摘　　要：为了考察影响蜂窝状钢骨混凝土十字形柱承载力的因素,采用ANSYS软件对该柱进行了大量的有限元分析,研究了混凝土强度等级、钢材牌号、配筋率、配箍率及长细比等因素对该新型异形柱力学性能的影响.研究结果表明:混凝土、钢材强度、配筋率越高及长细比越小,柱子承载力越大;配箍率对柱子的承载力几乎没有影响.The influential factors, such as concrete strength, steel strength, reinforcement ratio, stirrup ratio and slenderness ratio, on the mechanical properties of the honeycomb SRC asymmetrical cross-shaped column ware analyzed by ANSYS software. The results indicate that the load-bearing capacity of the members increases with increases of concrete strength, steel strength and reinforcement ratio, and decrease of the slenderness ratio, while the effect of the stirrup ratio on the bearing capacity can be neglected.
