This award will support travel to Japan during August and December 2015 for four U.S. researchers to meet with Japanese collaborators to develop a seismic testing program for two full-scale, ten-story reinforced concrete building models. The building models will be tested for seismic performance on the E-Defense shake table operated by Japan's National Research Institute for Earth Science and Disaster Prevention (NIED). The cost for these shake table tests will be supported by a NIED research project. By working with Japanese researchers, the U.S. researchers will contribute to the design and testing of the structures, and will gain access to the test data to use in subsequent research analyses. The data will serve the U.S. national need of improving the resilience of buildings and communities against future earthquakes. The U.S. participants will be selected to best represent the research subject, as well as to promote participation from underrepresented groups. This award is part of the National Earthquake Hazards Reduction Program. This collaboration will be the second phase of a two-phase U.S.-Japan research collaboration on the seismic performance of reinforced concrete buildings tested on the E-Defense shake table. In 2009-2010, researchers from Japan and the U.S. completed the first phase, which included the design, planning, seismic testing on the E-Defense shake table, and post-test analyses of two four-story buildings, one of conventional reinforced concrete and another of post-tensioned concrete. The second phase of this collaboration will involve the seismic design and testing on the E-Defense shake table of two full-scale, ten-story reinforced concrete buildings. The first test is planned for December 2015. In preparation for the December testing, a team of four U.S. researchers will travel to Japan during August and December 2015 to meet with Japanese collaborators. In these joint meetings with Japanese collaborators, the U.S. team will participate in design and testing of the structures so as to maximize the lessons learned for both Japan and the U.S. The test structures will have many features in common with U.S. reinforced concrete buildings, including moment frames and rectangular shear walls designed to withstand effects associated with inelastic response of buildings subjected to strong earthquakes that drive the buildings to near collapse. Seismic isolation will also be considered. The U.S. participants will aim to gather data that can serve as the basis for future research by U.S. investigators, including research on computational models to simulate response of buildings to strong earthquake shaking.

该奖项将支持四名美国研究人员于2015年8月和12月前往日本，与日本合作者会面，为两个全尺寸、10层钢筋混凝土建筑模型开发地震测试项目。这些建筑模型将在由日本国家地球科学与防灾研究所（NIED）运营的E-Defense震动台上进行抗震性能测试。这些振动台试验的费用将由美国国家环境与发展研究所的一个研究项目资助。通过与日本研究人员合作，美国研究人员将为这些结构的设计和测试做出贡献，并将获得测试数据，以便在随后的研究分析中使用。这些数据将满足美国提高建筑物和社区抵御未来地震的弹性的国家需求。美国的参与者将被挑选为最能代表研究主题的人，并促进代表性不足的群体的参与。该奖项是国家减少地震灾害计划的一部分。这项合作将是美日两阶段研究合作的第二阶段，研究在E-Defense震动台上测试的钢筋混凝土建筑物的抗震性能。2009年至2010年，来自日本和美国的研究人员完成了第一阶段，包括设计、规划、E-Defense震动台的地震测试，以及对两座四层建筑的后测试分析，一栋是传统钢筋混凝土，另一栋是后张混凝土。该合作的第二阶段将涉及两个全尺寸、十层钢筋混凝土建筑的E-Defense振动台的抗震设计和测试。第一次测试计划于2015年12月进行。为了准备12月的测试，一个由四名美国研究人员组成的团队将于2015年8月和12月前往日本，与日本合作者会面。在这些与日本合作者的联合会议中，美国团队将参与结构的设计和测试，以便最大限度地为日本和美国吸取经验教训。测试结构将与美国钢筋混凝土建筑有许多共同之处，包括弯矩框架和矩形剪力墙，其设计可承受与建筑物遭受强烈地震的非弹性反应相关的影响，使建筑物接近倒塌。还将考虑隔震。美国参与者的目标是收集数据，作为美国调查人员未来研究的基础，包括研究模拟建筑物对强烈地震反应的计算模型。
