Ultimate Longitudinal Strength of Ship Hull Girder: Historical Review and State of the Art

摘要

This paper introduces the historical matters and state of the art regarding the research works on the ultimate longitudinal strength of a ship hull girder. At first, it is described how the longitudinal strength assessment started, and past experimental works on full-scale and small-scale hull girders applying longitudinal bending load are introduced. Then, it is explained how the yielding and buckling affect the progressive collapse behaviour of cross-section of a ship's hull under longitudinal bending, showing the results of example calculations. After this, the methods of analyses as well as research works on ultimate longitudinal strength and progressive collapse behaviour of a ship's hull are reviewed, and some important results are introduced. At the end, bench mark calculation on progressive collapse behaviour under longitudinal bending is described.
