RAPID for NEES and E-Defense Collaboration: U.S. Instrumentation and Data Processing for the Four-Story Reinforced Concrete and Post-Tensioned E-Defense Building Tests

来自日本和美国的研究人员在过去两年里一直在合作进行建筑测试，测试将于2010年12月在日本三木市的E-Defense振动台设施进行，在那里，两座四层的全尺寸建筑将在三维地震震动下并排进行测试。作为这一国际计划的结果，美国研究人员有机会在测试样本上提供额外的传感器，以便在测试期间测量更详细的建筑响应。通过这一合同，美国研究团队将在日本提供的400个传感器之外，为测试提供额外的传感器、电缆和数据采集系统；日本电子防务人员将安装美国的传感器支架、传感器和电缆。这些额外的数据将改进建筑模型校准和/或弯曲和剪切-弯曲相互作用的校准。从这些测试中获得的数据将被归档到NEES项目仓库数据储存库(http://www.nees.org).该奖项还为教职员工和学生提供旅行支持，让他们参与日本的测试并处理数据，并继续与日本在分析建筑模型方面进行合作。智力上的优点：这两个建筑测试都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界提供数据，以了解三维建筑在一系列地面运动强度下的行为和反应，包括预计会产生接近倒塌的运动。额外的传感器将测量当地的响应量，以帮助开发和校准分析模型，并增进对(国际上)非常常用的建筑系统的了解。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方面积极合作的结果，该仪器对于提高对建筑系统抗震性能的了解至关重要。这些数据将被存档在NEES项目仓库中，并公开可供研究人员和从业人员重新使用。这项研究的结果将在美国和国际的主要会议上公布。

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.
