Abstract: 
The residual structural performance of a real RC bridge that had been in service for 80 years in a coastal area of Japan was tested in the laboratory. The load bearing capacity of the bridge was examined, with the test results showing that the residual load bearing capacity of a heavily corroded RC girder was lower than indicated by the corrosive loss in reinforcement cross-sectional area. A simulation by nonlinear FE analysis implied that the very low ultimate load bearing capacity of the tested girder is attributable to the presence of reinforcement that is unable to bear tensile force due to damage to the lap splice joints. Laboratory tests using RC beam specimens with lap splices were carried out to clarify the reason for the damage to the lap splice joints.
