Effectiveness Evaluation on Prestressed Continuous Box Girder Bridge Strengthening with Prestressing

Abstract:

This paper presented the deterioration condition and strengthening measures of a prestressed continuous box girder bridge. Finite element model of the bridge was built and condition was assessed according to current codes. Strain and deflection were measured through loading test to assess the stiffness in-service and the carrying capacity of the strengthened bridge. The results indicate that the carrying capacity limit state and serviceability limit state of the bridge are improved.
