In this study, the repairability and recovery of damaged structural members are investigated experimentally. At first, test specimens which are damaged with local buckling or cracks are reproduced by loading test. Next, the damaged specimens with plastic residual deformation are returned to the original position. Finally, the loading test is done after the damaged areas are repaired. From the test results, the comparison and evaluation of recovery of stiffness, ductility and strength before and after repair are investigated. It is confirmed that ductility and stiffness of the repaired test specimens are recovered to the performance of original state.
