Abstract:

The main objective of this study is to assess the structural integrity of the I-24 parallel bridges at the Cumberland River crossing in western Kentucky. Due to its importance, the bridge is evaluated for the 250-year event and the maximum credible 500-year event. The scope of the work included: 1) Field testing of the main bridge; 2) Finite element modeling and calibration; 3) Time-history seismic response analysis for the main spans; and 4) Seismic evaluation for both the main and the approach spans. ; The seismic analysis for the 250-year event indicates that the main spans of the bridge can resist the event without yielding or loss-of-span at the supports. However, the anchor bolts on some of the piers are expected to fail in shear. Retrofitting measures are recommended. ; The seismic analysis for the 500-year event shows that few members of the main spans would yield due to the event. Also, the capacity of the bearing shear bolts of few piers of the main and approach spans are exceeded, and retrofitting measures are recommended.
