Abstract

Deterioration of the end regions of prestressed concrete bridge girders is commonly observed in the field when girders are exposed to chloride-laden water that has leaked through failed expansion joints. Because the deterioration is often localized to the end regions of the girders, reliable repair techniques can provide a means to extend girder service life, avoiding the need for immediate superstructure replacement. To evaluate different repair methods and identify key design considerations for end region repair, shear tests to failure were conducted on prestressed concrete girders extracted from a decommissioned superstructure. Three repair systems were evaluated: an externally bonded fiber-reinforced-polymer (FRP) system, a near-surface-mounted FRP system, and a concrete end block. Only the externally bonded FRP system successfully restored both the strength and initial stiffness of the girder. Although the other two methods were not successful, the tests on the repaired girders highlight important factors that must be considered when designing repairs or conducting further research. The tests also demonstrate that end region deterioration can cause significant (> 40%) reductions in strength, underscoring the importance of addressing such deterioration observed in the field.

Abstract

Leaking longitudinal joints are commonly observed in adjacent box-beam bridges and are often associated with an assumed loss of load distribution at the leaking joint. To address the lack of test data and general uncertainty in analyzing deteriorated concrete structures, a series of load tests was conducted to determine the load distribution of a deteriorated adjacent concrete box-beam bridge. Load distribution was investigated for the existing structure with leaking joints as well as for the structure following rehabilitation with a noncomposite reinforced concrete deck. The bridge was tested in four conditions: as built, after removal of the bituminous wearing surface, after the shear keys were disabled, and with a reinforced concrete deck installed. Load distribution was assessed for each condition, and the results were compared with design equations. In addition to assessing load distribution of the existing bridge, the results of this study can serve as support for the use of a concrete deck as a rehabilitation strategy to restore load distribution or function as the primary load distribution mechanism of an adjacent box-beam bridge.
