Director's Letter

This is the thirty-first update to the community since NEEScomm was established on October 1, 2009 as the headquarters of NEES Operations.  In closing the calendar year of 2012, the ninth year in operation since officially opening its doors in October 2004, NEES is accelerating improvements in seismic design and performance in unprecedented ways, by serving as an indispensable collaboratory for discovery and innovation.  In the research news section of this update, the sample of projects highlighted clearly illustrates the global reach of NEES; and the NEEShub (https://nees.org), the platform for collaboration of the NEES community, further magnifies it with 5,700 registered users from more than 180 countries.

In 2013, NEEScomm will partner with users of NEES to capture and broadly disseminate the impact of NEES.  The first project to accomplish this goal is described on the NEES Project Highlights Callout Section of this update.  We look forward to working with you and need your collaboration in completing this important task for all of us.

We look forward to another year of great accomplishments of the NEES community and wish you all a 2013 full of good health and success!

Sincerely,

Julio Ramirez
NEES Chief Officer and NEEScomm Center Director


 



Update on NEES Grand Challenge Project on the Seismic Response of Nonstructural Systems

This month the large-scale capstone test of the Grand Challenge Project Seismic Performance of Nonstructural Elements was carried out using a two-story frame mounted on multiple shake tables at NEES@Reno under the direction of the project Principal Investigator Prof. Manos Maragakis from the University of Nevada, Reno.  The nonstructural components included full-scale partitions, suspended ceilings, and sprinkler piping layouts.

Experiments began on December 11, 2012 starting with a 25 percent of motion-simulated earthquake, moving upwards of 75 percent of motion over a two-day course.  The experiments were conducted to establish the following:

  • response of the nonstructural components, as part of a system under large drifts/accelerations
  • interactions within and between the nonstructural components
  • interactions between the components and the structure
  • effects of structural yielding on response of the nonstructural components

NEES@Reno provided a unique experience where online viewers could watch the tests live and Prof. Maragakis delivered audio descriptions of the test through the use of a webcam and audio equipment.  This great video footage along with the video of the equipped interior rooms are posted on their Facebook page at http://www.facebook.com/EQSimLabUNR.  As Prof. Maragakis mentioned during the webcast, preliminary conclusions will soon be available linked from the project homepage at http://www.nees-nonstructural.org/.

Data obtained from this project will be archived and made publicly available in the NEEShub Project Warehouse (http://nees.org/warehouse).

T-Rex Heads to Christchurch

With the recent NSF award of a RAPID/EAGER project, NEES@Texas under the direction of Principal Investigators Henri Gavin, Brady Cox, and Ken Stokoe will be performing deep soil profiling at the Christchurch Women's Hospital, located in Christchurch, New Zealand.  The research objective of this project is to measure the long-term seismic responses of the base-isolated hospital and to use these measurements, along with computational models, to asses the relative effects of soil-foundation-structure interactions with liquefying soil, for interactions between adjacent bulidings, and for interactions across the isolation interface.

With the use of the NEES@Texas T-Rex truck, nine networked triaxial accelerometers and three displacement sensors, installed at three levels within the structure, will allow for remote monitoring of aftershock responses and rapid data processing.  Read More
