3-D Nonlinear Finite Element Analysis was adopted to know the shear resistant performance of R/C short-column that had been seismic strengthened by carbon fiber sheets (CF-sheet). Four RC short column specimens were selected for analysis, which had differences in existence of carbon sheet, column axial stress. The commercial FEM application of "ATENA 3D" is used for this study. The carbon fiber sheets are modeled by the truss element that had the same area as the specimen. Concrete and CF-sheet were connected with the assumption that perfectly. The followings are drawn by the analysis; 1) An analytical result of the strengthened specimens without axial load were almost equal to an experiment result.2) Concrete compressive strut distribution within the column section was varied with strengthening. 3) The analytical result of the specimen which was failed in shear at the experiment showed the good correspondence.4) The both analytical and experimental ultimate strength can evaluate by past proposed equation
