The purpose of this study has a purpose to evaluate shear ability, ductility and energy dissertation of specimens that is to be applied to jacket using wrapping method. The experiments was conducted as a condition that simultaneously applied axial load and transverse force. The results of experiments represent story-displacement ratio, the stiffness, energy dissertation, plastic rotation which mean seismic resistance ablity on structure. And It represents the form of crack ditribution and failure in extreme stages. Based on the results of this experiment, Design examples are given to show the performance evaluation for the column reinforcing of old school buildings using nonlinear analysis is going to be conducted. Therefore, it is possible to apply the seismic retrofit method to public facilities.
