Planning meeting for NEES/E-Defense Collaborative Research Scheduled for December 2013



The NEESWood Test Building being tested on the E-Defense Table in July 2009.

The large E-Defense shaking table facility in Japan has recently reopened following nearly a year of inactivity while major upgrades were installed.  These upgrades permit the facility to simulate large 3D earthquake motions having durations up to 40 minutes or more.  This new capability provides unique opportunities to improve understanding of seismic response due to long-duration ground motions, such as those associated with subduction zone faulting or cascading fault ruptures.

The annual Planning meeting for the NEES/E-Defense Collaborative Earthquake Engineering Research Program has been scheduled during Wednesday-Friday, December 11-13, 2013 in Kyoto, Japan.

The meeting will include a field trip to the E-Defense laboratory. During the visit, participants will learn about various upgrades, and witness an interesting test where a 1/3-scale model of a modern 18-story tall, steel moment-resisting frame building structure will be tested to collapse. The majority of the meeting will be devoted to learning about plans for use of the upgraded facility by E-Defense and other Japanese researchers, reviewing progress on various recent and on-going NEES/E-Defense research projects, and discussing and establishing the foundations for future NEES/E-Defense collaborative research projects.

The specific topical areas to be discussed at the meeting include: (1) high-performance reinforced concrete structures; (2) seismic isolation and structural control; (3) geotechnical engineering issues (focusing now on underground structures); (4) tall buildings; and (5) monitoring and condition assessment of structures and soil-structure systems.  Two overarching themes will also be discussed: (a) other needs, opportunities and priorities for future near and long-term US-Japan collaborative research, and (b) numerical simulation of seismic performance.   Various possible forms of collaboration are possible in this program, including participating in Japan initiated test programs, developing concepts for joint US-Japan tests, developing payload tests, conducting analyses utilizing test and sensor data, carrying out supporting tests in the US using NEES facilities in conjunction with Japanese partners, etc.  This meeting will provide opportunities for the interaction among US and Japanese researchers needed to plan such collaborative projects.

A registration site is being established to indicate your interest in participating in this meeting. A limited number of travel stipends are available. Selection of individuals to receive travel support will be based on achieving adequate technical expertise in each of the active working group areas, attracting new researchers and students to participate in US-Japan collaborative research, and insuring that NEES/E-Defense planning efforts benefit from a diverse and geographically distributed cross section of the earthquake engineering community, including women, disabled individuals and underrepresented minorities.
