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

9815558Shing该奖项支持美国科学家参加将于1999年10月在日本山梨市举行的关于循环荷载作用下RC桥墩尖峰后剪切破坏的美日研讨会。联合组织者是科罗拉多大学的Shi-shum Shing教授、博尔德教授和日本名古屋大学的Tanabe教授。研讨会将集中讨论钢筋混凝土桥墩的抗剪性能，这是关系到桥梁结构在地震中的性能和安全的重要问题。研讨会将提供一个论坛，讨论RC柱峰后抗剪性能的理论和试验，回顾和总结可用于模拟和理解RC柱抗剪性能的最新混凝土材料模型和分析方法，并确定该课题的未来研究需求和可能的合作研究课题。为了提高我们对钢筋混凝土桥墩抗剪性能的认识，改进现有的抗震设计和加固方法，以及对既有桥梁的抗震安全性进行现实的评估，需要合理可靠的分析模型。研讨会的讨论将围绕以下主题展开：1)钢筋混凝土桥墩剪切性能的理论、实验和现场观测，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；以及3)结构构件模型、系统分析和钢筋混凝土桥梁的性能。研讨会组织者做出了特别努力，让年轻的研究人员既作为参与者又作为观察员。与日本专家在这一领域交换想法和数据将使美国参与者能够推进他们自己的工作，并将为未来的合作项目奠定基础。研讨会结束后，预计将编写和出版专题介绍。这份报告的提供将在地震工程研究所的通讯上做广告。*

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.***
