| Abstract: | A kind of special engineering structure, the stiffened cylindrical shell with a circular plate dome, is discussed with the semi-analytical method. The bending formula is derived with the analytical method for the circular plate under distributed loading, distributed inner force and distributed outer moment at the same time. With the transfer matrix method, the cylindrical shell is analyzed under applied distributed pressure, and distributed moment and force at the edge of the shell. The state variables are obtained by solving the equations based on the assumption that the deformations are equal at the edge. The result of a numerical analysis shows that the moment acting at the shell edge gives a larger bending stress in the shell. |
