| 摘 要： | 腹板开孔的H型钢梁在船舶，航空器和海洋平台结构作为受弯构件被广泛运用。已有众多文献报道过关于腹板开孔梁遭受腹板卷曲破坏的情况，但腹板开孔加强遭受面板屈曲的情况未有详尽调查。因此文中开展6组试件的试验研究来调查腹板开孔的H型梁的失效行为和极限承载力，结果显示开孔影响了试件屈曲波的长度和数量。该研究结果可用于几何尺寸相似的实际结构。

| Abstract: | Steel H beams with web openings are widely used as flexural members in ships, aircrafts, and offshore structures. In spite of numerous papers in the literature on beams with web openings sub-jected to web crippling, the effect of stiffened web openings subjected to plate buckling has not been exhaustively examined. Hence a detailed experiment study involving six specimens was undertaken to investigate the failure behavior and ultimate capacity load of H beams with stiffened web openings. The results show that the wavelength and quantities of the buckling waves were modified by the hole. This study can be used in practical structures with similar geometric features. |
