Stability of ring-stiffened tubular members under external pressure
- Univ. of Texas, Austin, TX (United States). Dept. of Civil Engineering
The present work is motivated by the need for understanding of the stability of steel tubes, which are candidates for deepwater applications. Offshore compliant towers make use of tubular members, which are subjected to a combination of axial load, bending, and external pressure. Here, results are presented of a rigorous nonlinear finite element technique for the stability analysis of ring-stiffened steel tubes under external pressure. Large deformation, plasticity, as well as residual stresses and imperfections, are taken into account. Both internal and external stiffeners are simulated. A study of various parameters which affect pressure capacity is summarized, along with a comparison with available experimental data.
