Abstract
This report presents the of seismic evaluation of the Ohio river bridge on US51 at Wickliffe, Kentucky. The main bridge is a five-span single-deck cantilever through-truss type. The approach bridge has 21 spans on the Kentucky side and 6 spans on the Illinois side. Although this bridge has not yet been subjected to a moderate or major earthquake, it is situated within the influence of the New Madrid seismic zone. The seismic evaluation program consists of field testing and seismic response analysis. The modal properties of the main bridge are determined through field testing, and are used to calibrate the three dimensional finite element model. The finite element model is then subjected to time histories of the 50-year earthquake event. Stresses and displacements obtained are within the acceptable limits. Analytical results indicate that the main bridge will survive the projected 50-year earthquake without significant damage and no loss-of-span. Hence, it is not recommended to retrofit the main bridge. The approach spans are analyzed using response spectrum method with simplified single-degree-of freedom models. Most of the Kentucky and Illinois approach spans require additional anchor bolts at the bearings.
