SGER: Multi-Site Soil-Structure-Foundation Interaction Test (MISST)

提出了一个结合土-结构相互作用对一种常见结构进行多NEES现场结构试验的项目。拟议项目的目标是提供一个现实的试验台应用程序，用来验证和扩展NEES网格和NEES设备站点的组件，以进行分布式模拟。拟议的项目将涉及NEES的三个设备点(利哈伊大学、伊利诺伊大学香槟分校和RPI)、NEES系统集成商和国家超级计算机应用中心(NCSA)的协作。试验台将由I-10圣莫尼卡高速公路的模型组成。这座建筑在1994年的北岭地震中遭到破坏。每个设备点将容纳桥梁组件的物理模型，上层建筑使用NCSA并行计算设施进行分析建模。使用混合测试方法，来自NCSA的命令位移将被发布到每个设备现场的物理子结构，这些子结构依次被施加，并将测量的恢复力返回给NCSA。各站点与NCSA之间的通信将涉及使用因特网以及NEES系统集成商开发的软件和协议。拟议的项目利用了模拟方面的内容，其中包括NEES设备场地和NEES网格的许多应用，包括：(1)动态加载下的高级分析性岩土建模；(2)动态加载下的高级分析结构建模；(3)使用离心机的高级岩土测试；以及(4)使用多自由度测试设施的高级结构测试。利哈伊NEES设备现场将负责其中一个桥墩。该码头将在利哈伊NEES设备现场建造和测试。利哈伊还将参与桥梁结构的结构组件的分析建模，以便在项目的一些阶段结合分布式模拟执行分析模拟。拟议项目的结果将带来许多好处。国家环境监测系统各设备点将受益于对目前为分布式测试建立的软件和硬件的评价。NEES的数据储存库和远程临场感将投入使用，使普通社区能够观察测试并观察到NEES的分布式仿真愿景最终实现和验证。最后，该项目将有助于扩展地震工程中综合实验-分析模拟的最新水平。

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.
