Recently, prestressed concrete box-girder bridges have been increasingly constructed in many countries. Therefore, the effective management of the bridges and the assurance of safety and serviceability is required. The conventional method considers seperately the condition assessment based on the visual inspection and the load-carrying capacity based on structural analysis without considering the degree of deterioration of the structures. To improve the current condition assessment and safety evaluation system of PSC box girder bridges, an improved performance assessment of PSC box girder briges has been proposed in this study. The proposed method considers not only inspection results but also structural performance based on degree of deterioration in order to assess the overall condition of PSC bridges.
