| Abstract: | Based on the strength criterion of the incremental plastic collapse, the inelastic deformation behavior of a ship's hull girder under cyclic bending loads was discussed in detail in this paper. A simplified analysis method for the ultimate strength of ship's hull girder under cyclic bending was proposed. Cyclic bending tests of a box girder with longitudinal stiffeners were also carried out. The computed results agree reasonably well with the experimental results. |
