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

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.

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
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

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

30
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
