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.
