• Abstract:
  As part of a work assignment issued by the Mississippi Department of Transportation, ; Bridge Division, the following report has been prepared to document results of an ; investigation of seismic vulnerability of the primary structural elements supporting the ; deck of the existing I-55 Undercrossing at MS-302 (Goodman Road). In order to assess ; the complex nature of the response to seismic excitation, a multi-level analysis has been ; performed, including: 1) a two-dimensional pushover analysis of a typical bent, 2) an ; eigenvalue and linear response spectrum analysis of a three-dimensional, fixed-base, ; finite element model of the four-span, concrete structural system, and 3) a threedimensional, ; nonlinear, time history analysis of the soil-structure system including the ; embankments and the soil column to a depth of about 100 ft below the deck level.
