RAPID: NEES and E-Defense Collaboration for E-Defense Shake Table Tests of High Performance Reinforced Concrete Buildings in 2010

NEES/E-Defense合作的第二个五年计划会议分别于2009年1月12日至13日和9月18日至19日在弗吉尼亚州阿灵顿的国家科学基金会和日本神户举行。在2009年1月的会议上，第二个五年阶段的总体主题为“建设抗震城市”，并确定了优先研究课题。其中一个高优先级的课题涉及高性能钢筋混凝土结构的抗震设计研究。在2009年9月于神户举行的后续会议上，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E-Defense振动台上测试两座低层大型建筑，一座是传统的，一座是创新的。为了满足这一严格的测试计划，测试样品的初步原理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月准备好。样品构造和仪器预计在2010年夏季进行，以便在2010年10月进行测试。这些测试为美国研究人员提供了一个难得的机会，进一步了解钢筋混凝土结构的抗震设计，前提是测试样本包括强度和细节与美国抗震设计实践合理一致的抗侧力系统。在神户规划会议上进行的广泛讨论产生了一个解决这一问题的框架，即，对美国和日本的研究人员都有价值的测试样本，并使美日合作能够进行2010年的测试，以及通过nsf支持的NEES研究（NEESR）项目在日本和美国进行的未来测试。该合同使美国研究人员能够参与2010年10月的E-Defense测试。该奖项支持测试样品的方案和最终设计，对指定危险级别的初始和最终设计进行分析研究，以及适度的旅行，以支持拟议的合作，并通过后续（潜在的）nsf支持的NEESR研究实现强大的合作。该RAPID奖将通过以下方式促进美日在地震工程方面的合作：(1)保持美日在钢筋混凝土建筑抗震设计方面的强大研究传统；(2)为未来美日在高性能钢筋混凝土建筑方面的富有成效的合作创建框架；(3)建立E-Defense和NEESR项目的数据交换机制；(4)基于大规模E-Defense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，并广泛公布，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，以及调查从测试中确定的问题的后续研究。

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.
