| 摘 要： | 针对舰船结构中强梁腹板特殊开孔引起的应力集中问题，应用有限元法分析了开孔的垂向位置、孔的宽度、孔的长度对强梁整体强度的影响，以及其最大应力发生位置的变化规律，讨论了3种常用开孔补强方法的补强效果，并提出了一些供实际结构设计的参考意见。

| Abstract: | The effect of vertical locations, widths and lengths of the holes to the overall strength of the reinforced beams, and the varying rule of the location of maximum stress are analysed by using finite element method for the stress concentration problem raised by the special holes in the webs of reinforced beams in ship structures. The results of 3 common hole-reinforcing methods are discussed, and some recommendations are proposed for practical structure design. |
