为解决六边形孔蜂窝梁畸变相关屈曲的问题,采用参数研究的方法,提出了一个有效的非线性有限元模型,在有限元模型中充分考虑了几何非线性和材料非线性,并且该有限元和已有的试验资料进行了对比分析,结果表明,该有限元模型具有足够的精确性,腹板畸变屈曲的出现导致了蜂窝梁极限载荷显著减少,翼缘的厚度对蜂窝梁的极限载荷影响最大,翼缘的宽度对蜂窝梁极限载荷的影响次之,高强钢材在以畸变屈曲为控制指标的蜂窝梁中的应用时不经济. In order to solve the problem of distortional buckling of hexagonal-hole honey-comb girder, an effective nonlinear finite element model is proposed by using parametric method. Geometrical nonlinearity and material nonlinearity are fully considered in the finite element model. And this limited Element and the existing experimental data were compared and the results showed that the finite element model with sufficient accuracy, the emergence of web distortion led to the honeycomb beam significantly reduced the ultimate load, the thickness of the flange of the honeycomb beam ultimate load The influence of the width of the flange on the ultimate load of honeycomb beam is second, and the application of high strength steel in the honeycomb beam with distorted buckling as control index is not economical.
