| 抄録 | In order to continue to use buildings that have been severely damaged by a major earthquake, it is necessary to clarify the resistance mechanism of the repaired members. In this paper, the actual column damaged by the first reversal loading was repaired with epoxy resin using spring cupsel. In addition, the damaged surfaces of the column were repaired with fiber mortar, the strength of which was lower than the strength of the original concrete. The total amount of epoxy resin injected into the damaged column was 9.6 kg. The retrofitted column showed almost the same crack propagation as the original column. The shear cracking strength and the maximum strength increased to 1.39 times and 1.32 times that of the original column respectively. It was confirmed that the maximum strength of the repaired columns increased to those of the original columns. |
