The effect of tri-connection technique applied in the strengthening of wall-supporting R.C.frame-column is discussed. Based on the results of the comparison tests of axial compression for short columns,it shows that after the application of tri-connection technique, the strength and ductility of columns have been improved dramaticly. The conclusion can be used as reference for projects which will be reconstructed or strengthened.
