A project is proposed to perform multi-NEES site structural testing of a common structure in conjunction with soil-structure interaction. The objective of the proposed project is to provide a realistic test bed application with which to verify and extend the components of the NEESgrid and the NEES equipment sites for distributed simulation. The proposed project will involve the collaboration of three NEES Equipment Sites (Lehigh University; University of Illinois at Urbana-Champaign; and RPI), the NEES System Integrator, and National Center for Supercomputer Applications (NCSA).The test bed will consist of a model of the I-10 Santa Monica Freeway. This structure was damaged during the 1994 Northridge earthquake. Each of the equipment sites will house a physical model of a component of the bridge, with the superstructure being modeled analytically using the NCSA parallel computing facility. Using hybrid testing methods, command displacements from NCSA will be issued to the physical substructures at each of the equipment sites, which in turn are imposed and the measured restoring forces returned to NCSA. Thecommunication between the sites and NCSA will involve the use of the Internet in conjunction with software and protocols developed by the NEES System Integrator.The proposed project utilizes aspects of simulation that comprise many of the applications of the NEES Equipment Sites and NEESgrid, including: (1) advanced analytical geotechnical modeling under dynamic loading; (2) advanced analytical structural modeling under dynamic loading; (3) advanced geotechnical testing using centrifuges; and (4) advanced structural testing using multi-degrees-of-freedom testing facilities. The Lehigh NEES Equipment Site will be responsible for one of the bridge piers. This pier will be built and tested at theLehigh NEES Equipment Site. Lehigh will also be involved in analytical modeling of structural components of the bridge structure to perform analytical simulations in conjunction with distributed simulation in some of the phases of the project.The results from the proposed project will offer numerous benefits. The NEES Equipment Sites will benefit from an evaluation of the software and hardware currently established for distributed testing. The data repository and telepresence for NEES will be put into action, enabling the general community to observe the tests and observe that the NEES vision of distributed simulation is finally realized and proven. Finally, the project will help to extend the state-of-the-art in integrated experimental-analytical simulation in earthquake engineering.

提出了一个项目，以与土壤结构相互作用结合使用共同结构的多层站点结构测试。 拟议项目的目的是提供一个逼真的测试床应用，以验证和扩展Neesgrid和Nees设备站点的组件进行分布式模拟。拟议的项目将涉及三个NEES设备网站（Lehigh University;伊利诺伊大学Urbana-Champaign；和RPI），NEES系统集成商和国家超级计算机应用中心（NCSA）（NCSA）。测试床将由一个。 I-10圣莫尼卡高速公路的模型。 在1994年的北山地震期间，这种结构损坏了。 每个设备站点都将容纳桥梁组件的物理模型，并使用NCSA并行计算设施对上层建筑进行分析建模。使用混合测试方法，将向每个设备站点的物理子结构发出来自NCSA的命令位移，然后将其施加，并将测量的恢复力返回到NCSA。 网站和NCSA之间的通信将涉及NEES系统集成商开发的软件和协议的结合。拟议的项目利用了构成NEES设备网站和NEESGRID的许多应用的各个方面，包括： 1）在动态载荷下进行高级分析岩土建模； （2）动态负载下的高级分析结构建模； （3）使用离心机进行高级岩土测试； （4）使用多度自由测试设施的高级结构测试。 Lehigh Nees设备站点将负责其中一个桥梁。该码头将在Thelehigh Nees设备网站上建造和测试。 Lehigh还将参与桥梁结构的结构组件的分析建模，以在项目的某些阶段进行分析模拟进行分析模拟。拟议项目的结果将提供许多好处。 NEES设备网站将受益于对目前用于分布式测试的软件和硬件的评估。 NEE的数据存储库和关注将采取行动，使总体社区能够观察测试，并观察到分布式模拟的NEE愿景最终被实现和证明。 最后，该项目将有助于扩展地震工程集成的实验分析模拟中的最先进。
