| Abstract: |
Felezi Bridge was built in Esfahan on the Zayandeh-Rood River in 1957. This bridge has five spans and the bridge deck has been installed on four concrete piers in middle and two abutments on both ends. Pursuing the bridge seismic rehabilitation plan of the Esfahan municipality, a comprehensive study of the said bridge was accomplished. Visual inspection and non-destructive tests results indicate some failures including rust, efflorescence, crack, scour, and settlement in some parts of the bridge. Also modeling and computerized analysis of the bridge structure using the recommended methods by the FHWA code specified the weak points of the structure under the gravity load, service load and seismic loads. Then the final sum-up and assessment of the bridge vulnerability as well as the bridge vibration improvement recommendations were made based on the results of visual inspection, non-destructive tests and the bridge structure analysis. |
