U.S.-Japan Joint Seminar: Post Peak Shear Failure of RC Piers Subjected to Cyclic Loading

9815558 Shing该奖项支持美国科学家参与美国- 1999年10月在日本山梨召开的循环荷载作用下钢筋混凝土桥墩峰值后剪切破坏日本研讨会。 协办机构包括科罗拉多大学博尔德分校的成培深教授及日本名古屋大学的田边忠昭教授。 研讨会将重点讨论钢筋混凝土桥墩的抗剪性能，这是一个重要的问题，涉及到桥梁结构在地震中的性能和安全性。 本次研讨会将提供一个论坛，讨论理论和试验上的峰值后剪切行为的钢筋混凝土柱，审查和总结国家的最先进的混凝土材料模型和分析方法，可用于模拟和理解钢筋混凝土柱的剪切行为，并确定未来的研究需求和可能的合作研究课题在这个问题上。合理和可靠的分析模型是必要的，以提高我们对钢筋混凝土桥墩的剪切性能的理解，以改善目前的抗震设计和改造方法，并允许现实的评估现有桥梁的地震安全性。 研讨会将围绕以下主题进行讨论：1）钢筋混凝土桥墩抗剪性能的理论、试验和现场观察，以及工程实践的需要; 2）混凝土材料的力学性能和建模以及有限元分析方法的最新发展; 3）钢筋混凝土桥梁的结构构件模型、系统分析和性能。研讨会的组织者作出了特别努力，让年轻的研究人员既参加研讨会，又作为观察员参加。 与日本专家在这一领域的想法和数据交流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。 预计研讨会结束后将编写和出版专题介绍。 该报告的提供将在地震工程研究所的通讯中公布。*

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.***
