9815558ShingThis award supports the participation of American scientists in a U.S.-Japan seminar on Post Peak Shear Failure of RC Piers Subjected to Cyclic Loading, to be held in Yamanashi, Japan, in October, l999. The co-organizers are Professors Pui-Shum Shing at the University of Colorado, Boulder and Tada-aki Tanabe at Nagoya University in Japan. The seminar will focus on the shear behavior of reinforced concrete (RC) bridge piers, which is an important issue pertaining to the performance and safety of bridge structures during earthquakes. The seminar will provide a forum to discuss theory and experiments on the post-peak shear behavior of RC columns, to review and summarize the state-of-the-art concrete material models and analytic methods that can be used to simulate and understand the shear behavior of RC columns, and to identify future research needs and possible cooperative research topics on this subject. Rational and reliable analytic models are needed to enhance our understanding of the shear behavior of RC piers, to improve current seismic design and retrofit methods, and to permit a realistic assessment of the seismic safety of existing bridges. Discussion at the seminar will be structured around the following topics: 1) theory, experimental and field observations of the shear behavior of RC piers, and the needs in engineering practice; 2) mechanical behavior and modeling of concrete materials and recent developments in finite element analysis methods; and 3) structural component models system analysis and behavior of RC bridges. Seminar organizers have made a special effort to involve younger researchers as both participants and observers. The exchange of ideas and data with Japanese experts in this field will enable U.S. participants to advance their own work, and will set the stage for future collaborative projects. Following the seminar, it is anticipated that the presentations will be prepared and published. The availability of this report will then be advertised in the Newsletter of the Earthquake Engineering Research Institute.***

9815558Shing 该奖项支持美国科学家参加 1999 年 10 月在日本山梨县举行的美日研讨会，主题是循环荷载作用下的钢筋混凝土桥墩峰值剪切破坏。 协办者是科罗拉多大学博尔德分校的 Pui-Shum Shing 教授和日本名古屋大学的 Tada-aki Tanabe 教授。 研讨会将重点讨论钢筋混凝土（RC）桥墩的剪切性能，这是与地震期间桥梁结构的性能和安全性相关的重要问题。 该研讨会将提供一个论坛来讨论钢筋混凝土柱峰后剪力行为的理论和实验，回顾和总结可用于模拟和理解剪力的最先进的混凝土材料模型和分析方法RC 列的行为，并确定该主题的未来研究需求和可能的合作研究主题。需要合理可靠的分析模型来增强我们对钢筋混凝土桥墩剪切性能的理解，改进当前的抗震设计和改造方法，并对现有桥梁的抗震安全性进行现实评估。 研讨会的讨论将围绕以下主题进行：1）钢筋混凝土桥墩抗剪性能的理论、实验和现场观察，以及工程实践的需求； 2）混凝土材料的力学行为和建模以及有限元分析方法的最新发展； 3）结构部件模型系统分析和钢筋混凝土桥梁的性能。研讨会组织者特别努力让年轻研究人员作为参与者和观察员。 与该领域的日本专家交流想法和数据将使美国参与者能够推进自己的工作，并为未来的合作项目奠定基础。 研讨会结束后，预计将准备并出版演示文稿。 该报告的可用性将在地震工程研究所的通讯中发布。***
