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

22. 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
