This action funds Tea Visnjic of University of California at Berkeley to conduct a research project in Engineering during the summer of 2013 at Tongji University in Shanghai, China. The project title is "Earthquake Response of Tall Buildings Equipped with Seismic Damper Devices." The host scientists are Prof. Xilin Lu and Prof. Ying Zhou.The project aims to assess the dynamic response of tall reinforced concrete frame-type buildings equipped with seismic dampers. Damper devices help mitigate earthquake-induced movement of buildings, which can potentially lead to smaller damage. Tall reinforced concrete frames are particularly vulnerable to high post-earthquake reparation costs and prolonged disruption of occupancy due to repairs. The use of damper devices in these buildings may be able to significantly improve seismic performance, but such applications have been limited partly due to limited understanding of the effects of supplemental damping in seismic applications to tall concrete frames. Because tall reinforced concrete frame buildings are commonly constructed in both China and the seismically active parts of the United States, an improved understanding of supplemental damping effects on seismic behavior of such systems is beneficial to design practices in both countries. The planned study quantifies the effects of damper application on structural response of these buildings and identifies damper systems that most effectively achieve improvements in earthquake performance.Broader impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce. Furthermore, the proposed collaboration between researchers from the two universities with established records of intellectual contribution to seismic hazard reduction is motivated by the value in exchanging diverse ideas, complementing research and invaluable experience from past earthquakes. The study opens the door for future partnerships between the two institutions and contributes to global advancement in efforts to protect human life and economic well-being from natural disasters.

这一行动资助了加州大学伯克利分校的Tea Visnjic于2013年夏天在中国上海同济大学进行工程研究项目。 该项目的题目是“装有减震装置的高层建筑的地震反应”。“主持科学家为卢锡林教授及周颖教授，该项目旨在评估装有地震阻尼器的高层钢筋混凝土框架式建筑物的动力反应。阻尼装置有助于减轻地震引起的建筑物移动，这可能导致较小的损害。高层钢筋混凝土框架特别容易受到地震后高昂的修复费用和因维修而长期中断的影响。在这些建筑物中使用阻尼器装置可能能够显著地改善抗震性能，但是这样的应用受到限制，部分原因是对高层混凝土框架的抗震应用中的补充阻尼的效果的理解有限。 由于高层钢筋混凝土框架建筑在中国和美国地震活跃地区都很常见，因此，更好地了解附加阻尼对此类系统抗震性能的影响对两国的设计实践都是有益的。 计划中的研究将量化阻尼器应用对这些建筑物结构响应的影响，并确定最有效地实现地震性能改善的阻尼器系统。EAPSI奖学金的更广泛影响包括为研究员提供美国以外的第一手研究经验;介绍各自所在地的科学，科学政策和科学基础设施;以及社会，文化和语言的方向。 这些活动符合美国国家科学基金会的目标，即在科学家、工程师和教育工作者职业生涯的早期进行国际合作教育，从而确保美国科学劳动力具有全球意识。 此外，这两所大学的研究人员之间拟议的合作具有减少地震灾害的知识贡献的记录，其动机是交流不同的想法，补充研究和过去地震的宝贵经验。 该研究为两个机构之间未来的伙伴关系打开了大门，并有助于在保护人类生命和经济福祉免受自然灾害影响的努力方面取得全球进展。
