global strategy for asthma management and prevention

The MISST structure is based on the Collector-Distributor 36 of the I-10 Santa Monica Freewaywhich was damaged during the 17 January 1994 Northridge Earthquake. To utilize currentNEES experimental facilities and for simplification, an idealization of the original structure wasemployed (Figure 1). As shown, the bridge is assumed to have three piers of varying height andis supplemented with soil models to include the effects of soil-structure interaction. The SantaMonica strong motion record was used exclusively throughout this investigation.As subsequently detailed, the project utilized the large-scale NEES facilities of both UIUC andLehigh University, in addition to advanced geotechnical modeling at RPI, to fully model thebehavior of the MISST structure. In an effort to manage the broad and complex scope of theproject, testing was approached incrementally. As such, several subtasks were developed and arein various stages of completion. A description of each follows.27.215 m 23.700 m 32.260 m30.795 m6.085 m6.575 m 6.085 mFigure 1. MISST test structureSingle pier component testTo reconstruct and verify the failure mode observed in the freeway structure, a single large-scalepier specimen was constructed and tested at UIUC. Figure 2 provides a comparison between theobserved behaviors. As shown, the laboratory test successfully reproduced the shear failureobserved in the field.Distributed analytical simulationa.
