This award will support a group of U.S. researchers to travel to Japan during 2016 and 2017 to continue a research collaboration with Japanese colleagues to develop and conduct a seismic testing program for two full-scale, ten-story reinforced concrete building models on the three-dimensional, full-scale earthquake testing shake table facility (E-Defense) operated by Japan's National Research Institute for Earth Science and Disaster Resilience. The first building model was tested during November and December 2015, and the second building model is planned to be tested during May 2017. By working with Japanese colleagues, the U.S. researchers will contribute to the design, instrumentation, and testing protocols of the building structures, and will gain access to the test data for use in subsequent research analyses. Subsequent studies using the data generated in these tests can help advance simulation methods for improving the seismic resilience of buildings and communities in the United States. The U.S. participants will be selected based on their expertise, as well as to promote participation from underrepresented groups. This award is part of the National Earthquake Hazards Reduction Program. Under NSF award CMMI-1547833, U.S. researchers participated in the seismic testing of the first ten-story building model on the E-Defense shake table during November and December 2015. The first building model had moment-resisting frames in one direction and shear walls in the orthogonal direction. The base of the structure was constructed first to study the effects of simple sliding devices on building response and then locked to create a fixed-based condition to enable testing to severe damage. The focus of this award is on the seismic design and testing of the second ten-story building model, which will be conceptually similar to the first structure, but with different design details. The second structure will be designed to have many features in common with U.S. reinforced concrete buildings, including moment frames and rectangular shear walls designed to withstand effects associated with the inelastic response of buildings subjected to strong earthquakes that drive the buildings to near collapse. For these second tests, the U.S. participants will aim to gather data that can serve as the basis for future research within the U.S., including research on computational models to simulate the response of buildings to strong earthquake shaking.

该奖项将支持一组美国研究人员在2016年和2017年期间前往日本，继续与日本同事进行研究合作，在日本国家地球科学与灾害恢复研究所运营的三维全尺寸地震测试震动台设施（E-Defense）上开发和实施两个全尺寸10层钢筋混凝土建筑模型的地震测试项目。第一个建筑模型在2015年11月和12月进行了测试，第二个建筑模型计划在2017年5月进行测试。通过与日本同事合作，美国研究人员将为建筑结构的设计、仪器和测试协议做出贡献，并将获得测试数据，用于后续的研究分析。使用这些测试中产生的数据的后续研究可以帮助改进模拟方法，以提高美国建筑物和社区的抗震能力。美国的参与者将根据他们的专业知识进行选择，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。根据NSF授予的CMMI-1547833，美国研究人员于2015年11月和12月在E-Defense振动台上参与了第一个10层建筑模型的地震测试。第一个建筑模型在一个方向上有抗弯矩框架，在正交方向上有剪力墙。首先建立结构的基础，研究简单滑动装置对建筑物响应的影响，然后锁定以创建固定的基础条件，以便进行严重损伤的测试。该奖项的重点是第二个十层建筑模型的抗震设计和测试，该模型将在概念上与第一个结构相似，但设计细节不同。第二种结构将被设计成与美国钢筋混凝土建筑有许多共同的特征，包括弯矩框架和矩形剪力墙，这些剪力墙的设计可以承受与建筑物遭受强烈地震的非弹性反应相关的影响，这些影响会使建筑物濒临倒塌。对于第二次测试，美国参与者的目标是收集数据，作为美国未来研究的基础，包括研究模拟建筑物对强烈地震反应的计算模型。
