2017年3月　地震・火山グループ研究会

*日時：2017年3月31日（金）15:30-17:30*
会場：京都大学宇治キャンパス　*宇治おうばくプラザ・きはだホール*

【プログラム】
_退職記念講演 _*15:30-16:10 **Twenty Nine Years of Life as An Educator*
*中島正愛先生（地震防災研究部門・耐震機構研究分野　教授）*
I hereby wish to summarize how I have interacted with students and post-docs, both in Japan and overseas, what research outputs those students and junior colleagues have produced, and how I enjoy the interaction with them.  I also briefly touch upon my commitments, both past and present, on managing activities for the running of a few research and professional institutions.  In between, I show photos that are reminiscent my old friendships.

_特別記念講演 _*16:15-16:40 **Robustness of Steel-Concrete Composite Frames*
*Riccardo Zandonini (Professor, University of Trento, Italy)*
Vulnerability of structures to progressive collapse and mitigation of the effects of local damages are issues widely discussed. Recent events pointed out the need of new criteria aiming to design robust structures, i.e. structures for which a local failure does not lead to disproportionate effects. The main outcomes of recent studies are here briefly illustrated; the approaches recommended by the standards are then reviewed. Finally, the work carried out within European research projects is discussed, with particular reference to full scale tests of composite sub-frames aiming to provide an insight into the 3D action.

*16:40-17:05 **Seismic Performance of Braced Frame Systems*
*Chales W. Roeder (Professor, University of Washington, USA)*
Braced frames are widely used for resisting lateral loads due to wind and earthquake.  While Japanese engineers do consider their structures braced frames, engineers in other countries regard many Japanese structures as braced frames.  The presentation will discuss recent research on the seismic performance of braced frames and the factors affecting this performance. It will be shown that connections may vary widely, but these connections have a significant impact on the seismic performance. The presentation will discuss both braced frames with buckling restrained and buckling braces.

*17:05-17:30 **Community Resilience: The Impact of Dr. M. Nakashima's Work Worldwide*
*Roberto T. Leon (Professor, Virginia Tech, USA)*
As global urbanization trends continue to expose a very large percentage of the world’s population to natural disasters, the work of researchers like Dr. M. Nakashima have had profound impact on our ability to improve community resilience. Ranging from his work on detailing of steel structures to his leadership of E-Defense, and particularly on his extraordinary emphasis on international partnerships, the work of the Nakashima Laboratory has resulted in a more sustainable and resilient infrastructure. In this brief presentation, I will highlight some of Dr. Nakashima's contributions, with emphasis on the NEES Consurtium/E-Defense interations.

【講演者の紹介】
*Masayoshi Nakashima*  is professor of Kyoto University since 2000.  His areas of research include stability, ductility, and seismic analysis and design of steel members and frames and development of large-scale structural testing techniques including hybrid simulation and shaking table test.  He has supervised over 100 graduate students and post-docs, including 29 doctoral students, and published about 200 papers in archival journals. Currently, he serves as President of Architectural Institute of Japan and President-Elect of International Association for Earthquake Engineering.

*Riccardo Zandonini*'s studying career was at the Milan University of Technology. He devoted his research work to various problems in the field of steel and composite steel-concrete structures, comprising stability, connections performance, seismic response and robustness. This activity led to more than 200 publications. Currently, he is Professor of Steel Structures at the University of Trento. He served as Vice-President of International Association of Bridge and Structural Engineering (IABSE) from 2007 to 2015. He is Co-Editor of the Int. J. of Advanced Steel Construction (HK).

*Charles Roeder*  is a Professor of Civil Engineering at the University of Washington.  He has performed extensive research on the seismic performance of steel and composite structures, and his research has focused on the seismic performance and rehabilitation of braced frames for the past several years.  He is a member of AISC, SEI, and ASCE, and he serves on the AISC 358 and 341 standards committees.

*Roberto Leon*'s research interests have centered on dynamic behavior and design of composite and hybrid steel-concrete structures, composite action in beam-slab systems, bond of　reinforcement under cyclic loads, testing of full-scale and model structures in the laboratory, and field instrumentation of structures. Dr. Leon was president of the NEES Consortium and the Structural Engineering Institute of ASCE.
