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.

拟建一个项目，结合土壤-结构相互作用对通用结构进行多 NEES 现场结构测试。 拟议项目的目标是提供一个真实的测试台应用程序，用于验证和扩展 NEESgrid 和 NEES 设备站点的组件以进行分布式仿真。拟议的项目将涉及三个 NEES 设备站点（利哈伊大学、伊利诺伊大学厄巴纳-香槟分校和 RPI）、NEES 系统集成商和国家超级计算机应用中心 (NCSA) 的合作。该测试台将由 I-10 圣莫尼卡高速公路模型组成。 该建筑在 1994 年北岭地震中受损。 每个设备站点都将容纳桥梁组件的物理模型，并使用 NCSA 并行计算设施对上部结构进行分析建模。使用混合测试方法，来自 NCSA 的命令位移将发送到每个设备站点的物理子结构，然后施加这些位移，并将测量的恢复力返回到 NCSA。 站点和 NCSA 之间的通信将涉及使用互联网以及 NEES 系统集成商开发的软件和协议。拟议项目利用了模拟的各个方面，其中包括 NEES 设备站点和 NEESgrid 的许多应用程序，包括：（1）动态加载下的高级分析岩土建模； (2) 动载下的高级分析结构建模； (3) 使用离心机进行先进的岩土测试； (4) 使用多自由度测试设施进行先进的结构测试。 Lehigh NEES 设备场将负责其中一个桥墩。该码头将在 Lehigh NEES 设备现场建造和测试。 Lehigh 还将参与桥梁结构的结构部件的分析建模，以便在项目的某些阶段结合分布式模拟进行分析模拟。拟议项目的结果将带来许多好处。 NEES 设备站点将受益于对当前为分布式测试而建立的软件和硬件的评估。 NEES 的数据存储库和远程呈现将付诸实践，使广大社区能够观察测试并观察 NEES 分布式仿真愿景最终得到实现和证明。 最后，该项目将有助于扩展地震工程综合实验分析模拟的最先进水平。
