摘　　要：为了进一步推广蜂窝梁在实际中的应用,针对中国结构设计规范尚未对此结构作出规定的现状,通过ANSYS有限元分析软件,采用板壳元建立不同参数的圆孔蜂窝梁计算模型,对圆孔蜂窝梁的静力性能进行研究,探讨了跨度、开孔率、孔间距等参数对梁强度、刚度和稳定性能的影响,并将计算结果与相同截面的实腹式构件对比,给出了较为简化的实用设计公式,为圆孔蜂窝梁的进一步研究与应用提供了参考。In order to promote the application of circular-hole castellated beams in practice, aiming at current situation that China relative code doesn＇t present the structure, using ANSYS finite element analysis software to build up castellated beam calculation modles with different parameters, some typical circular-hole castellated beams were studied in order to analyze the influences of some crucial parameters, such as span, pore ratio and interval of holes on the strength, rigidity and overall stability of simply supported castellated beams. The results were compared with those of beams without holes and a simplified method were put forward for castellated beams design in engineering practice, which could contribute to the further analysis and application.
