International Travel Support during 2015 for U.S.-Japan Research Collaboration on the Seismic Design and Testing of Mid-Rise Reinforced Concrete Buildings

该奖项将支持四名美国研究人员于2015年8月至12月前往日本与日本合作者会面，为两个全尺寸的十层钢筋混凝土建筑模型开发地震测试计划。 这些建筑模型将在日本国家地球科学和灾害预防研究所（NIED）运营的E-Defense振动台上进行抗震性能测试。这些振动台测试的费用将由NIED研究项目提供支持。通过与日本研究人员合作，美国研究人员将为结构的设计和测试做出贡献，并将获得测试数据，用于后续的研究分析。 这些数据将满足美国提高建筑物和社区抵御未来地震的能力的需求。美国参与者将被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。 这一合作将是美国两阶段合作计划的第二阶段，日本E-Defense振动台上钢筋混凝土建筑抗震性能测试研究合作项目。 在2009-2010年，来自日本和美国的研究人员完成了第一阶段，其中包括设计，规划，E-Defense振动台的地震测试，以及两个四层建筑的测试后分析，一个是传统的钢筋混凝土建筑，另一个是后张混凝土建筑。 此次合作的第二阶段将涉及两座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，包括抗弯框架和矩形剪力墙，其设计用于承受与遭受强烈地震的建筑物的非弹性响应相关的影响，使建筑物濒临倒塌。还将考虑地震隔离。美国参与者将收集数据，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震动反应的计算模型。

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.
