This laboratory study concerns the use of carbon composites to restore the seismic effectiveness of corrosion-damaged reinforced concrete bridge columns with inadequate length lap-spliced reinforcement at their base and subjected to severe environmental conditions. Large-diameter reinforced concrete columns were corroded using external currents, repaired with different layouts of carbon composite material, and then tested to failure under lateral cyclic loading. Bond degradation due to corrosion dictated the losses in ductility and load capacities for the corroded columns. Columns retrofitted with carbon composites, and having well-consolidated repair concrete had maximum load and ductility capacities exceeding those of a control column, which simulated the original as-built condition.
