An analysis on the stringer-stiffened cylindrical shell with a large interval ring is described. The buckling of the shell under axial compression is forecasted by the method of the Ultimate Load Method, to simplify the interconnection on steadiness between shell and stringers. Although the shell between stringers is semi-empirical modeled, the buckling of the stringers which are bolstered with the other stiffened component ring is analytically solved. It is show that support effect of the ring on the stiffened cylindrical shell is quantized by a ring coefficient. The buckling load of the stringer-stiffened cylindrical shell is calculated on the different length. Finally, the ring coefficient is used to explants the so-called shielding panel effect ring. The present results could be an important reference for the design of stiffened shell under axial compression.
