Effect of Soil Conditions on the Seismic Response of Three-Span Integral Abutment Bridges

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Integral abutment bridges (IABs) in Illinois can be subjected to a wide range of seismic hazard, particularly due to the proximity of the southern region of the state to the New Madrid Seismic Zone. The lack of expansion joints in IABs places a greater emphasis on the interaction between abutment piles and surrounding soil during seismic events. The present research incorporates soil-structure interaction into an IAB model that also comprehensively represents other critical components in order to determine overall seismic behavior of a three-span steel IAB in southern Illinois. The IAB is analyzed under three soil conditions-one based on actual soil property data in southern Illinois, and two representing realistic stiff and soft soil boundaries for southern Illinois. Results demonstrate the effects that soil conditions have not only on the foundation piles, but also on the IAB as a whole.
