Abstract:
Rapid repair and retrofitting is increasingly urgent and significant for the earthquake-damaged columns. To restore the flexural strength, and also attempt to restore stiffness and deformation capacity of damaged columns, this paper proposes a repair technique using near-surface-mounted (NMS) basalt fiber reinforced polymer (BFRP) bars and BFRP sheets jacketing, and then four one-fourth scale earthquake-damaged reinforced concrete circular bridge columns repaired by the proposed technique are retested under the similar cyclic lateral load as the corresponding original columns. The repaired columns are compared with the original columns in the seismic behavior finally, and the results have shown that the flexural capacity of the repaired columns was restored and even enhanced; furthermore, the stiffness and the displacement capacity of repaired columns were restored to an extent that can meet the needs of a temporary repair and allow emergency service use after an earthquake. This implies that the repair technique is effective in restoring the flexural performance of the damaged circular bridge columns. (C) 2015 Elsevier Ltd. All rights reserved.
