High-Cycle Fatigue of Diagonally-Cracked RC Bridges
Large numbers of conventionally reinforced concrete deck-girder (RCDG) bridges remain in-service in the national highway system. Diagonal cracks have been identified in many of these bridges, which are exposed to millions of load cycles during service life. The anticipated life of these bridges in the cracked condition under repeated service loads is uncertain. Stirrup strain data were collected from in-service RCDG bridges and experiments were performed on full-size girder specimens to evaluate possible deterioration in load-carrying capacity under repeated loading. Specimen variables included: T and inverted-T configurations, stirrup spacing, and flexural reinforcing details. Test results indicated bond deterioration increased diagonal crack displacements and analysis methods to predict the shear capacity of diagonally-cracked reinforced concrete girders subjected to high-cycle fatigue damage are provided.
