The Multi-Site Soil-Structure-Foundation Interaction Test (MISST) was performed on May 16 and 17, 2006. MISST, a Pre-NEESR project, was conducted by collaborating partners at the University of Illinois at Urbana-Champaign (UIUC), Lehigh University, and Rensselaer Polytechnic Institute (RPI) and was established to provide a realistic test-bed application in which to verify and extend all components of NEESgrid as well as all components of the sites taking part in the distributed simulation. Concurrently, it has extended and represents the current state-of-the-art in distributed and integrated experimental-analytical earthquake engineering simulation. MISST was established to extend and build upon the Multi-Site Online Simulation Test (MOST) which took place on July 30, 2003 (Spencer et al, 2004). MOST was the first geographically distributed experimental simulation to make use of the relatively young George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES). The MOST simulation utilized NEESgrid, the NEES cyber infrastructure, to combine a numerical model run at the National Center for Supercomputing Applications (NCSA) with experimental tests being conducted at UIUC and the University of Colorado at Boulder. Similarly, MISST applied this distributed hybrid approach to simulate the response of a bridge structure which was partitioned into five separate modules distributed at three of NEES equipment sites: namely, UIUC, Lehigh, and RPI.
