  1. From the study results it is showed that turret hole position near the forward of the midship has less effect to the ship girder strength and it is more reasonable using probabilty statistics method to estimate the extreme value of wave bending moment, by which the first approximate value of hull midship section modulus can be determined

    研究結果表明：轉塔開孔位置在舯前附近對船體總強度影響不大；波浪彎矩極值用概率統計方法估算更為合理；船體結構剖面模數的第一近似值可用波浪彎矩設計極值等來確定。
  2. Then, a step - by - step increase of vertical bending curvature is applied to the hull girder assuming that the plane cross section remains plane. at each incremental step, the stress of the cross section is evaluated using the average stress - strain curves of the elements as well as the incremental bending moment due to the curvature increment

    船體總縱極限彎矩的計算，由於要計及材料的和幾何的非線性因素而變得十分復雜，必須用增量的方法逐步計算，獲得完整的彎矩?曲率曲線后，才能得到總縱極限彎矩值。
  3. Then, a step - by - step increase of vertical curvature is applied to the hull girder assuming that the plane cross section remains plane. at each incremental step, the stress of the cross section is evaluated using the average stress - strain curves of the elements as well as the incremental bending moment due to the curvature increment. performing sample calculations on existing girder models tests under pure bending, the rationality of the proposed method was examined

    假設船體橫向框架材足夠強，因而板架的整體破壞不會發生；基於梁?柱理論、理想彈塑性假設、平面假設，建立了拉伸和壓縮加筋板單元的平均應力?應變關系曲線，應用船體結構總縱極限強度的簡化逐步破壞分析方法計算船體總縱極限彎矩，並據此開發了計算程序sus 。
  4. The ferry - borges load combination method is applied to combine the stochastic processes of stillwater and wave bending moments, and the failure of ship hull girder occurs when the combined value of stillwater and wave bending moments exceeds the first yield bending moment

    另一方面，船舶在服役期內要定期接受檢驗，一旦發現船體構件嚴重受損，則要對其進行修理。遭受損傷的構件在維修后能恢復其對船體強度的貢獻，從而提高船體梁的可靠性水平。
  5. The concept of the longitudinal strength of ship hulls has changed and advanced greatly as the study on the failure mechanism of the hull is getting deep. by taking account the failure modes of yielding, buckling and their combination, as well as the non - linear interactions between structural members, the ultimate longitudinal bending moment is defined by the moment corresponding to the point with zero slope on the moment - curvature curve of the ship hull

    但隨著對船舶破壞機理的認識和研究發現，在研究船體的總縱極限強度時，必須考慮構件的屈曲、屈服等各種可能的破壞模式，要考慮受壓構件屈曲后及崩潰后的非線性性能的影響，要考慮組成船體的各個構件發生破壞的漸進性質和相互作用等。
