Researchers from Japan and the United States have been collaborating during the past two years on building tests to be conducted at the E-Defense shake table facility in Miki City, Japan, in December 2010, where two four-story, full-scale buildings will be tested side by side subjected to three dimensional seismic shaking. As the outcome of this international planning, U.S. researchers have the opportunity to provide additional sensors on the test specimens to enable measurement of more detailed building response during the tests. Through this award, the U.S. research team will provide additional sensors, cables, and data acquisition systems for the testing in addition to the 400 sensors being provided by the Japanese; the Japanese E-Defense staff will install the U.S. sensor mounts, sensors, and cables. This additional data will enable improved building model calibration and/or calibration for flexure and for shear-flexure interaction. Data obtained from these tests will be archived in the NEES Project Warehouse data repository (http://www.nees.org). This award also provides travel support for faculty and students to participate in the testing in Japan and process the data, and to continue collaboration with Japan on analytical building models.Intellectual Merit: These two building tests are each multi-million dollar tests and the United States currently does not have facilities to conduct such tests. These tests will provide data for the U.S. earthquake engineering community to learn about the behavior and response of three-dimensional buildings subjected to a range of ground motion intensities, including motions expected to produce near-collapse. The additional sensors will measure local response quantities to aid in the development and calibration of analytical models and to improve understanding of a very commonly used building system (internationally). Broader Impacts: This award is an outcome of active collaborations between Japanese and U.S. researchers on the instrumentation needed to record detailed response data that is critical to improve understanding of the seismic performance of building systems. The data will be archived in the NEES Project Warehouse and be publicly available for reuse by researchers and practitioners. Results of this research will be presented at major U.S. and international conferences.

在过去的两年中，来自日本和美国的研究人员在2010年12月在日本米基市的电子防御摇桌设施进行建筑测试，在那里进行建筑测试，那里将在那里进行两座四层四层全尺寸的建筑物，并在三二维地震摇动中并肩作战。作为这项国际计划的结果，美国研究人员有机会在测试标本上提供其他传感器，以便在测试过程中测量更详细的建筑响应。 通过该奖项，美国研究团队还将为测试提供其他传感器，电缆和数据采集系统，而日本人提供的400个传感器；日本电子防御人员将安装美国传感器座，传感器和电缆。 此附加数据将使改进的建筑模型校准和/或校准进行挠曲和剪切曲线相互作用。 从这些测试获得的数据将在NEES项目仓库数据存储库（http://www.nees.org）中存档。 该奖项还为教师和学生提供了旅行支持，以参加日本的测试并处理数据，并继续与日本在分析建筑模型上进行合作。智能优点：这两个建筑测试是数百万美元的测试，而美国目前没有进行此类测试的设施。这些测试将为美国地震工程社区提供数据，以了解遭受一系列地面运动强度的三维建筑物的行为和响应，包括预计会产生近崩溃的动议。 其他传感器将测量局部响应量，以帮助分析模型的开发和校准，并提高对非常常用的建筑系统（国际上）的理解。更广泛的影响：该奖项是日本和美国研究人员在记录详细响应数据所需的仪器上积极合作的结果，这对于提高对建筑系统的地震性能的理解至关重要。 数据将存档在NEES项目仓库中，并将公开可供研究人员和从业人员重复使用。这项研究的结果将在美国主要和国际会议上提出。
