Finite-element analysis model was established for hexagonal hole castellated columns with expansion ratio of 1. 4, as well as the model for solid-web steel members without expansion. Buckling analysis for the beam-columns of different eccentricities was carried out. And the bearing capacity for compressive members was obtained and analyzed.%利用ANSYS建立了扩张比为1.4的六边形孔的蜂窝钢柱的有限元模型,同时也建立了扩张前的原有实腹钢柱的有限元模型.对这些模型进行了在不同偏心距情况下的轴向压力作用下的屈曲分析,获得了各压弯构件的极限承载力,并做了对比分析.
