NSF NEES MAST Lab Augmentation: Development of PsD Capabilities and Enhanced Display

该奖项为明尼苏达大学双子城分校（UMN）提供资金，用于升级乔治·e·布朗地震工程模拟网络（NEES）的实验能力，该网络是UMN的多轴子装配测试系统（MAST）设施，该设施将由NEES财团公司运营，在2005 - 2014财年期间作为国家共享使用设施。所要求的设备为UMN NEES站点提供伪动态测试能力，并根据站点访问团队的建议进行年度审查和对使用该设备站点感兴趣的地震工程研究人员的输入进行选择。工作范围包括开发一个本地伪动态服务器，该服务器将控制斜坡保持伪动态测试以及连续的伪动态测试。这些新增的功能将使NEES研究人员能够进行近实时测试和慢速连续伪动态测试，包括与MAST现有6自由度能力相结合的子结构测试。根据最初的合作协议CMS-0086602，该站点不提供此功能。该设备将通过NEES财团，公司，UMN NEES设施提供给地震工程研究界。该奖项由NSF NEES主要研究设备和设施建设（MREFC）项目资助，是国家减少地震灾害计划（NEHRP）的一个组成部分。

This award provides funding to the University of Minnesota - Twin Cities (UMN), to upgrade the experimental capabilities of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES), A System for Multi-Axial Sub-assemblage Testing (MAST) facility at UMN that will be operated by NEES Consortium, Inc., as a national shared use facility during FY 2005 - FY 2014. The requested equipment provides Pseudo-dynamic testing capability for the UMN NEES site, and was selected based on recommendations of the site visit teams for annual review and input from earthquake engineering researchers interested in using this equipment site. The scope of work includes developing a local pseudo-dynamic server that will control ramp-and-hold pseudo-dynamic testing as well as continuous pseudo dynamic testing. These added features will enable NEES researchers to conduct near Real-Time testing and slow continuous pseudo- dynamic testing including sub-structuring in conjunction with the existing 6-dof capability of MAST. This capability was not provided at this site under the original cooperative agreement CMS-0086602.This equipment will be available to the earthquake engineering research community through the NEES Consortium, Inc., UMN 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).
