چکیده:

Stiffened cylindrical shells are an integral part of submarine and offshore structures. Ring frames and longitudinal stringers are attached to the shell in these structures. Also such structures are under a combination of different loads, among which the hydrostatic pressure and axial compression are of high importance. The focus of this study lies on the subject of buckling analysis of stiffened shells. In line with this research
need, the commercial finite element code ANSYS is utilised to simulate the collapse of stringer stiffened shells. Different parameters are considered in the finite element models.
