  5. Multi-Site Soil-Structure-Foundation Interaction Test (MISST) At UIUC: Bill F. Spencer, Amr S. Elnashai, Dan Kuchma At Lehigh: Jim Ricles At RPI: Tarek Abdoun and Ricardo Dobry

  6. Introduction • The MISST was intended to provide a realistic test bed application with which to verify • all components of the NEESgrid • all components of the sites taking part in the distributed simulation • The behavior of a complex bridge structure including soil-structure interaction will be investigated • The collaborating partners of MISST • University of Illinois at Urbana-Champaign (UIUC) • Lehigh University (Lehigh) • Rensselaer Polytechnic Institute (RPI)

  7. Test Structure • The MISST structure is based on the Collector-Distributor 36 of the I-10 Santa Monica Freeway • It was damaged during the 17 January 1994 Northridge Earthquake • Unusual pattern of failure • Idealization of the original structure • To utilize current NEES experimental facilities and for simplification • Large-scale NEES facilities of both UIUC and Lehigh University, • Advanced geotechnical modeling and possible centrifuge test at RPI

  8. Multi-Site Simulation • The structure is subdivided into 5 static modules • MISST utilizes several aspects of simulation that will comprise many of the applications of the NEES experimental sites and NEESgrid by including: • Advanced analytical geotechnical modeling (or testing) • Advanced analytical structural modeling • Advanced structural testing using multi-degrees-of-freedom testing facilities

  9. Test Schedule Pretest with UIUC and Lehigh Test Setup Small Amplitude Test Large Amplitude Test Small Scale Test Large Scale Test

  10. Damage to the Santa Monica Freeway Collector-Distributor 36

  11. UI-SIMCOR Multi-Site Simulation System Sub-Structuring Technique NEESgrid NCSA Lehigh UIUC RPI RPI

  12. Comparison Damage to the Santa Monica Freeway Failure in the Earthquake Failure in the Laboratory

  13. Preliminary Pier Test at UIUC

  14. MISST Experimental Setup • Multi-site pseudo-dynamic test allows us to investigate seismic behavior of large-scale structural system with soil-structure interaction using NEESgrid environment. • Multi-site simulation framework has been theoretically verified to be effective.

  15. NEESR-SG: Seismic Behavior, Analysis and Design of Complex Wall Systems At UWash: Laura Lowes and Dawn Lehman At UIUC: Dan Kuchma At UCLA: Jian Zhang

  16. Experimental Test Program SSI Boundary Conditions Load History Moment Gradient Unidirectional Loading Flanged Planar (2) Coupled Bidirectional Loading Core-Wall System

  17. Planar Wall Tests Figure 3 Analysis of Coupled-Wall System

  18. C-Shaped Wall Tests • Depiction of a test specimen in the UIUC NEES facility

  19. NEESR-SG-2005 Seismic Simulation and Design of Bridge Columns under Combined Actions, and Implications on System Response University of Nevada, Reno University of Illinois, Champaign-Urbana University of Missouri, Rolla University of California, Los Angeles Washington University, St. Louis

  20. Causes of Combined Actions • Functional Constraints - curved or skewed bridges • Geometric Considerations - uneven spans or different column heights • Multi-directional Earthquake Motions -significant vertical motions input or near field fling impacts • Structural Constraints - stiff deck, movement joints, soil condition and foundations

  21. Small Scale Testing Facility, UIUC

  22. Shake Table Facility, UNR

  23. UMR Shaking Table Program PI - Belarbi

  24. UIUC – Simulation Program PI - Elnashai

  25. UNR Testing Program PI and Project Coordinator - Sanders

  26. International Cooperation • University of Mexico • E-Defense

  27. Analysis, Education and Outreach • Analysis • System analysis at UCLA (Jian Zhang) • Distributed (hybrid & analysis) at UIUC (Elnashai) • Education and Outreach • Education site and web models at WU (Dyke) • Outreach visits and hosting by all

  28. Outcome • Member Tests • Effect of design and detailing on failure of members under multi-axial (axial, bending, shear, torsion) conditions • Recommended design guidance on member level • Bridge Simulations • Effect of multi-axial excitation on bridge response • Design recommendations on the system level
