Abstract:The report outlines a rating system and details an evaluation procedure for the seismic evaluation of highway bridges. These processes are later used to investigate the structural integrity of selected highway bridges on and over the parkways in Western Kentucky. A total of 349 bridges were rated with the bridge ranking system, and 17 were selected for detailed seismic evaluation.
The evaluation involves creating three-dimensional finite element models for all 17 bridges. Dynamic analysis is performed for a projected 250-year event. Among the four components required for proper evaluation, only expansion joints and bearings, and columns and footings were investigated.
