INFLUENCE OF IN-PLANE BOUNDARY CONDITIONS ON BUCKLING OF RING-STIFFENED CYLINDRICAL SHELLS

The effect of in-plane boundary conditions on the buckling loads of simply supported ring-stiffened cylindrical shells is studied. As in the case of unstiffened shells, the 'weak' in-plane boundary conditions SS1 and SS2 yield here critical loads about one half of the 'classical'loads. It was observed that the SS1 critical loads are identical with the SS2 loads and the SS4 loads are almost the same as the 'classical' SS3 loads. The combined effect of stiffener parameters and in-plane boundary conditions is studied. For internally stiffened shells the influence of in-plane boundary conditions is found to diminish with increasing values of stiffener eccentricity and area. No such effect is observed for externally stiffened shells. The buckling modes are also studied and found that they are dependent upon shell length and upon stiffener location and parameters.
