Director's Letter

In this month's update, you will find information about the capstone experimentation in the NEES Grand Challenge Project on the Seismic Response on Nonstructural Systems, testing recently completed in the NEES-CR Earthquake Response and Rehabilitation of Critical Lifelines project and the NEEShub 4.5 Release.

The upcoming NEES Project Highlights book will have a new layout highlighting completed projects that have played an important role in earthquake and tsunami research.  We need your participation in this unique, debut publication.  Many have already been contacted but if any project has begun with some tests already completed, we would like to have a submission to be included on your behalf.

Contact Teresa Morris at This email address is being protected from spambots. You need JavaScript enabled to view it. before December 17, 2012 for submissions!

 

Sincerely,

Julio Ramirez
NEES Chief Officer and NEEScomm Center Director


 



 

NEES Grand Challenge Project on the Seismic Response of Nonstructural Systems

The capstone experimentation in the NEES Grand Challenge Project on the Seismic Response of Nonstructural Systems will begin in November 2012, using a two-story test bed frame with tunable dynamic properties mounted on multiple shake tables at the University of Nevada, Reno (NEES@UNR). The testing, under the direction of Principal Investigator Professor Manos Maragakis, who is also the Dean of the College of Engineering at UNR, will subject full-scale partitions, suspended ceilings, and sprinkler piping layouts, to earthquake motions. The tests are designed to investigate the system-level interactions of these nonstructural components under environments of high accelerations and/or large drifts.

 Previously in the project, component-level testing was done on partitions, ceilings, and piping at the University at Buffalo NEES equipment site, under the direction of Co-PI Professor André Filiatrault. In addition, a series of experimentally based simulation and public policy studies have been completed or are in progress. NEES Nonstructural Technical Reports generated on project findings to date are available for download as PDFs (link to files).

 The test bed construction at UNR has been completed and the construction of the nonstructural systems is in the final stages of completion. The first experiment is scheduled on November 27, 2012 and completion of the program is expected in early April 2013. Testing may be viewed by webcast. Details on precise schedules as test dates approach, and information on accessing web observation of the tests, will be available at:

Earthquake Response and Rehabilitation of Critical Lifelines

One area of concern in the aftermath of an earthquake is the usability of underground infrastructure. If the pipes leading to and from a city are damaged or inoperable, you lose those valuable lifelines for those living in the aftermath of the earthquake.

 In collaboration of the NEES equipment sites at Cornell and RPI, and under the direction of Principal Investigator Thomas O’Rourke, the NEES-CR Earthquake Response and Rehabilitation of Critical Lifelines project recently completed a series of major tests using a multi-sectioned, 6-inch diameter Ductile Iron (DI) pipe, first unlined and then followed with a DI lined pipe. NEES@Cornell has a basin 3.2 m wide and 15 meters long with a maximum depth of 2.1 m that allows testing of underground pipelines during ground rupture. The basin is split in the center along a 50-degree sliding plane, which allows for rupture at angles with a pipeline from -50 to 50 degrees. Four displacement-controlled actuators are grouped electronically to ensure identical actuator commands and uniform test basin movement.

 Read more about this project in the Project Warehouse and stay tuned for more information as this research concludes.

NEEShub Recent Releases

NEEShub users have seen many changes and new tools recently added to NEEShub.   Ten new tools contributed by NEES community members were released in late October. Following the tool release and after months of prep work by the NEEScomm IT staff, NEEShub 4.5 upgrade was implemented on November 14, 2012 with a focus on many usability improvements and enhancements. For complete release details, be sure to read the recent announcement on nees.org.

Do you have contributions to share or that you would like to see implemented in a future release? Visit https://nees.org/resources/new to learn how you can get involved!

Project Highlights Book Callout

NEEScomm publishes an annual activity highlights book that showcases NEES research.   The book is shared with the National Science Foundation, strategic partners and practitioners, and distributed at national and international conferences.   The upcoming publication will have a new layout highlighting completed projects that have played an important role in earthquake and tsunami research such as code change, seismic design improvements, etc.

Community members who have conducted research using NEES are encouraged to participate in this unique, debut publication. Many have already been contacted directly but if any project has begun with some tests already completed, we would like to have a submission to be included on your behalf.

Please contact Teresa Morris at This email address is being protected from spambots. You need JavaScript enabled to view it. before December 17, 2012 for submissions. Only submissions before December 17 will be guaranteed to be included.

 

NEES Outreach to the University of Texas, El Paso

On November 13, Prof. Julio Ramirez and Purdue School of Civil Engineering doctoral students Enrique Villalobos and Pedram Khajeshhesameddin, visited the University of Texas, El Paso, Department of Civil Engineering and shared with students and faculty the latest information about NEES, invited their senior and junior undergraduate students to apply to the NEES REU program next summer.

 In addition, Enrique Villalobos demonstrated the resources available for users on the NEEShub such as research and educational tools, databases, publications and the NEEShub Project Warehouse. His demonstration of the Project Warehouse showed students where the information that can be found in a project as well as visualize experimental data with the tool INDEED. Pedram Khajeshhesameddin led an activity that explored some of the simulation capabilities available at the NEEShub such as SAP2000 and PocketStatics. These simulation tools were demonstrated in an interactive session and participants also learned how to share their models on the NEEShub.

Oregon State Wave Flume Hosts Tsunami Challenge

NEES@OSU recently hosted first year OSU engineering students for the Tsunami Challenge and showed great promise of many pursuing civil engineering. The challenge included a four-step activity that involved an introduction to coastal engineering and problems specific to tsunamis; a specific challenge of protecting a “person” from a tsunami; received materials to build a vertical evacuation structure to protect the “person” represented by a Ping-Pong ball; and finally using the large wave flume to create a huge splash of waves to test the students’ models.

 The challenge is offered several times throughout the year for K-12 students and OSU undergraduates. At this latest challenge, The Weather Channel was present to film the test and interviewed Education and Outreach Coordinator Alicia Lyman-Holt for an upcoming new series. Stay tuned for programming details.
