  1. UC Berkeley Reconfigurable Reaction Wall NEES Equipment Site NSF NEES Awardees Meeting Video-Teleconference

  2. Provide the means to do hybrid simulation involving several physical substructures using real-time pseudo-dynamic testing method from a remote location Mission of RRW ESF

  3. Hybrid Simulation Options MS-PDTM test High-Axial Load test Collapse Mechanism test

  4. Equipment • Actuators: • 2: 220 kips; +/- 10 inch; fast • 2: 150 kips; +/- 20 inch; fast • 3: 220 kips; +/- 36 inch; slow • Controller: real-time, digital, 8 channel • Network: 100Mb/s now, 2.5Gb/s in 2004 • Sensors: wired and wireless • Simulation engine: OpenSees

  5. Network

  6. Tele-Participation • MS-PDTM simulation • Real-time high-resolution video • PRoPs mobile robot avatar

  7. Status • RFPs for actuators, accumulators, and control and data acquisition system ready • Wall design ready for bidding • MS-PDTM prototype development on a dSpace ACE 1104 system started • Props robot in production stage

  8. Questions for SI • What are SI deliverables, milestones and schedules? • What is NEESpop? • Where does it fit in our LAN? • What are its specs? • Who pays for it? • Connection between NEESsite and NEESgrid: • Who will build it? • Who will make it work and maintain it?

  9. Questions for SI • Will SI support: • OpenSees • Matlab/Simulink • MTS Scramnet • Will SI provide training? Who will pay for it? • How will SI provide Internet security for a NEESsite? Who will be responsible?

  10. Questions for CD • How will policy be established? What mechanisms will be used to ensure that NEES policy is consistent with local policy at equipment sites? • What will be the relative roles of the consortium and the local equipment sites in setting access rules; use charges and personnel rates; schedules; outreach and advertising?

  11. Questions for CD • Data: • Who will choose data formats for archiving and exchange? • Who will determine when to release data? Who will have authorship rights? • Software: • Who will ensure that appropriate software is available for data archiving, visualization, simulation? • Who will fund development and maintenance of such software?

  12. Questions for CD • Researchers/students: • How will NEESsites be matched with researchers/students • Will student credit count for graduation at all NEES sites equally? • How will pay for educating the researcher/student on how to use the facility
