PI: Subhash Goel， University of michigan本研究计划的目的是为以下项目寻求NSF资助：(1)为应邀参加2003年10月8-9日在台湾台北国家地震工程研究中心（NCREE）举行的“震区钢与混凝土复合结构国际研讨会”（IWSCCC-2003）的10-12人小组提供旅行支持，并于2003年10月2-7日对全尺寸3层复合CFT-屈曲约束支撑（BRB）框架进行伪动力测试；(2)部分支持博士生能够在全尺寸测试前后与NCREE研究团队共同进行分析和设计研究。将制订的分析/设计方法，以纳入新一代以性能为本的设计守则。侦探我们相信这个项目是一个很好的例子，表明了未来的趋势，即国际合作研究将越来越普遍，使用全球联网设施和现代信息技术，包括目前在美国建立的NEES设施。研究计划拟议的研究是美日复合材料和混合结构合作研究计划（1993-2000）第五阶段的后续研究，该阶段的主要重点是通过研究组件和子组件获得更多的基础知识。在当前的美台合作项目中，两个全尺寸框架（RCS和CFT-BRB）是深入研究的主题。TheRCS框架研究已经完成，CFT-BRBF的研究和测试目前正在进行中。拟议的研究计划有两个组成部分。第一部分是与台湾研究团队合作进行CFT框架的前测和后测分析及相关设计蕴涵研究。第二个组成部分包括一个由10-12名美国参与者组成的小组，在CFT框架测试后立即参加钢铁和混凝土复合结构国际研讨会。研讨会的主要目的是为研究人员、实践者和建设者创造一个论坛，讨论最近的发展和经验，并探讨未来创新复合材料和混合结构进一步研究和发展的挑战和机遇。更广泛的影响-研究：这项研究工作将为先进的复合材料结构提供合理和有根据的地震建模、分析和基于性能的设计方法，这些方法显示出优异的结构效率和性能。这将加速这些结构体系在抗震设计实践中的应用。本研究中开发的基于性能的设计和分析方法将通过在全尺寸结构上进行测试来验证，从而说服专业人员和代码编写机构将建议迅速纳入未来的代码和实践中。更广泛的影响-教育和国际合作：该项目的研究工作将构成博士生研究培训和教育的重要组成部分。因此，该项目不仅有助于进一步发展知识基础，提高专业实践和规范，而且有助于培养未来实施地震减灾计划所需的高素质专业人员。这个项目的结果也将导致非弹性建模和设计工具的重要进展，这些工具将用于结构分析和设计课程。此外，该项目将为研究人员的国际合作和交流提供很大的机会。

PI: Subhash Goel, University of MichiganThe purpose of this research proposal is to seek NSF funding for: (1) travel support for a group of 10-12invited US side participants to attend the International Workshop on Steel and Concrete CompositeConstruction in Seismic Regions (IWSCCC-2003) to be held at the National Center for Research onEarthquake Engineering (NCREE), Taipei, Taiwan, on October 8-9, 2003, in conjunction with Pseudo-Dynamic Testing of a Full Scale 3-Story composite CFT- Buckling Restrained Braced (BRB) Frame onOctober 2-7, 2003, and (2) to partially support a doctoral student to be able to continue analysis anddesign studies jointly with the NCREE research team prior to and after the full scale test. The analysis/design methodologies to be developed will be formulated for incorporation in the newgeneration of performance-based design codes. The P.I.'s believe that this program is a good exampleindicative of the future trend when international cooperative research will become more common usingglobally networked facilities and modern information technology, including the NEES facilitiescurrently being established in the US.Research PlanThe proposed research is a follow up of Phase 5 of the US-Japan Cooperative Research Program onComposite and Hybrid Structures (1993-2000) where major emphasis was place on obtaining morebasic knowledge through studies of components and sub-assemblages. In this current US-TaiwanCooperative Program two full scale frames (RCS and CFT-BRB) are subjects of thorough study. TheRCS frame study has been completed, and the study and testing of the CFT-BRBF is currently inprogress. The proposed research proposal has two components. The first component involves carryingout pretest and post-test analyses and related design implication study of the CFT frame cooperativelywith the Taiwan research team. The second component includes travel of a group of 10-12 USparticipants to attend the International Workshop on Steel and Concrete Composite Construction thatwill follow immediately after the testing of the CFT frame. The main purpose of the workshop is tocreate a forum of researchers, practitioners and constructors to discuss the recent developments andexperiences as well as to explore the challenges and opportunities for further research anddevelopment of innovative composite and hybrid structures in the future.Broader Impact - Research: The research work will result in rational and well founded seismicmodeling, analysis and performance-based design methodologies for advanced composite structures,which show promise of excellent structural efficiency and performance. That will accelerate the use ofthose structural systems in seismic design practice. The performance-based design and analysismethodologies as developed in this research will have been validated by testing on full size structures,thereby convincing the profession and the code writing bodies to incorporate the recommendationsquickly in the future codes and practice.Broader Impact - Educational and International Cooperation: The research work in this project willconstitute a major part of one doctoral student's research training and education. Therefore, the projectwill not only contribute to further advancement of the knowledge base and improvement in theprofessional practice and codes, but will also help in educating highly qualified professionals needed tocarry out the earthquake hazard mitigation program in the future. Results from this project will alsolead to important advances in inelastic modeling and design tools that are used in structural analysisand design courses. Additionally, the project will provide great opportunity for internationalcooperation and exchange of research personnel.
