摘要: |
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. / NOTE:Research rept.
