复合材料梁结构由于工艺性、维护性等要求，结构梁腹板中出现开孔不可避免，不同形式的开孔有着不同承载能力。通过对梁腹板结构不同形式的开孔在剪切载荷下屈曲分析研究，得到屈曲载荷，分析不同开孔补强形式对结构承载的影响，以期为梁、肋等结构开孔补强设计提供补强形式选择和参考。

In order to satisfy manufacture process and maintain requirement, a hole is ineluctable on the web of CFRP spar, difform size hole should have different carrying capacity, receive different buckling load. Finite ele-ment analysis was used to analyze the buckling behavior of the web, and analysis structure capacity of effect due to different strengthen methods,for supplying choice and reference.
