1. 4 th NEES Annual MeetingKenneth H. Stokoe, II Washington, DCJune 22, 2006 Collaborative Activities of a NEES Equipment Site: Examples from nees@UTexas

2. Outline Mission of Equipment Sites Introduction to nees@UTexas On-going NEESR Projects On-going non-NEESR Projects Education, Outreach, and Training

3. Mission of Equipment Sites 1.Equipment Sites (ES) facilitate large-scale field and laboratory experiments that were not possible before the NEES Collaboratory maintain, operate and enhance the major pieces of the testing equipment educate potential users, advise and assist in proposal preparation, participate in safely conducting the experiments, and assist in importing data to NEEScentral 2. ES support education, outreach and training activities

4. Introduction to nees@UTexas

5. Personnel at nees@UTexas PI: Kenneth H. Stokoe, II Co-PI: Ellen M. Rathje Co-PI: Clark R. Wilson Operations Manager: Farn-Yuh Menq Computer Systems Analyst: Christopher Stanton Vibroseis Specialist: Cecil Hoffpauir Mechanical Technician: Andy Valentine Electrical Technician: Frank Wise Administrative Staff: Teresa Tice-Boggs and Norma Gonzales

6. Overview of nees@UTexas Equipment Site Function: dynamic field testing of geotechnical and structural systems with large-scale mobile shakers Equipment: Three mobile shakers with diverse force and frequency capabilities Tractor-trailer rig to move shakers Instrumentation van + trailer Wired and wireless data acquisition systems State-of-the-art field instrumentation Tele-presence capabilities for remote researcher interaction

7. Tri-Axial Shaker (“T-Rex”) Buggy-mounted vibrator Total weight – 64,000 lb (29,030 kg) 32 ft (9.8 m) long 8 ft (2.4 m) wide 3 Vibration orientations –Vertical –Horizontal in-line –Horizontal cross-line Uses vegetable-based hydraulic oil (Mobile EAL 224H)

8. Hollow Push Rod Liquefiable Layer Liquefaction Sensor Wire Rope and Electrical Cable Hydraulic Cylinder Installation of Embedded Sensors

9. Low-Frequency Shaker (“Liquidator”) Built on same platform as the T-Rex Optimized for low-frequency (down to 0.5 Hz) force output

10. Urban Shaker (“Thumper”) Built for high-frequency force output (beyond range of T-Rex and Liquidator) Built for use in urban environments Total weight = 22,600 lb (9,980 kg) Peak force = 6,000 lb (26.7 kN) Transformable to operate vertically or horizontally

11. Tractor-Trailer Transport System (for T-Rex and Liquidator)

12. Instrumentation Van + Trailer

13. On-going NEESR Projects

14. Collaborative Research: Using NEES as a Testbed for Studying Soil-Foundation-Structure-Interaction PI: Sharon L. Wood Universities involved: University of Texas at Austin, Purdue University, University of California–Davis, University of Nevada- Reno, University of Washington-Seattle, and University of California–Berkeley

15. Field Evaluation of Liquefaction Resistance at Previous Liquefaction Sites in Southern California (Imperial Valley) PIs: Kenneth H. Stokoe, II and Ellen Rathje nees@UCSB Wildlife Refuge Liquefaction Field Site

16. Study of Surface Wave Methods for Deep Shear Wave Velocity Profiling Applied to the Deep Sediments of the Mississippi Embayment PI: Brent Rosenblad Liquidator MORT strong motion Station at Tiptonville, TN

17. On-going Non-NEESR Projects (also “Outreach” Activity)

18. Spectral-Analysis-of-Surface-Wave (SASW) Testing at Yucca Mountain Site PI: Kenneth H. Stokoe, II

19. Education, Outreach, and Training

20. Education: Undergraduate Foundation Engineering Class

21. Education: Graduate Soil Dynamics Class

22. Education: Demonstration at an Elementary School in Gosnell, AR

23. Topic: exploring the potential of a multi-facility and multi-funded approach to solving scientific and engineering problems Where: University of Texas, Austin, Texas When: April 29 and 30, 2004 Recent Outcome: 3 projects Outreach: NEES/IRIS/USGS Workshop Primarily funded by IRIS and USGS Spearheaded by Joan Gomberg, USGS 31 invited participants

24. Outreach: NEES/IRIS/USGS Workshop

25. Up Coming Users' Training When: mid November, registration opens on October 1st. What: choosing the right equipment, budget planning, test scheduling, and using SingleShot. Why: get your NEESR proposal done faster. Where: WebEx based on-line training – no traveling cost!
