Abstract
From lessons learned after the 2011 Tohoku earthquake, it is clear that the quick procurement of an emergency public shelter and restoration of the city function are very important in the event of a disaster. This paper focuses on effects of the seismic repair to the residual out-of-plane deformations in local buckling region of steel column. The major findings obtained from the test are summarized as follows: (1) the RA repair method brought the strength recovery from the residual strength and the maximum strength is larger than the original one; (2) RF and RW repair methods also brought the strength recovery from the residual strength, however, the maximum strength is roughly same to the plastic moment of the original column.
