Abstract

PI: Subhash Goel, University of Michigan The purpose of this research proposal is to seek NSF funding for: (1) travel support for a group of 10-12 invited US side participants to attend the International Workshop on Steel and Concrete Composite Construction in Seismic Regions (IWSCCC-2003) to be held at the National Center for Research on Earthquake 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 on October 2-7, 2003, and (2) to partially support a doctoral student to be able to continue analysis and design 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 new generation of performance-based design codes. The P.I.'s believe that this program is a good example indicative of the future trend when international cooperative research will become more common using globally networked facilities and modern information technology, including the NEES facilities currently being established in the US. Research Plan The proposed research is a follow up of Phase 5 of the US-Japan Cooperative Research Program on Composite and Hybrid Structures (1993-2000) where major emphasis was place on obtaining more basic knowledge through studies of components and sub-assemblages. In this current US-Taiwan Cooperative Program two full scale frames (RCS and CFT-BRB) are subjects of thorough study. The RCS frame study has been completed, and the study and testing of the CFT-BRBF is currently in progress. The proposed research proposal has two components. The first component involves carrying out pretest and post-test analyses and related design implication study of the CFT frame cooperatively with the Taiwan research team. The second component includes travel of a group of 10-12 US participants to attend the International Workshop on Steel and Concrete Composite Construction that will follow immediately after the testing of the CFT frame. The main purpose of the workshop is to create a forum of researchers, practitioners and constructors to discuss the recent developments and experiences as well as to explore the challenges and opportunities for further research and development of innovative composite and hybrid structures in the future. Broader Impact - Research: The research work will result in rational and well founded seismic modeling, analysis and performance-based design methodologies for advanced composite structures, which show promise of excellent structural efficiency and performance. That will accelerate the use of those structural systems in seismic design practice. The performance-based design and analysis methodologies 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 recommendations quickly in the future codes and practice. Broader Impact - Educational and International Cooperation: The research work in this project will constitute a major part of one doctoral student's research training and education. Therefore, the project will not only contribute to further advancement of the knowledge base and improvement in the professional practice and codes, but will also help in educating highly qualified professionals needed to carry out the earthquake hazard mitigation program in the future. Results from this project will also lead to important advances in inelastic modeling and design tools that are used in structural analysis and design courses. Additionally, the project will provide great opportunity for international cooperation and exchange of research personnel.
