U.S.-Japan Joint Seminar: Finite Element Anaylsis of Reinforced Concrete/June 1991/New York, New York

该奖项支持10名美国科学家参加美日联合举办的“钢筋混凝土有限元分析”研讨会。钢筋混凝土的力学行为，特别是其动力性能的模拟，是一个极其重要的领域。对某些特殊结构的需求正在增加，例如核电站设施和海上钻井平台，因此越来越需要一种更全面的分析工具来帮助设计这种结构。有限元方法的发展使分析各种不同类型的结构成为可能，并使其几何建模更加逼真，从而使研究人员对钢筋混凝土结构的行为有了新的认识。美国和日本科学家在这一领域的研究是互补的，美国的研究人员为有限元方法的进步做出了非常宝贵的基本贡献，而日本的研究人员在将这些进步转化为实践方面要积极得多。因此，研讨会既应该有助于记录每个国家的最新进展，也应该有助于将新技术开发成实践，特别是在美国。研讨会将于1991年6月3日至6日在纽约哥伦比亚大学举行。联合主办方是哥伦比亚大学土木工程与工程力学系的Christian Meyer教授和日本千叶大学建筑工程系的野口浩教授。研讨会将分为两部分，第一部分集中于最新技术，第二部分集中于验证和应用于实际工程问题。研讨会将讨论的具体议题包括(1)本构模型；(2)断裂力学；(3)钢筋混凝土模型；(4)随时间变化的行为和在动态载荷下的行为；以及(5)计算方面。这将是美日合作科学计划下关于这一主题的第二次研讨会，第一次是在1985年举行的。预计这次研讨会与第一次研讨会一样，将导致更多的信息交流和更广泛的研究协作。

This award provides support for the participation of ten US scientists in a joint US-Japan seminar on "Finite Element Analysis of Reinforced Concrete". The modelling of the behavior of reinforced concrete, particularly its dynamic behavior, is an extremely important field. Increased demands are being placed on certain special structures, such as nuclear power plant facilities and offshore drilling platforms, and hence there is a growing need for a more comprehensive analysis tool to aid in the design of such structures. The development of the finite element method has made it possible to analyze many different kinds of structures and to model their geometry more realistically, thus enabling researchers to gain new insights into the behavior of reinforced concrete structures. The research undertaken by US and Japanese scientists in this area is complementary, US researchers having made very valuable basic contributions to the advancement of finite element methods while Japanese researchers having been much more active in transferring those advances into practice. The seminar should therefore contribute both to the documentation of recent advances in each country, and to getting new techniques being developed into practice, particularly in the US. The seminar is to be held on June 3-6, 1991 at Columbia University, New York. The co-organizers are Professor Christian Meyer, Department of Civil Engineering and Engineering Mechanics, Columbia University, and Professor Hiroshi Noguchi, Department of Architectural Engineering, Chiba University, Japan. The seminar will be divided into two parts, the first part concentrating upon the state of the art and the second on verification and application to practical engineering problems. Specific topics to be discussed at the seminar include (1) constitutive models; (2) fracture mechanics; (3) reinforced concrete models; (4) time-dependent behavior and behavior under dynamic loading; and (5) computational aspects. This will be the second seminar on this subject under the U.S.-Japan Cooperative Science Program, the first being held in 1985. It is expected that this seminar, as with the first seminar, will lead to increased exchanges of information and more extensive research collabor- ation.
