Outline of Final Research Achievements

When a double bottom of ships is subjected to bending due to lateral loads, bi-axial compression is exerted in the bottom plate and they affect the ultimate longitudinal bending strength of ship hull girder in the hogging condition. Under repeated wave loads, buckling deformation of bottom plate may be accumulated and this may further decrease the ultimate hogging strength. In this study, the ultimate hogging strength of a hull girder of container ships was analyzed by nonlinear FEM considering the effect of bottom local loads. The buckling/plastic collapse behavior of a continuous stiffened panel under repeated bi-axial thrust is examined both experimentally and numerically. The cumulative collapse behavior of a hull girder under wave loads was investigated by simplified collapse analyses and wave tank test. Based on the results, the effect of multi-axial stress states and repeated loading on the ultimate longitudinal bending strength of a ship hull girder is investigated.

Academic Significance and Societal Importance of the Research Achievements

コンテナ船の縦曲げ崩壊事故調査から、二重底の曲げ変形による二軸圧縮場が船底の座屈を加速し、さらに波浪繰り返し荷重が座屈変形を累積させて最終崩壊に至らしめた可能性が指摘された。本研究では、船底局部荷重を考慮したコンテナ船の縦曲げ崩壊挙動に関する数値解析、および二軸繰り返し圧縮荷重下の防撓パネルの崩壊試験および解析より、船体桁の縦曲げ最終強度に対する多軸応力と繰り返し載荷の影響を調べた。
