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.

这项研究建议的目的是为以下方面寻求NSF资金：(1)为受邀参加2003年10月8-9日在台湾台北国家地震工程研究中心(NCREE)举行的地震区钢与混凝土组合建筑国际研讨会(IWSCCC-2003)的10-12名美方受邀与会者提供差旅支持，同时进行全尺寸三层CFT屈曲约束支撑(BRB)框架的拟动力试验。以及(2)部分支持博士生在全面测试之前和之后与NCREE研究团队共同进行分析和设计研究。将制定分析/设计方法，以便纳入新一代基于性能的设计规范。S认为，这个项目是一个很好的例子，表明了未来的趋势，即国际合作研究将变得更加普遍，使用全球联网的设施和现代信息技术，包括目前在美国研究计划中建立的NEES设施。拟议的研究是美日复合材料和混合结构合作研究计划(1993年-2000年)第五阶段的后续行动，该阶段的主要重点是通过研究部件和子组装获得更多的基础知识。在目前的美台合作计划中，两个完整的框架(RCS和CFT-BRB)是深入研究的对象。RCS框架研究已经完成，CFT-BRBF的研究和试验目前正在进行中。拟议的研究提案包括两个部分。第一部分是与台湾研究团队合作，对钢管混凝土框架进行前、后测试分析及相关设计启示研究。第二部分包括10-12名美国学员参加即将在钢管混凝土框架测试后立即举行的钢和混凝土组合结构国际研讨会的旅费。研讨会的主要目的是为研究人员、实践者和施工者创建一个论坛，讨论最新的发展和经验，并探索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。广泛的影响-研究：研究工作将导致合理和有根据的先进复合材料结构的抗震建模、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使用。本研究开发的基于性能的设计和分析方法将通过对全尺寸结构的测试进行验证，从而说服专业和代码编写机构在未来的规范和实践中迅速纳入建议。广泛影响-教育和国际合作：该项目的研究工作将成为博士生研究、培训和教育的主要部分。因此，该项目不仅将有助于进一步完善知识库，完善专业实践和规范，而且将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。该项目的成果还将在结构分析和设计课程中使用的非弹性建模和设计工具方面取得重要进展。此外，该项目还将为国际合作和研究人员交流提供巨大的机会。
