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.
