Planning meetings for the second five years of NEES/E-Defense collaboration were held at the National Science Foundation, Arlington, VA, on January 12-13, 2009, and in Kobe, Japan on September 18-19, 2009. At the January 2009 meeting, an overall theme of "Enabling the Earthquake Resilient City" was adopted for the second five-year phase and high priority research topics were identified. One of these high-priority topics involves studies of the seismic design of high-performance reinforced concrete structures. At the follow-on September 2009 meeting in Kobe, E-Defense staff and Japanese university researchers presented an aggressive research plan that includes testing of two low-rise, large-scale, buildings, one conventional and one innovative, on the E-Defense shake table, the world's largest shake table, in October 2010. To meet this aggressive testing schedule, initial schematic and detailed design of the test specimens must be completed by mid October 2009 and February 2010, respectively, and drawings must be prepared by April 2010. Specimen construction and instrumentation are expected to occur during summer 2010 to enable October 2010 testing. These tests provide an exceptional opportunity for U.S. researchers to further knowledge on the seismic design of reinforced concrete structures, provided the test specimens include lateral force resisting systems with strength and details that are reasonably consistent with U.S. seismic design practice. Extensive discussions at the Kobe planning meeting produced a framework to address this issue, i.e., test specimens that would be of value to both U.S. and Japanese researchers and enable U.S.-Japan collaboration for the 2010 tests, as well as future tests both in Japan and in the U.S. through NSF-supported NEES research (NEESR) projects. This award enables U.S. researcher participation in the October 2010 E-Defense tests. This award supports schematic and final designs for the test specimens, analytical studies of the initial and final designs for specified hazard levels, and modest travel to support the proposed collaboration and enable robust collaboration through subsequent (potential) NSF-supported NEESR studies. This RAPID award will contribute to furthering U.S.-Japan collaboration in earthquake engineering by: (1) maintaining the tradition of strong U.S.-Japan research in the seismic design of reinforced concrete buildings, (2) creating a framework for productive future U.S.-Japan collaboration on high-performance reinforced concrete buildings, (3) establishing a mechanism for data exchange on E-Defense and NEESR projects, and (4) enabling future NEESR projects based on the large-scale E-Defense tests. Results of these studies will be posted on the http://www.nees.org web site as they are completed and widely publicized so that interested U.S. researchers will have access to information about these activities. Future studies could use data generated from the October 2010 tests for system level validation studies, as well as follow-on studies that investigate issues identified from the tests.

2009年1月12日至13日在弗吉尼亚州阿灵顿的国家科学基金会和2009年9月18日至19日在日本科比举行了NEES/电子防御合作第二个五年的规划会议。 在2009年1月的会议上，通过了第二个五年阶段的总主题“建设具有抗震能力的城市”，并确定了高度优先的研究课题。这些高优先级的主题之一涉及高性能钢筋混凝土结构的抗震设计的研究。 2009年9月在科比举行的后续会议上，E-Defense的工作人员和日本大学的研究人员提出了一项积极的研究计划，其中包括2010年10月在世界上最大的振动台E-Defense振动台上测试两座低层大型建筑物，一座是传统建筑物，另一座是创新建筑物。 为了满足这一积极的测试时间表，测试样本的初步示意图和详细设计必须分别在2009年10月中旬和2010年2月完成，图纸必须在2010年4月前准备好。预计在2010年夏季进行样品建造和仪器测试，以便在2010年10月进行测试。 这些试验为美国研究人员提供了一个极好的机会，以进一步了解钢筋混凝土结构的抗震设计，前提是试验样本包括具有与美国抗震设计实践合理一致的强度和细节的抗侧力系统。在科比计划会议上进行的广泛讨论产生了解决这一问题的框架，即，测试样本，这将是有价值的美国和日本的研究人员，使美国- 2010年的测试以及未来在日本和美国通过NSF支持的NEES研究（NEESR）项目进行的测试。该奖项使美国研究人员能够参与2010年10月的电子防御测试。 该奖项支持测试样本的示意图和最终设计，指定危害水平的初始和最终设计的分析研究，以及适度的旅行，以支持拟议的合作，并通过随后的（潜在的）NSF支持的NEESR研究实现强大的合作。 这一快速奖将有助于促进美国-日本在地震工程方面的合作：（1）保持美国强大的传统，日本在钢筋混凝土建筑抗震设计方面的研究，（2）为美国未来的生产力创造一个框架。日本在高性能钢筋混凝土建筑方面的合作，（3）建立电子防御和NEESR项目的数据交换机制，（4）基于大规模电子防御测试，使未来的NEESR项目成为可能。 这些研究的结果将在完成后公布在http://www.nees.org网站上，并广泛宣传，以便感兴趣的美国研究人员能够获得有关这些活动的信息。 未来的研究可以使用2010年10月测试产生的数据进行系统级验证研究，以及调查测试中发现的问题的后续研究。
