摘要
该文利用梁柱理论推导出复合材料梁柱的极限承载能力公式。讨论了加筋板的初始几何缺陷 ,载荷偏心 ,蒙皮屈曲后的有效蒙皮宽度对复合材料长帽形加筋板的极限承载能力的影响。利用复合材料梁柱理论计算船体甲板或船底板结构视加筋板单元构件的极限承载能力 ,最后由Smith法来计算复合材料船体的极限承载能力。
Long composite stiffened panel is thought as columns,and the ultimate strength of composite stiffened plates is derived from composite column theory.Initial geometric imperfections,eccentric load and effective width of plating are considered in deriving.Deck and ship bottom structures are supposed to be an assembly of a series of stiffened plates.The ultimate strength of each composite stiffened panel can be obtained by composite column theory.Finally,Smith method is applied to calculate the longitudinal ultimate strength of high speed composite ship hull.
