摘要
根据递增塑性破坏的强度准则，详细讨论了循环弯曲载荷下船体梁的非弹性变形性能。给出了循环弯曲载荷下船体梁极限强度的简化分析方法。进行了纵筋加强箱形薄壁梁模型的循环弯曲试验。理论计算与试验结果作了比较，两者吻合较好。
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.
