Data-Acquisition unit; LVD package; and a Reaction Wall system. To fully utilize Fast Hybrid Testing (FHT) techniques, a bi-directional reaction-wall system is proposed. The reaction-wall system will consist of a main reaction wall that is 4.1-m (13.5-ft.) long and 3.66-m (12-ft.) tall and two smaller walls in the orthogonal direction that are 2.29-m (7.5-ft.) long and 3.66-m (12-ft.) tall. The current DAQ allows only 48 channels to interface with the specimen. A supplemental data-acquisition unit will provide additional 56 data channels, and 16 LVDTs (Linear Variable Differential Transformers). This upgraded equipment including the reaction wall will utilize the FHT capabilities to its true potential at this NEES site. This equipment will be available to the earthquake engineering research community through the NEES Consortium, Inc., CU 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).

摘要0429276Willam该奖项为科罗拉多大学博尔德分校 (CU) 提供资金，以升级 George E. Brown, Jr. 地震工程模拟网络 (NEES) 结构系统抗震性能评估快速混合测试平台的实验能力，该平台将由 NEES Consortium, Inc. 运营，作为 2005 财年至 2014 财年期间的国家共享设施。 中大NEES现场主要设备包括：（一）液压设备； （二）仪器仪表包； (III) 控制、计算、数据采集和网络系统。根据该合同，将为该站点购买以下设备： 数据采集装置； LVD封装；和反应墙系统。为了充分利用快速混合测试（FHT）技术，提出了一种双向反应壁系统。反应墙系统将由一个长 4.1 米（13.5 英尺）、高 3.66 米（12 英尺）的主反应墙和两个正交方向的较小反应墙（长 2.29 米（7.5 英尺）、高 3.66 米（12 英尺））组成。当前的 DAQ 仅允许 48 个通道与样本连接。补充数据采集单元将提供额外的 56 个数据通道和 16 个 LVDT（线性可变差动变压器）。包括反应墙在内的升级设备将在该 NEES 站点充分发挥 FHT 功能的真正潜力。该设备将通过 NEES Consortium, Inc.、CU NEES 设施向地震工程研究界提供。 该奖项由 NSF NEES 主要研究设备和设施建设 (MREFC) 项目资助，是国家地震减灾计划 (NEHRP) 的一部分。
