WebJun 11, 2024 · Abstract. This research aims to investigate the efficiency of repairing damaged concrete columns using thin concrete jacketing. The experimental program included casting of nine reference 300 mm long reinforced concrete column specimens: three specimens had a cross-sectional dimension of 100 mm × 100 mm, three … WebColumn steel jacketing presents the best capability to improve the bridge ductility. By comparing results from the eighteen cases of different column retrofit combinations, it is concluded that the middle columns and columns with shorter effective height are more critical in improving the bridge longitudinal ductility.
