A method for stress analysis of ring-stiffened cylindrical shell

ZHU Bang-jun, WAN Zheng-quan(China Ship Scientific Research Center, Wuxi 214082, China)  
A new method was developed for the stress analysis of ring-stiffened cylindrical shell based on the solutions of the web,flange and cylindrical shell.The effects of the eccentricity of ring-stiffener on the stresses of cylindrical shell and ring-stiffener were presented by comparing the present results and the code calculations.The numerical example shows that the difference of the calculated stresses exists between the inner-stiffener and outer-stiffener of cylindrical shell.The present method is employed instead of the code calculation for stress analysis of the cylindrical shell stiffened by the big inner-stiffener because the code calculation gives the underestimation of the stresses.
