| 摘 要： | 针对国内尚无有关蜂窝构件的规范或标准可以执行的实际情况，进行了蜂窝梁腹板在纯弯状态下的稳定问题研究。基于薄板的弹性稳定理论，建立了孔口处腹板和孔间处腹板的计算模型；应用能量法，得出了板的稳定方程，确定了板的高厚比限值和最小弯曲刚度，可供有关设计参考．

| Abstract: | As there is no criterion or standard about castellated member at home, study of the web stability of castellated beams under pure bending condition is carried out. Based on elastic stability theory of thin plate, the calculation model of web between opening and web above opening of castellated beams are formulated.Using energy method, the stability equations are deduced,and the depth-thickness ratio and minimum bending ripe are decided. These can be consulted by designs. |

| Keywords: | web of castellated beams pure bending condition local stability depth-thickness ratio minimum bending rigidity |
